Data collection

Scope and coverage

The Criminal Courts, Australia 2023–24 publication presents information about defendants whose case was finalised in the criminal jurisdictions of the Higher (Supreme and District/County Courts), Magistrates' and Children's Courts across Australia’s states and territories, during the reference period 1 July 2023 to 30 June 2024. Information is presented about the offences, outcomes and sentences associated with these defendants.

Time series data are generally presented for 2010–11 onward. Additional data can be found in earlier versions of this publication: Higher Courts from 1995, Magistrates' Courts from 2003–04, and the Children's Courts from 2006–07.

The following are not within the scope of the Criminal Courts collection:

  • Civil and coroners court cases
  • Appeal cases (including criminal appeals heard by the High Court of Australia)
  • Tribunal matters
  • Cases which do not require the adjudication of charges (e.g. bail reviews, extradition hearings, and applications to amend sentences or penalties)
  • Defendants for whom a bench warrant is issued but not executed
  • Finalisations in specialist courts, such as Drug Courts and Fine Recovery Units
  • Pre-court diversionary programs (e.g. warnings, cautions, drug diversions, conferencing)
  • Bench warrants in the Higher Courts
  • Referrals to mental health review tribunals (e.g. for determination of fitness for trial)
  • Mistrials and hung juries, where the case is not finalised
  • The small number of criminal cases finalised in the Federal Courts

The following offences (based on the Australian and New Zealand Standard Offence Classification, (ANZSOC) 2011) are excluded:

  • Breach of home detention (1512)
  • Breach of suspended sentence (1513)
  • Breach of community service order (1521)
  • Breach of parole (1522)
  • Breach of bail (1523)
  • Breach of bond – probation (1524)
  • Breach of bond – other (1525)
  • Breach of community-based order, n.e.c. (1529)

Defendants finalised on Cocos (Keeling) Islands and Christmas Island are included in the counts for Western Australia, where applicable. Defendants finalised in Jervis Bay Territory and Norfolk Island are not included. 

Data source

Statistics presented in this publication are compiled based on administrative unit record data supplied to the ABS by the agencies responsible for courts administration in each state and territory, except for Queensland (where data are supplied by the Office of the Government Statistician), and New South Wales (where data are supplied by the Bureau of Crime Statistics and Research).

To ensure consistency between the states and territories, these agencies provide data coded to national classifications and standards.

Data processing

Counting methodology

The counting unit for this collection is the finalised defendant.

A finalised defendant is a person or organisation for whom all charges within a case have been formally completed so that they cease to be an active item of work for the court during the reference period.

The Criminal Courts collection does not count unique persons, instead the following rules are applied:

  • Where a defendant is finalised for more than one case, on the same date and in the same court level, their records are merged, and they are counted as one finalised defendant
  • Where a defendant is finalised for more than one case, on separate dates within the reference period, they will be counted once for each date they were finalised
  • Where a defendant is finalised in the Magistrates' Courts whilst other charges are committed to, and finalised in the Higher Courts, they will be counted once for each court level they were finalised in during the reference period

Transfers

The following counting rules apply with regards to defendants transferred from, or between court levels:

  • Defendants transferred from one Higher Court level to another Higher Court level (for example from a County Court to Supreme Court) are considered as finalised only once (from the level they finally left)
  • Defendants transferred from a Magistrates' Court or Children’s Court to a Higher Court (or vice versa) are considered as finalised twice (once in each of the courts)
  • Defendants transferred from the Magistrates' or Children's Courts to Specialist Courts for finalisation (e.g. Drug Courts) are considered finalised (by transfer) in the criminal court that initiated the transfer. Defendants may then, upon completion of the program, return to the court that requested the transfer, for an additional finalisation

From 2019–20 onwards, transfers to other court levels are excluded from defendant counts in most tables to avoid double-counting of defendants who were transferred and subsequently adjudicated in a different court level. Excluding transfers enables a more accurate representation of defendant characteristics, particularly for more serious offences where transfers to a Higher Court are more common.

Data items

Defendants who were finalised for more than one offence will have counting rules applied to determine their principal method of finalisation, offence, sentence type and other characteristics for inclusion in data tables.

Age

The age presented in the Criminal Courts data refers to the age (in years) of defendants at the time of case finalisation. It is not the age at which the defendant committed the offence. 

Sex

The categories used for defendant sex are: male, female, organisations, other and unknown. The number of defendants in the category of ‘other’ is currently not published due to small numbers and inconsistent use, though these defendants are included within the total. 

Indigenous status

This publication presents data on the Indigenous status of defendants finalised in New South Wales, Queensland, South Australia, Tasmania, the Northern Territory and the Australian Capital Territory. Based on ABS assessment, Indigenous status data for Victoria and Western Australia are not of sufficient quality and/or did not meet the ABS Indigenous Status Standard required for inclusion in national reporting. The ABS continues to work towards improving the quality and coverage of Indigenous status data for this collection.

Indigenous status data are generally based on information collected and recorded by police and transferred to courts systems (upon defendant initiation in the courts). The police information is based upon self-identification by the individual (or via a response from next of kin/guardian). As such, the quality of the Indigenous status data presented in this publication is dependent on police seeking and recording this information, and whether it can be transferred to the courts administrative systems.

In the Australian Capital Territory, defendants identified as non-Indigenous (from police data) are combined with defendants with unknown Indigenous status in Courts systems. Therefore, data for this jurisdiction (available from 2021–22) are presented together in a ‘non-Indigenous and not stated’ category.

Defendants in court for traffic offences often do not have Indigenous status information recorded due to these offences usually being dealt with by road traffic authorities. As such, Dangerous or negligent operation of a vehicle (ANZSOC 2011 Subdivision 041) and Traffic and vehicle regulatory offences (ANZSOC 2011 Division 14) are excluded from Indigenous status tables and text.

Other offences actioned by prosecuting agencies other than police (and which may therefore have low quality Indigenous status information), include: Public order offences (ANZSOC 2011 Division 13), Offences against justice (ANZSOC 2011 Division 15), and Miscellaneous offences (ANZSOC 2011 Division 16). This should be considered when comparing the Indigenous status of defendants for these offence categories.

Court levels

Data are reported at three court levels: Higher Courts, Magistrates’ Courts, and Children’s Courts.

In this publication, the Higher Courts comprises the Supreme and Intermediate Courts. All states and territories have a Supreme Court that deals with the most serious criminal matters, generally referred to as indictable offences (e.g. murder, manslaughter, serious sexual offences, assault, drug trafficking, robbery). The larger states (New South Wales, Victoria, Queensland, South Australia and Western Australia) also have an intermediate level of court, known as the District Court or County Court, which deal with most serious offences. All defendants that are dealt with by the Higher Courts have an automatic entitlement to a trial before a judge and jury. In some states and territories, the defendant may elect to have their matter(s) heard before a judge alone. Children treated as adults by the court may be included in the Higher Courts defendant counts.

The lowest level of Criminal Court is the Magistrates’ Court (also known as the Court of Summary Jurisdiction, Local Court or Court of Petty Sessions) which hears most criminal cases. Cases heard in the Magistrates’ Courts do not involve a jury – rather, a magistrate determines whether the defendant is guilty or not guilty. Children treated as adults by the courts may also be finalised in the Magistrates' Courts.

Each state and territory have Children's Courts to deal with offences alleged to have been committed by a child or juvenile. These courts mainly hear summary offences but do have the power to hear indictable offences in some states and territories. Defendants are considered a child if aged under 18 years at the time they committed an offence. Prior to February 2018, defendants in Queensland courts were considered to be a child only where they were aged under 17 years. 

A person can only be charged with a criminal offence if they are aged 10 years or over. The Northern Territory and the Australian Capital Territory lifted the minimum age of criminal responsibility to 12 years during the reference period, in August and November 2023 respectively. However, the Northern Territory has since lowered the age to 10 years again following the reference period of this release (in October 2024). Most states are also reviewing the minimum age of criminal responsibility, with a rise in age possible in future.

Principal offence 

Principal offence refers to the most serious offence (based on the ANZSOC) associated with a finalised defendant. For defendants finalised with a single offence type, this is their principal offence.

Where a defendant has multiple charges, their principal offence is determined using a multi-step process. The first is to code the outcome for each offence to a method of finalisation group and ranked as follows:

  • Defendant deceased, unfit to plead, or not guilty by reason of mental illness
  • Charges with a guilty outcome
  • Charges not proven
  • Transfer of charges to other court levels
  • Charges withdrawn
  • Other non-adjudicated finalisation
  • Unknown/not stated

The charge with the highest ranked method of finalisation group is allocated as the principal offence.

If there are multiple charges with the same method of finalisation group, the offence with the most serious sentence (based on the Sentence type classification 2023) is allocated as the principal offence. If multiple charges received the same sentence type, the offence with the greatest sentence length/amount is allocated as the principal offence.

The National Offence Index (NOI), which ranks offences according to perceived seriousness, is used to select the principal offence where there are multiple charges with the same method of finalisation group, sentence type and sentence length/amount.

For example, for a defendant with guilty outcomes for assault receiving a three-month sentence to custody in a correctional institution, and import of illicit drugs receiving a nine-month sentence to custody in a correctional institution, the principal offence would be import of illicit drugs. This is different from the methodology previously used, where the principal offence would be assault. Any charges for the same defendant that were withdrawn or not proven would not be considered.

For 2017–18 and prior years, the principal offence was based on the method of finalisation and NOI only. 

Method of finalisation

Method of finalisation refers to how a charge is concluded by a criminal court. For defendants who had multiple charges with varying outcomes, the method of finalisation is assigned based on the following order of precedence:

  • Defendant deceased
  • Unfit to plead
  • Not guilty by reason of mental illness/condition
  • Guilty finding by court
  • Guilty outcome n.f.d.
  • Guilty plea by defendant
  • Guilty ex-parte (Magistrates’ Courts and Children’s Court only)
  • Agreement of wrongdoing
  • Acquitted by court
  • Guilty outcome n.f.d.
  • No case to answer at committal (Magistrates’ Courts and Children’s Court only)
  • Charge unproven n.e.c.
  • Committed for trial (Magistrates’ Courts and Children’s Court only)
  • Committed for sentence
  • Transfer between court levels
  • Transfer to non-court agency
  • Withdrawn by the prosecution
  • Other non-adjudicated finalisation n.e.c.
  • Unknown/not stated

Principal sentence 

A sentence is a penalty or order imposed by a court upon a defendant who has a guilty outcome for a criminal offence.

Defendants can receive:

  • A single sentence for a single offence with a guilty outcome
  • A single sentence for multiple offences with a guilty outcome
  • Multiple sentences for a single offence with a guilty outcome
  • Multiple sentences for multiple offences with a guilty outcome

Defendants with more than one sentence type (for either a single offence or multiple offences) are assigned a principal sentence, which is intended to reflect the most serious sentence based on the hierarchy of the Sentence type classification 2023.

Compound (or ‘complex’) sentences can be broadly defined as sentences served in the community, that include various components or conditions, such as program attendance, community work, drug or alcohol treatment, counselling and education. These sentences are becoming increasingly common across states and territories due to their flexibility, with judges/magistrates able to tailor a sentence to suit the circumstances of an offender and their offending, whilst providing for both restitution and rehabilitation.

The Sentence type classification 2023 has been designed to reflect the severity of compound sentences, and improve comparability of sentences within and across states and territories. The components or conditions imposed within each compound sentence are considered when coding to the classification, so that sentences of a similar nature and level of severity are categorised together, regardless of the label of the order.

From 2022–23, data has been coded according to this approach and historical data for the years prior were approximated to the new classification. The application of the new classification has, for several jurisdictions, resulted in changes to the coding of some sentence orders. Refer to Data comparability – State and territory notes for more detail. 

Sentence length and fine amount

The sentence length and fine amount data presented in this publication represents the most severe penalty dealt to a defendant with a guilty outcome. This is determined using the Sentence type classification 2023 and the largest sentence length, or fine amount dealt for that sentence.

The following rules are applied in specific circumstances:

  • For sentences with terms to be served concurrently (commencing at the same time) or cumulatively (one after the other), the sentence length or fine amount is the largest value associated with the principal sentence and so may not represent the full penalty served by the defendant for all offences.
  • For terms of imprisonment, the sentence length presented is the total period of the sentence imposed, not the 'minimum sentence' or non-parole period. The reported sentence length for 'custody in a correctional institution' usually includes time already served in custody on remand.
  • Sentence length data for partially suspended sentences reflects the full period (i.e. the period suspended and the period in custody).

Where a single sentence is given for multiple offence types (or multiple instances of a single offence type) this may result in an overstated sentence length or amount for the associated offence, that is, the value is actually imposed on more than the principal offence it is associated with.

Life and indeterminate sentences do not have a determined term and are excluded from mean and median sentence length calculations. However, from 2019–20, defendants with these sentences are counted within the category of ‘10 years and over’ for length of time sentenced to custody in a correctional institution.

Duration

Duration is a measure of court timeliness. It represents the time taken (in days) between the date a defendant’s case(s) was initiated in court (through committal or registration) and the date they ceased to be an item of work for the court as follows:

Duration = Date of finalisation – Date of initiation + 1

Rate of defendants finalised

The (crude) rate of defendants finalised is expressed as the number of defendants (excluding organisations) per 100,000 of the ABS Estimated Resident Population (ERP), for persons aged 10 years and over. The ERP used in these calculations are based on the mid-point of the relevant reference period (e.g. 31 December 2023 for the 2023–24 reference period). Rates presented by sex and age are based on ERP for the relevant sex or age group.

The ERP used for 2021–22 to 2023–24 rates are from preliminary population estimates released for each year in National, state and territory population (reference periods December 2021, December 2022 and December 2023 respectively). For 2020–21 rates and earlier, final population estimates have been used.

Rates of Aboriginal and Torres Strait Islander defendants are expressed per 100,000 of the Aboriginal and Torres Strait Islander population aged 10 years and over. The population used in these calculations are approximated from the mid-point between each 30 June estimate for 2016 to 2021, and from the medium assumption series projections for 2022 onwards (in Estimates and Projections, Aboriginal and Torres Strait Islander Australians, 2011 to 2031). 

Rates by Indigenous status are not included prior to 2016–17 in this release. Further work is required to determine an appropriate series of Aboriginal and Torres Strait Islander historical population estimates for comparative rates. For more information about this issue, please refer to the ABS article Guide to using historical estimates for comparative analysis and reporting

Rates for the non-Indigenous population are calculated using the total ERP for persons aged 10 years and over for the relevant state or territory, minus the projected Aboriginal and Torres Strait Islander population aged 10 years and over. 

Both the ERP estimates and projections used in this release exclude Christmas Island, Cocos (Keeling) Islands, Jervis Bay Territory and Norfolk Island.

In addition to crude rates, age standardised rates have been included to account for age differences between the Aboriginal and Torres Strait Islander and non-Indigenous populations, with the former having a larger proportion of their ERP aged between 10–29 years. Due to the differing age profiles, using crude rates to examine differences between Aboriginal and Torres Strait Islander and non-Indigenous defendants may lead to erroneous conclusions being drawn about variables that are correlated with age.

Age standardisation removes age-related differences from rates by standardising to a single age profile that is common to both populations. The standard population used for age standardisation is the total Australian ERP as at 30 June 2001. The standard population is revised every twenty-five years with the next revision to be based on final estimates from the 2026 Census of Population and Housing.

Age-standardised rates should be used when comparing rates between the Aboriginal and Torres Strait Islander and non-Indigenous populations for the same state or territory. Crude rates should be used for all other purposes, for example, comparisons of rates between states and territories for the Aboriginal and Torres Strait Island population or for the non-Indigenous population. 

Only the crude rate of defendants finalised is reported for the ACT Aboriginal and Torres Strait Islander population as the rate for the ACT non-Indigenous population is not available for comparison. 

Revisions in this release

Aboriginal and Torres Strait Islander rates and non-Indigenous rates have been revised from 2016–17 to 2022–23, using new estimates and projections of the Aboriginal and Torres Strait Islander population based on the 2021 Census. 

Data release

Classifications

Classifications provide a framework for organising and presenting data in a comparable and consistent manner. The key classifications used for this collection are:

ANZSOC 2011

Offence data are presented according to the Australian and New Zealand Standard Offence Classification (ANZSOC), 2011.

For ease of reading, some ANZSOC 2011 offence names have been abbreviated throughout this publication as follows:

  • Dangerous or negligent acts endangering persons appear as 'Dangerous/negligent acts'
  • Abduction, harassment and other offences against the person appear as 'Abduction/harassment'
  • Robbery, extortion and related offences appear as ‘Robbery/extortion’
  • Unlawful entry with intent/burglary, break and enter appear as 'Unlawful entry with intent'
  • Theft and related offences appear as ‘Theft’
  • Fraud, deception and related offences appear as ‘Fraud/deception’
  • Prohibited and regulated weapons and explosives offences appear as 'Weapons/explosives'
  • Offences against justice procedures, government security and government operations appear as 'Offences against justice'
  • Child pornography is also referred to as child abuse material offences. 

ANZSOC 2023

Preliminary offence data are presented according to the Australian and New Zealand Standard Offence Classification (ANZSOC), 2023. Additional information relating to the differences between ANZSOC 2011 and ANZSOC 2023 can be found in the section on Preliminary ANZSOC 2023 data.

Method of finalisation

Method of finalisation refers to how a criminal charge is concluded by a criminal court. The Method of finalisation classification contains the main categories of:

  • Adjudicated finalisation – a judgement or decision by the court as to whether or not the defendant is guilty of the charge(s) against them
  • Non-adjudicated finalisation – a charge(s) considered to have been completed even though a judgement has not been handed down by the court (e.g. withdrawn by the prosecution, defendant deceased, unfit to plead, or transfers to non-court agencies)
  • Transfers to other court levels – a court order for the criminal charge(s) to be transferred to another court level for adjudication or sentencing

Sentence type

The Sentence type classification 2023 describes the types of sentences that are handed down by the court for offences with a guilty outcome, and includes the main categories of:

  • Custody in a correctional institution
  • Intensive penalty in the community
  • Fully suspended sentence of imprisonment
  • Community service/work
  • Moderate penalty in the community
  • Monetary orders (largely fines)
  • Good behaviour (incl. bonds)
  • Nominal and other penalties

The previous Sentence Type Classification was used for releases prior to 2022–23. However, earlier data has been transitioned to the new classification structure, where possible, to provide time series comparability. 

In some cases, defendants with a method of finalisation of 'Not guilty by reason of mental illness/condition' may have a type of order imposed. However, these sentences are not published for this collection.

Confidentiality

The Census and Statistics Act 1905 provides the authority for the ABS to collect statistical information, and requires that statistical output shall not be published or disseminated in a manner that is likely to enable the identification of a particular person or organisation. To minimise the risk of identifying individuals in aggregate statistics, perturbation has been applied to all data presented in this publication, to randomly adjust cell values and summary variables. This technique involves small, random adjustment of the statistics and is considered the most satisfactory technique for avoiding the release of identifiable statistics while maximising the range of information that can be released. These adjustments have a negligible impact on the underlying pattern of the statistics.

The result of perturbation is that a given published cell value will be consistent across all tables, but the sum of the components of a total will not necessarily be the same as the published total. As such, proportions may add to more or less than 100%. Readers are advised to use the published totals rather than deriving totals based on the sum of component cells. Cells with small values may be proportionally more affected by perturbation than large values. Users are advised against conducting analyses and drawing conclusions based on small values.

Data comparability

State and territory notes

Every state and territory has their own courts systems that operate under state and territory laws, determined by state and territory governments, that are largely independent of each other. 

National standards and classifications are used to produce nationally comparable data. However, various factors can impact data quality and comparability, including:

  • Data systems being designed for the purpose of administration of court business (as opposed to national statistical purposes)
  • Modification to data systems and methodology used to extract/compile data
  • Refinements to data quality procedures
  • Legislative or operational differences (such as differences in the types of sentencing options available to the courts)

New South Wales

Dates of initiation for the Magistrates’ and Children’s Courts are based on the date of first appearance rather than the date of registration, as the latter is not captured by the NSW Bureau of Crime Statistics and Research. As such, the median duration in New South Wales Magistrates’ and Children’s Courts may be lower than other states and territories. This issue does not impact the Higher Courts data.

In January 2022, the New South Wales Police Force made it mandatory to ask all persons of interest and victims of crime if they identify as Aboriginal and/or Torres Strait Islander, excluding incidents where a traffic, marine or transport infringement was issued. This has had a positive effect on the quality of data on Indigenous status in this collection, reducing the level of unknowns from 15% of applicable defendants in 2021–22 to 8% in 2022–23. This should be taken into account when comparing statistics relating to Aboriginal and Torres Strait Islander defendants in New South Wales over time.

With the introduction of the new Sentence Type Classification, from 2022–23 fully suspended sentences with supervision under Children’s Court and Commonwealth legislation are coded to Intensive custody in the community. In addition, under the new classification rules, some community orders including Good behaviour orders with conditions are coded to Moderate penalty in the community where appropriate.

New South Wales legislation does not contain discrete offences of stalking and harassment (as per ANZSOC 2011 categories), and so all such offences are coded to ANZSOC 2011 Group 0291 Stalking (in Division 2 Acts intended to cause injury). Therefore, Stalking offences are likely to be overstated and Harassment and threatening behaviour understated (in ANZSOC 2011 Division 05 Abduction/harassment).

Drink and drug driving reforms were implemented in New South Wales in May 2019 as part of the Road Safety Plan 2021. Drivers with first-time low-level drink driving and drug-presence offences can be dealt with through an infringement notice process instead of being processed through the courts, reducing the number of fines issued by the New South Wales courts.

Sentence reforms were introduced in New South Wales in September 2018. Intensive correction orders were changed, making supervision mandatory and allowing for a range of conditions to be imposed, including home detention and community service work. Suspended sentences were repealed, as were home detention and community service orders as individual sentences. Good behaviour bonds and non-conviction bonds were also repealed, replaced by community correction orders and conditional release orders. These changes contributed to noticeable increases in intensive penalty in the community and moderate penalty in the community, and noticeable decreases in fully suspended sentences, fines and orders of good behaviour.

The Table Offences Reform involved reclassifying some strictly indictable offences (matters that must be dealt with by the Higher Court) as 'Table offences' that can be dealt with in the local court. The first tranche implemented in November 2016 involved a subset of 'break and enter' offences. The second tranche was implemented in two phases: in April 2018 (a subset of theft offences) and July 2018 (a subset of robbery and illicit drug offences). Analysis of the impact of both tranches of Table Offences Reform show that reclassifying offences from strictly indictable to Table offences reduced the number of matters finalised in the District Court and court duration, and decreased the number of longer custodial sentences.

The Early Appropriate Guilty Plea reform was implemented in New South Wales in May 2018. This reform was employed to encourage defendants to plead guilty earlier in the process through the introduction of structured behavioural incentives. This increased the proportion of cases committed to the Higher Court where a guilty plea had been entered in the Local Court, and has reduced the overall duration of cases in the Higher Courts.

In September 2017, the Judicial Commission of New South Wales reclassified a number of local Law Part codes to different ANZSOC 2011 codes to improve data quality – most notably, knife offences under the Summary Offences Act, 1988. These updates were backcast to several ANZSOC 2011 categories from 2015–16, most notably leading to an increase in the number of defendants with a principal offence of ANZSOC 2011 Division 11 Weapons/explosives, and a decrease in both ANZSOC 2011 Division 13 Public order offences and Division 16 Miscellaneous offences.

Victoria

In the Children’s Courts, community service can be ordered as part of a youth attendance order or youth supervision order. However, the community service component of these orders is recorded as a free text field in the data management system and is therefore not able to be extracted for inclusion in the Victorian Children’s Courts sentencing data. Therefore, counts of Community service in the Children’s Courts are understated, and moderate penalty in the community is overstated. 

From 2022–23, following a review of coding to the new Sentence Type Classification, Youth Supervision Orders have been coded to Moderate penalty in the community, instead of Intensive penalty in the community.

Prior to 2021–22, ancillary orders made with an adjournment order were incorrectly included as an ‘Other non-custodial sentence n.e.c’. Finalised defendant counts in these Courts were therefore overstated in previous years by around 1% in the Magistrates’ and 2-3% in the Children’s Courts.

In Victoria, defendants with an outcome of ‘Guilty finding’ by the Children's Court are undercounted due to difficulties in reporting. The method of finalisation for these defendants is coded as a 'Guilty outcome, not further defined'.

The commencement of the Fines Reform Act in December 2017 saw a substantial change in legislation which governs how an infringement matter is commenced in the Magistrates’ Courts. This has resulted in a decrease in defendants finalised in the Magistrates’ Courts, particularly for traffic offences from 2017–18 onwards.

In January 2017, the Victorian Children’s Courts rolled out a state-wide Children’s Courts Youth Diversion service, following a 12-month pilot. The diversion program is targeted at young people who are charged with low level offences, have little or no criminal history, and who would otherwise have been sentenced to an outcome not requiring supervision. This contributed to a decrease in defendants finalised in the Children’s Courts during 2017–18, impacting age, duration and principal sentence data.

From 2016–17, offences against the Eastlink Project Act have been coded to ANZSOC 2011 group 1439 Regulatory driving offences. Prior to this, these offences were coded to ANZSOC 2011 group 1311 Trespass.

For all years prior to 2016–17, the number of defendants acquitted in the Victorian Magistrates’ and Children’s Courts are overstated, while those with a guilty outcome and sentenced to a nominal penalty are understated. This resulted from both outcome types being recorded as ‘dismissed’ on the Victorian Court link system and thereby coded to a method of finalisation of acquitted within the historical Criminal Courts data.

From September 2013, suspended sentences ceased to be a sentencing option in the County and Supreme Courts (Higher Courts) in Victoria, and in the Magistrates’ Courts in September 2014. This resulted in a decrease in these sentences from 2014–15 and increases in other principal sentence types.

In January 2012, changes to the Sentencing Act removed the Victorian Courts’ ability to impose the following sentences: community-based orders, intensive corrections orders, combined custody and treatment orders or home detention orders. These were replaced by a new community correction order (CCO) which can contain multiple conditions. In 2012–13, the order was originally mapped only to community service orders, but from 2013–14 more detailed sentence information was provided, which enabled the coding of this sentence according to the conditions. This resulted in an increase in defendants with a principal sentence of community service order, intensive penalty in the community, and moderate penalty in the community.

Queensland

In May 2024, the Queensland Police Drug Diversion Program, which provides an alternative to prosecution, was expanded to include the minor possession of all types of drugs. The expansion of this program is likely to have contributed to the decrease in offenders with a principal offence in ANZSOC 2011 Division 10 Illicit drug offences from 202324.

In February 2018, the Youth Justice (Transitional) Regulation commenced, with the age range for the youth justice system including 17 year olds, who had previously been included within the adult justice system. These changes resulted in defendants being transferred from the Magistrates’ to Children’s Court during 2017–18, and a subsequent increase in defendants finalised in the Children’s Courts during 2018–19.

In Queensland, a defendant can elect to have a summary offence transferred to the Higher Courts (with the consent of the court), where they have also been charged with an indictable offence in the same incident, so the matter(s) can be sentenced at the same time. For the 2017–18 release of this publication, these types of transfers were included in Queensland data for the first time, following improvements to administrative systems. This resulted in an increase in transfers from Magistrates’ Courts to Higher Courts for Queensland during 2017–18.

South Australia

In 2022–23, the South Australian Courts Administration Authority introduced a new case management system. This is expected to have improved the consistency and quality of data recording, and reduced the number of duplicated defendant records by consolidating relating cases (such as where charges have been changed and re-laid) into one. This is likely to have affected the number of finalised defendants.

Further, the new system supported detailed coding to the new Sentence Type Classification, and Good behaviour orders with conditions have since been coded to Community service and/or Moderate penalty in the community, as appropriate. 

It was identified that the process for transferring SIQ (Standard Indigenous Question) indicators through the SA Police data management system to the court system was affected in instances where the information was manually entered as a new case instead of using the Police Case Number, causing SIQ answers to be understated. This affects all data for years up until 2020–21. 

Prior to 2020–21, defendants who had a guilty outcome, but received no sentence or a nominal sentence due to time already served on remand, were being coded as receiving a nominal penalty. To better reflect their experience and improve comparability, from 2020–21, these sentences have been coded as a type of custody in a correctional institution (with no sentence length available). Following the introduction of the new sentence classification in 2022–23, these sentences have been separately output as ‘No further penalty due to time spent in custody’.

From 2019–20, cases that are dismissed by the judiciary are coded as ‘Charge unproven n.e.c.’ where they were previously coded as ‘Withdrawn by prosecution’. This contributed to a decrease in cases reported as withdrawn and corresponding increase in cases reported in the broader category of ‘Acquittals’.

In November 2018, the SAPOL Shield data management system was introduced by South Australia Police. This led to some changes in data collection that may impact data movements.

In March 2018, the Summary Procedure (Indictable Offences) Amendment Act 2017 was enacted. This led to a number of changes which contributed to an increase in case duration and fewer cases heard in the Higher Courts.

From December 2016, the introduction of adult cautioning by South Australia Police reduced the number of court lodgements of minor criminal matters, including matters that would have been heard and determined by Special Justices, and those heard in the Early Resolution Court (which has ceased to operate). As a result, there were notable decreases in the number of defendants finalised for minor criminal matters (such as traffic and vehicle regulatory offences) and in associated duration information, in the 2017–18 data.

In 2016, the Statutes Amendment (Home Detention) Act, 2016 established home detention as an alternative to a sentence of custody in a correctional institution for selected offences heard by the Magistrates’ Court. This led to an increase in defendants sentenced to an intensive penalty in the community from 2016–17.

In February 2014, the Statutes Amendments (Fines Enforcement and Recovery) Act 2013 came into effect causing a decrease in the number of finalised defendants from 2014–15 onwards. The Act transferred responsibility for the collection and enforcement of fines from the Courts Administration Authority to the Fines Enforcement and Recovery Unit (managed by the South Australian Attorney-General’s Department). This resulted in decreases in defendants finalised, particularly those with a combination of guilty ex-parte finding, a principal offence of ANZSOC 2011 Division 14 Traffic and vehicle regulatory offences, and a principal sentence of a fine.

In 2013–14, changes were made to how sentence length was determined for partially and fully suspended sentences, to align with national standards. Prior to this, only the imprisonment portion was included for partially suspended sentences, and for fully suspended sentences the good behaviour bond component was supplied (which was often longer than the suspended jail term). These changes resulted in increased sentence lengths for partially suspended sentences, and decreases for fully suspended sentences in 2013–14.

Western Australia

The implementation of the new Sentence Type Classification in 2022–23 better reflects the nature and severity of the sentencing conditions imposed, which for Western Australia, resulted in an increase in defendants sentences to intensive penalty in the community, and associated decrease in community service and moderate penalty in the community. 

From 2012–13, all components of compound sentences have been provided to the ABS, making it possible to derive a more accurate principal sentence. This resulted in an increase in principal sentences of community service orders and a decrease in low intensity supervision. 

From 2013–14 onwards, date of initiation for the Magistrates' and Children's Courts is based on date of registration (as per national reporting standards). Previously, the date of first appearance was provided for the calculation of case duration.

Tasmania

Tasmania police data is stored on multiple systems and Indigenous status is not consistently recorded, so coverage is inadequate for publication in ABS recorded crime statistics. However, of those defendants subsequently heard in Criminal Courts, a sufficient proportion had their Indigenous status recorded, and subsequently this data has been published from 2021–22 onwards. Consideration should be given to the proportion of defendants with an unknown Indigenous status in any subsequent analysis.

Prior to 2020–21, courts fees and levies were coded to monetary penalties. For national consistency, coding for these fees and levies was shifted to Nominal penalties. This resulted in an associated increase in Good behaviour orders as these co-occurring sentences became the principal sentence.

In 2019–20, some fully suspended sentences in the Higher Court were incorrectly recorded as ‘custody in a correctional institution’. The 2020–21 release included revised 2019–20 data that resolved this issue.

A review of finalisation methods in 2019–20 led to an increase in defendants finalised as ‘charges not proven n.e.c.’ (acquitted) where previously they were classified as ‘withdrawn’.

From 2019–20, offences of ‘Possess dangerous article in a public place’ are included in ‘Weapons/Explosives’, where they were previously coded to ‘Dangerous or negligent acts’.

Tasmanian Higher Courts sentence length and fine amount data became available in 2018–19. However, sentence length data for good behaviour bonds remain unavailable for the Higher Courts.

In December 2018, the Sentencing Act 1997, introduced new alternatives to suspended sentences such as Home Detention (included under ‘Intensive penalty in the community’) and community correction orders (included under ‘community service/work’ or ‘moderate penalty in the community’ depending on the conditions imposed).

In 2017–18, the Tasmanian Police Prosecutions undertook a clearing of their case backlog. This resulted in a large increase in the number of defendants who had matter(s) referred to (and finalised in) the Magistrates’ Courts over the period, leading to an increase in cases acquitted or withdrawn.

During 2014–15 and 2015–16, a number of archival cases were closed in the Magistrates’ Court system, with these defendants finalised as ‘charges not proven, not elsewhere classified’. This resulted in increases in the method of finalisation of acquitted, and duration data.

Northern Territory

From March 2024, significant sentencing reform in the Northern Territory changed the penalties able to be issued. With the introduction of Community Corrections Orders and Intensive Community Correction orders, there has been an associated increase in defendants with a principal sentence of Moderate penalty in the community and Intensive penalty in the community respectively, and a decrease in Good behaviour orders.

During 2023–24, a new integrated case management system, ‘SerPro’, was introduced. While the transition represented a significant change for the police and courts sectors, the data for 2023–24 appears to be largely comparable to previous years.

In August 2023, the Northern Territory raised the minimum age of criminal responsibility from 10 to 12 years of age. This reduced the number of very young defendants finalised in the Children’s Courts during the reference period. However, the Northern Territory has since lowered the age to 10 years again following the reference period of this release (in October 2024).

In 2023–24, there was an improvement in coding of offences of driving causing death which has resulted in an increase in defendants with a principal offence of ANZSOC 2011 group 0132. However, there remains some instances where driving causing death cannot be separately identified from driving causing grievous bodily harm, so ANZSOC 2011 group 0412 ‘dangerous or negligent operation of a vehicle’ is overstated, and ANZSOC 2011 group 0132 ‘driving causing death’ is understated.

Unlike other states and territories, the date of initiation in Magistrates’ and Children’s Courts in the Northern Territory is based on the earliest of the date the case was filed, the date the case was created, or the date of first appearance. This affects the calculation of duration data.

In the Northern Territory, defendants with an outcome of  ‘Guilty finding by court’ are understated in the Magistrates’ and Children’s courts, due to inconsistent capture of defendant plea during data entry.

From 2018–19, payment of court costs/levies are categorised as a sentence type of nominal penalty, rather than ‘other monetary orders, not elsewhere classified’ to align with national standards.

From March 2016, police in the Northern Territory issued on-the-spot fines for long-term unlicenced and unregistered drivers. These were offences previously dealt with by the courts. This resulted in a decrease in defendants with a principal offence in ANZSOC 2011 Division 14 Traffic and vehicle regulatory offences in 2016–17. 

In 2012, magistrates started to hear minor matters ex-parte (instead of issuing bench warrants) if the defendant did not appear for the court hearing. This resulted in an increase of guilty ex-parte finalisations from 2011–12.

In 2011–12 and 2012–13, a joint project was undertaken between the Northern Territory Department of the Attorney-General and Justice and police to clear up historic outstanding warrants and summons matters. This resulted in increases in the number of finalisations, duration, cases withdrawn by the prosecution, and defendants with unknown Indigenous status during these time periods.

Australian Capital Territory

Following the payment of infringement notices, traffic-related offences have generally been dismissed by the Magistrates’ Court and counted by the ABS as ‘Acquitted’, which was responsible for noticeable levels from 2019–20. In 2023–24, changes to Road Transport Authority processes resulted in some of these traffic-related offences being withdrawn by the prosecution instead.

Defendants with voting offences in 2021–22 experienced a relatively high rate of acquittals, with many cases dismissed following payment of infringements.

During 2021–22, there was a spike in defendants charged with ‘failure to vote’ (ANZSOC 2011 Group 156 Offences against justice procedures), following the general election in late 2020. The majority of these defendants did not have their Indigenous status recorded in the Criminal Courts data.

The ACT relies on data from third party prosecuting agencies (such as the National Capital Authority and the Australian National University) many of which do not require and/or allow for the recording of defendant sex or date of birth. These bodies are not managed by ACT Courts, and as a result, the ACT has a substantially higher proportion of defendants with an unknown sex compared to other states and territories.

In 2018–19, ACT Courts records were migrated to the Integrated Court Management System. This improved the ability to incorporate external data, reducing the number of duplicated defendant records and consolidating related cases into one. This is likely to have affected the number of finalised defendants.

From 2018–19, a review into the coding of court fees and levies resulted in a reduced number of defendants with a principal sentence of a ‘fine or other monetary order’ in line with the ABS coding requirements to exclude such fees.

In 2014–15, amendments were made to offence coding in order to improve comparability with the other states and territories. Most notably, driving offences that did not result in a fatality (previously coded to ANZSOC 2011 Group 0132 Driving causing death) were remapped to ANZSOC 2011 Group 0412 Dangerous or negligent operation of a vehicle.

Changes to multiple states and territories

Conference or diversion programs

The Children’s Courts in each state and territory offer diversionary programs to eligible defendants. These diversionary programs or conferences often include requirements of an apology, reparation and/or behaviour management programs.

In Queensland, a diversion program can be ordered as the sentence for a youth defendant with a guilty outcome and have previously been coded to Sentence type 840 ‘Referral to conference’. However, in most states and territories, diversion programs are undertaken during the court process, after the defendant has agreed to their wrongdoing (not necessarily considered a formal guilty plea), with successful completion usually resulting in the charges being withdrawn or dismissed and no further penalty imposed. 

To ensure that diversion programs are able to be separately presented in national statistics as the ‘penalty’ served by the youth defendant, new classification categories and coding rules have been introduced from 2023–24.

From 2023–24, a new Method of finalisation for ‘Agreement of wrongdoing’ is available, and the number of youth defendants either sentenced to or agreeing to attend a ‘Conference or diversion program’ (regardless of whether it was completed) is available for principal sentence data. For New South Wales, the count represents defendants completing a diversion, and where it was not completed they will be counted under their subsequent sentence. 

The number and proportion of defendants in each state or territory commencing a diversion from the Children’s Court should also be considered in the context of diversionary options utilised prior to court (such as initiated by police). 

The changes to improve national consistency in recording of diversions will have the following affects on state and territory data:

  • New South Wales, Victoria and Tasmania previously recorded Children's Courts defendants undertaking a diversion as having a guilty outcome and sentenced to a ‘Nominal penalty’ (or other various sentence types in Tasmania)
  • South Australia and Western Australia previously recorded Children’s Courts defendants undertaking a diversion as being transferred to a non-court agency 

In the Australian Capital Territory and the Northern Territory, Children’s Courts can utilise diversion programs for eligible youth defendants, but this information is currently not able to be separately presented in ABS data.

Other changes or issues

From March 2020 onwards, Australia’s federal, state and territory governments put restrictions in place in response to the COVID-19 pandemic. These restrictions led to a decrease in the number of defendants finalised due to the deferral of courts cases, and indirect impacts such as reduced motor vehicle use. Decreases in particular offence types contributed to overall changes in method of finalisation, sentence and duration. Increases in defendant numbers in later years may be due to rates of offending, but also delayed processing of older, pending cases.

From 2014–15, drug driving offences relating to the Road Traffic Act 1961 section 47BA, have been coded to ANZSOC 2011 group 0411 Driving under the influence of alcohol or other substances. Prior to this, these offences were coded to ANZSOC 2011 group 1431 Exceed the prescribed content of alcohol or other substance limit. This change affected Victoria, Queensland, South Australia and Western Australia. 

Comparisons to other data

ABS crime and justice data

Some broad comparisons of data in this collection with other ABS crime and justice collections can be made e.g. basic demographics or overall trends in offence types. For example, courts data can be broadly compared with the number of court-initiated police proceedings (refer to Recorded Crime – Offenders). However, the data in the two collections are not strictly comparable because: 

  • Not all court-related actions initiated by police will proceed to a criminal court (e.g. charges may be changed by police during the course of an investigation)
  • Prosecutions in a criminal court may be initiated by authorities other than police
  • Time lags occur between the police initiations (to court) and the finalisation of the defendant's matter(s) in court

Report on Government Services

The Report on Government Services (RoGS), produced by the Productivity Commission, provides information on the performance of Australian state and territory government services, including courts. The RoGS report provides some information that is comparable to this collection, with both using the same national classifications and standards.

However, the focus of the two collections differs. The Courts chapter in the RoGS focuses on the efficiency and effectiveness of the administration of the courts, including workload indicators and financial information. This publication focuses on the characteristics of finalised defendants (e.g. demographics, offences and sentences).

Both collections have the ‘finalised defendant’ as a counting unit. However, the RoGS collection defines a defendant as ‘a person with one or more charges and with all charges having the same date of registration’. In comparison, the ABS collection defines a defendant as ‘a person or organisation against whom one or more criminal charges have been laid and which are heard together as one unit of work by a court at a particular level’ and uses the ‘date of finalisation’. This difference means that the count of finalised defendants can be lower in the ABS collection when compared with RoGS.

Both the RoGS and ABS data contain measures of court timeliness. The ABS presents a ‘duration’ measure, while the RoGS presents the pending caseload count as at 30 June each year, and the proportion of cases by length of time pending.

Family and domestic violence statistics

The data presented in the Family and Domestic Violence (FDV) section are experimental, with further assessment required to ensure comparability and quality. Caution should be exercised when using the data and making comparisons across states and territories, and over time.

For this data, an FDV-related offence includes selected ANZSOC 2011 categories of Homicide and related offences (Division 01), Acts intended to cause injury (Division 02), Sexual assault and related offences (Division 03), Abduction/harassment (Division 05), Property damage (Subdivision 121), Breach of violence order (Group 1531), and Other dangerous or negligent acts (Subdivision 049). 

Additional data are also included relating to defendants who were finalised for an offence of FDV-related 'breach of violence order’.

This release presents experimental statistics about defendants finalised for at least one Family and Domestic Violence (FDV) offence (refer to ‘Definition’ below), in the Higher, Magistrates’ and Children’s Courts between 1 July 2023 and 30 June 2024.

Definition

There is no single nationally or internationally agreed definition of what constitutes ‘family and domestic violence’, and the terminology used to refer to ‘FDV behaviours’ varies across policy, legislative, service provision, and research contexts. Further, understandings of FDV continue to evolve, including the behaviours and/or relationship types that are considered to be familial or domestic in nature.

FDV can include a wide range of violent and non-violent abusive behaviours or threats, such as:

  • Physical and sexual violence or abuse
  • Emotional and psychological abuse
  • Verbal abuse and intimidation
  • Economic abuse
  • Social deprivation and controlling behaviours
  • Damage of personal property
  • Abuse of power

The types of relationships involved in FDV can include (but are not limited to):

  • Intimate partner relationships
  • Other family and co-habitation relationships
  • Siblings
  • Children
  • Carer relationships
  • Cultural and kinship relationships
  • Foster care relationships
  • Relatives who do not co-habit

Differences in the state and territory legislation used to determine the types of behaviours and relationships that constitute a family and domestic violence offence should be considered when interpreting data.

FDV data collection

The experimental FDV data published in this collection are based on information recorded in state and territory court administrative systems. FDV offences are largely identified by an indicator (or ‘flag’) that is recorded by either the police and/or courts, as follows:

  • In Victoria, South Australia, Western Australia, the Northern Territory and the Australian Capital Territory police officers flag FDV offences, following investigation/charging, on their crime recording systems. This is transferred through to courts administrative systems.
  • In New South Wales, Queensland and Tasmania, FDV offences are identified by FDV-specific legislation and are flagged either by police or when the matter is dealt with by the court.

Additional FDV offences may be identified through the offence description, or court hearing type, or if they are ordered to be flagged as FDV-related by the judiciary.

Substantial improvements in the identification of FDV offences have been made in several states in recent years, so increases in defendant counts may reflect this along with any real-world change.

Given these differences in how FDV offences are identified or defined, direct comparisons of the state and territory FDV data presented in this publication should not be made.

FDV data processing

Counting methodology

The principal counting unit for the experimental FDV data is a defendant who has been finalised for at least one FDV-related offence during the reference period.

Where a defendant has had multiple FDV offences finalised on the same date within the same court level, they will be counted once and assigned a principal FDV offence based on the method of finalisation, sentence outcome and the National Offence Index 2018 (NOI 2018). This is consistent with the counting methodology for the broader defendant population.

Non-FDV offences (i.e. those that are not flagged) are excluded from the data prior to determination of a defendant’s principal FDV offence. As such, principal FDV offence data are not directly comparable with principal offence data presented elsewhere in this publication.

In line with ABS policy on data confidentiality, table cells containing small values have been randomly adjusted through perturbation. As such, the sum of the components will not necessarily give the same result as the published total.

FDV-related breach of violence orders

The additional data on ‘FDV-related breach of violence orders’ is intended to inform the growing need for statistics relating to FDV in the national policy and service space. These data complement similar information included in Recorded Crime – Offenders.

Under usual methodology, the count of FDV-related breach offences appears understated because these offences are often heard alongside ‘more serious’ FDV-related offences (e.g. assault), which usually become the principal FDV offence for the defendant. 

Unlike other parts of this release where only principal offence is counted, the tables specific to FDV breach of violence orders includes all defendants who were finalised for this offence, regardless of any other offences for which they were also finalised at the same time. This presents a more complete picture of the number of FDV-related breach of violence order offences.

Users are advised against making state and territory comparisons of FDV breaches data due to the variations in policing and court practices.

FDV data comparability

The comparability of FDV data may vary across time periods – both within and across states and territories – due to a number of factors including:

  • Differences or changes in state and territory police/court operations and business rules
  • Differences in state and territory legislation with regard to the relationships and/or offences that are defined as FDV
  • Differences or changes in the reporting behaviour of victims
  • Improvements in the quality or availability of FDV data and flagging recorded on police and courts administrative systems

State and territory FDV-related notes

This section describes state and territory specific events or processes (e.g. recording practices or legislation changes) that may impact on the availability, and/or comparability of state and territory FDV data. The notes relating to the collection as a whole are also applicable to FDV data.

To address state and territory variation in the legislation and coding of harassment and stalking offences, these data have been combined for output in a category labelled ’stalking, harassment and threatening behaviour’.

New South Wales

In New South Wales, FDV offences can be identified either by the associated legislative reference, or when the courts make an order for the ‘Offence to be recorded as a domestic violence offence’. 

The flagging of offences against Commonwealth legislation can only be made by the courts through such an order. While this process is open to the courts, these orders are (currently) rarely applied to Commonwealth offences. From 2022–23, Commonwealth harassment offences are flagged as FDV-related if they occurred on the same date as a FDV-related breach of violence order. 

Victoria

In Victoria, when a Magistrates’ or Children’s Courts defendant attends court from custody, their records are initiated manually in the court recording system. As such, the FDV flag – which is recorded in the police system and transferred to the court system in automated case initiations – is not applied to these defendants’ court records. This results in a lower level of FDV flagging for certain offence types, in particular ANZSOC 2011 Divisions 01 Homicide and related offences and 03 Sexual assault and related offences. 

Queensland

While the most common FDV principal offence across the country is assault, in Queensland breaches of violence orders account for a greater proportion. This has been due to police operational differences, whereby in Queensland if there was an existing violence order, a breach of that order was recorded but the associated assault may not have been recorded. However, from 1 July 2021, Queensland police officers must record all criminal offences associated with an FDV incident. This has resulted in an increase in the number of defendants of FDV-related assault.  

South Australia

The transfer of FDV indicators from the SA Police data management system to the court system is incomplete where information for a new case is manually entered instead of using the Police Case Number, causing FDV cases to be understated. From 2021–22, additional methods of identifying FDV-related offences were introduced which has offset this and resulted in a substantial increase in counts of FDV defendants in South Australia. Users are advised to not compare data from 2021–22 to previous years.  

Western Australia

Information relating to FDV offenders is recorded by Western Australia Police on two separate crime recording systems: the Information Management System and the Prosecutions system. Only data from the Prosecutions system transfers through to the criminal courts administrative systems. As such, statistics about FDV defendants for Western Australia may be understated.

In 2023–24, an improvement in the identification of sexual assault offences as being FDV-related resulted in an increase in these counts, especially in the Higher Courts.

From 2021–22, additional breach of violence order offences have been identified as FDV-related, which resulted in an increase in FDV defendant counts in Western Australia. Users are advised to not compare data from 2021–22 with previous years.

Tasmania

Tasmanian data about defendants with FDV-related offences is only available for defendants for which the victim(s) are partner/spouse/husband/wife/boyfriend/girlfriend (including former). This is a narrower relationship scope than other jurisdictions, and users are cautioned in making comparisons between Tasmania and other states and territories.

Improvements during 2020–21 in the identification of family violence related offences in the courts, has resulted in a notable increase in the number of defendants with a FDV offence, in particular a breach of violence order. All offences against the ‘Family Violence Act’ are now flagged as FDV-related.

Preliminary ANZSOC 2023 data

During 2022–23, the ABS conducted a review of the Australian and New Zealand Standard Offence Classification. The review was designed to modernise the language, reflect changes that have occurred in criminal legislation, and respond to emerging user requirements for further detail in some areas. The Australian and New Zealand Standard Offence Classification (ANZSOC), 2023 was released in November 2023.

From the ANZSOC 2011 to 2023 versions, there has been the introduction of new groups and subdivisions and an additional division, changes in the scope of existing categories, and expanded coding advice to support consistency.

Following publication of the updated classification, the courts administration agencies or statistical agencies in each state and territory have commenced implementation of the update into their systems. This has required changes to the coding relating to each offence type in their jurisdiction. While refinement of this coding continues, preliminary data on offences coded to ANZSOC 2023 have been provided in this release in Data cube 15 only.

The associated National Offence Index (NOI), which ranks each ANZSOC 2023 group according to perceived seriousness, was also updated in April 2024 to align. The new rankings have been incorporated into the derivation of the preliminary principal offence data. Where defendants had more than one offence in the same case, this may have contributed to changes in their derived principal offence.

As part of the migration to ANZSOC 2023, some states and territories identified improvements in previous coding to ANZSOC 2011, which may result in some unexpected changes in counts for this release.

Additional information will be supplied in the Criminal Courts, Australia methodology for 2024–25, including for each court level, when the principal offence output is fully transitioned to ANZSOC 2023.
