6 Excluded from the collection are:
7 The count of periodic detainees covers the number of persons with an active periodic detainee warrant. However, periodic detainees who have breached orders may be excluded.
Types of facilities
8 The types of correctional facilities and programs where prisoners are held varies between the states and territories.
9 Included in the collection are:
10 Excluded from the collection are persons held in facilities administered and controlled by other agencies:
11 In all states and territories except Queensland, persons remanded or sentenced to adult custody are aged 18 years and over. Persons under 18 years are treated as juveniles in most Australian courts and are only remanded or sentenced to custody in adult prisons in exceptional circumstances. In Queensland 'adult' refers to persons aged 17 years and over.
12 Statistics in this publication are derived from information on each prisoner collected by the ABS from administrative records held by corrective services agencies within each state and territory.
JURISDICTION OF CUSTODY
13 Persons included in the National Prisoner Census were counted in the state or territory in which they were held in custody regardless of which state or territory imposed the sentence being served.
ABORIGINAL AND TORRES STRAIT ISLANDER IDENTIFICATION
14 The ABS conducts an ongoing program of quality assurance to monitor and improve the quality of Aboriginal and Torres Strait Islander status data in corrective services agencies. While the ABS has published Aboriginal and Torres Strait Islander status data in Prisoners in Australia for a number of years, quality assurance is required to better understand the level of accuracy over time.
15 The quality of the Aboriginal and Torres Strait Islander status information collected and recorded in corrective services agencies is assessed against the ABS Standard Indigenous Question (SIQ). The SIQ is based upon self-identification by the individual who comes into contact with corrective services agencies. The SIQ requires individuals to be asked “Are you of Aboriginal or Torres Strait Islander origin?”. The answers to the SIQ can be ‘No’, ‘Yes, Aboriginal’, or ‘Yes, Torres Strait Islander’. If the offender is of Aboriginal and Torres Strait Islander origin, both responses should be identified. If an offender does not supply an answer to this question, or is not asked, the Indigenous status field should be recorded as 'not stated'.
16 For custodial corrections, current indications are that corrective services agencies in all states and territories, except Western Australia, ask the SIQ as described above.
17 Some persons in custody are recorded with an unknown Aboriginal and Torres Strait Islander status on the information systems of corrective services agencies as their status has not been able to be obtained. Unknowns accounted for 1.0% of all records in 2010.
18 Imprisonment rates enable comparison of prisoner populations across states and territories at a point in time, as well as over time. Prisoner rates are expressed per 100,000 adult population, which is in accord with international and state and territory practices.
19 Rates for the adult prisoner population are calculated using the estimated resident population (ERP) for each of the states and territories, and total Australia (see Australian Demographic Statistics (cat. no. 3101.0)). All estimates and projections for the Australian Capital Territory exclude Jervis Bay Territory. All estimates and projections for Australia exclude the external territories of Christmas Island and the Cocos (Keeling) Islands.
20 The formula for calculating the imprisonment rate per 100,000 persons is: no. prisoners / Estimated Resident Population x 100,000.
21 The formula for calculating the ratio of two imprisonment rates is as follows: imprisonment rate 1 / imprisonment rate 2.
22 As the population changes over time the denominator used for the calculation of rates varies, depending on the reference period. The ERP series are revised every five years to incorporate additional information available from the latest Census of Population and Housing. The rates per 100,000 adult persons (excluding Indigenous rates) presented in this issue are based on the following ERPs:
23 For population estimates and information on the methodology used to produce the ERP, see Australian Demographic Statistics (cat. no. 3101.0). Data are sourced from the March 2010 release of this same issue.
24 The age at which a person is remanded or sentenced to adult custody within the states and territories can vary. See paragraph 11 for more information. In order to standardise the national imprisonment rate, the same denominator is applied for all states and territories. From 2009 the denominator used to derive this data item is based on the national ERP for persons aged 17 years and over. For individual state and territory imprisonment rates the denominator applied is based on the age at which a person is remanded/sentenced in that state. This may result in slightly different national imprisonment rates across Tables 2.3, 3.3 and 3.4.
National imprisonment rates
25 Prior to 2009 the denominator used to derive the national imprisonment rate is based on the national ERP for persons aged 18 years and over for all states and territories except Queensland. For Queensland this is based on persons aged 17 years and over.
State and territory imprisonment rates
26 From 2006 the ERP used in the calculation of state and territory imprisonment rates is that of persons aged 18 years and over, except for Queensland. For Queensland, the ERP used is that of persons aged 17 years and over. In 2004 and 2005 imprisonment rates were calculated using the ERP for all persons aged 18 years and over for all states and territories except Victoria and Queensland, where persons aged 17 years and over were included in the ERP for those states. Prior to 2004 imprisonment rates for all states and territories were calculated using the ERP for all persons aged 17 years and over. For more information refer to paragraphs 11 and 94.
27 Prior to 2009, imprisonment rate data for the Australian Capital Territory are calculated on the basis of the total number of Australian Capital Territory prisoners held in New South Wales prisons, as well as in the Australian Capital Territory. New South Wales imprisonment rates data are only based on the count of New South Wales prisoners held in New South Wales prisons. For more information about Australian Capital Territory prisoners held in New South Wales prisons refer to paragraph 104.
Country of birth imprisonment rates
28 Imprisonment rates by birthplace are calculated using data for June 2009 ERP by Country of Birth from Migration, Australia 2008-09 (cat. no. 3412.0).
Aboriginal and Torres Strait Islander imprisonment rates
29 Rates for the Aboriginal and Torres Strait Islander and non-Indigenous adult population have been revised in this issue due to the rebasing of estimates and projections for the Aboriginal and Torres Strait Islander population in September 2010. Rebased estimates (for the period 1986-2006) and projections (2007-2021) of the Aboriginal and Torres Strait Islander population are based on data from the 2006 Census of Population and Housing and use assumptions about future fertility, paternity, life expectancy at birth and migration.
30 The data supersede previously published ABS estimates and projections and, as a result, Aboriginal and Torres Strait Islander imprisonment rates previously published in Prisoners in Australia for the years 1999-2008 have been revised accordingly.
31 The projections used in this issue are based on Series B, which is one of two main projection series (Series A and B) that have been published for the years 2007 to 2021. Both of these series assume an annual decline of 0.5% in fertility rates; an annual increase of 1% in paternity rates; constant interstate migration at levels observed in the 2006 Census; and zero net overseas migration with no arrivals and no departures. Two different assumptions were made about future Aboriginal and Torres Strait Islander life expectancy at birth for Australia:
32 The impact of re-basing Aboriginal and Torres Strait Islander imprisonment rate data using Series B projections is small at the national level, with some differences more apparent in the state and territory data. The decision to use Series B as the denominator in the calculation of Aboriginal and Torres Strait Islander imprisonment rates for Prisoners in Australia followed consultation with the National Corrective Services Statistics Advisory Group and other stakeholders.
33 For further information see Experimental Estimates and Projections, Aboriginal and Torres Strait Islander Australians, 1991 to 2021 (cat. no. 3238.0).
Age standardisation of imprisonment rates
34 Age standardisation is a statistical method that adjusts crude rates to account for age differences between study populations.
35 There are differences in the age distributions between Australia's Aboriginal and Torres Strait Islander and non-Indigenous populations with the former having a much younger population. In 2001, the proportion of Aboriginal and Torres Strait Islander people aged 18 years and over was 54.6%, compared with 75.8% of non-Indigenous people (and 75.3% of the total Australian population). The diagram below illustrates the differences in age distributions.
36 ESTIMATED RESIDENT POPULATION, AUSTRALIA - 30 JUNE 2001
37 Due to these differing age profiles, using crude rates to examine differences between Aboriginal and Torres Strait Islander and non-Indigenous populations may lead to erroneous conclusions being drawn about variables that are correlated with age.
38 By making comparisons across age groups, we know that imprisonment rates decrease in older age groups, i.e. that the imprisonment rate is correlated with age. If we compare overall imprisonment rates between Aboriginal and Torres Strait Islander and non-Indigenous persons, it is likely that the imprisonment rate in the Aboriginal and Torres Strait Islander population will be higher because of the larger proportion of young people in the Aboriginal and Torres Strait Islander population.
39 Age standardised Aboriginal and Torres Strait Islander and non-Indigenous imprisonment rates have been presented in Tables 3.3 and 4.2 of this publication. Ratios of the rates are also included in these tables. The standard population against which each population is age standardised is the total Australian Estimated Resident Population at 30 June 2001. The standard population is revised every ten years; the next revision will be based on data from the 2011 Census.
Australian Standard Offence Classification
40 The offence categories used for national corrective services statistics in this publication are classified to the division level of the Australian Standard Offence Classification (ASOC) 2008 (Second edition) (cat. no. 1234.0). ASOC provides a national framework for classifying offences for statistical purposes, and was first released in 1997. In 2008 the ABS released the second edition of ASOC, which reflects changes that have occurred in criminal legislation since the first edition was released, as well as satisfying emerging user requirements for offence data.
41 For the 2009 Prisoner Census, all jurisdictions implemented ASOC08 for the provision of offence data with the exception of Queensland and Western Australia which were still supplying offence data on ASOC97. This process had some level of impact to the time series prior to 2009 and to comparability across jurisdictions. The classification changes affected the most serious offence for sentenced prisoners and the most serious charge for unsentenced prisoners. Issues of the publication prior to 2009 were based on the Australian Standard Offence Classification 1997 (cat. no. 1234.0). Prior to 2001, offence data were based on the Australian National Classification of Offences (ANCO) 1985 (cat. no. 1234.0).
42 In 2009, four jurisdictions (New South Wales, Victoria, Tasmania and the Northern Territory) supplied offence data coded to both ASOC97 and ASOC08, which enabled an assessment of the impact of the changes to the classification on the prisoner census data. As part of the implementation, jurisdictions also rectified a number of codes that were miscoded in previous years.
43 The analysis conducted found that the overall impact to the offence data, resulting from the new classification, was minimal. The most serious offence/charge for some prisoners moved between offence categories as a result of the classification change and the rectification of miscoding of some offences, however the total number of prisoners was not impacted. Four divisions (05, 11, 13 and 16) recorded changes of 15% or greater, however this was largely due to small numbers. All other divisions recorded changes below 15%. For more information refer to the Technical Note in Prisoners in Australia, 2009 (cat. no. 4517.0).
44 For the 2010 Prisoner Census, both Queensland and Western Australia implemented ASOC08, however dual coded extracts were not able to be supplied to measure the impacts to offence data. Based on the findings of the 2009 analysis, it is expected that the impact on Queensland and Western Australia's offence data resulting from the implementation of ASOC08 would be similar to those of other jurisdictions.
45 Some corrective services agencies have not fully implemented any version of ASOC. Data from these jurisdictions are coded to the defunct ANCO. ANCO data is then mapped by jurisdictions to the relevant ASOC category. Where there is no direct concordance between the two classifications, the ANCO codes have been mapped as closely as possible to the relevant ASOC categories.
National Offence Index
46 The National Offence Index (NOI) is a tool which provides an ordinal ranking of all ASOC groups in ASOC according to the perceived seriousness of each offence. The purpose of the NOI is to enable the representation of a prisoner by a single offence/charge in instances where multiple offences/charges occur for the same prisoner. The original NOI was introduced into the Prisoners collection in 2006, and was revised in 2009 to accommodate the changes made in ASOC08. For further information about the NOI refer to National Offence Index, 2009 (cat. no. 1234.0.55.001).
47 In the Prisoners collection the NOI is used to determine the most serious charge for unsentenced prisoners for all states and territories, except Western Australia. For sentenced prisoners, the concept of most serious offence is determined by the longest sentence in the current episode for a single count of an offence for all states and territories, except Tasmania due to the use of global sentencing in that state. For more information about global sentencing in Tasmania, see paragraph 82. Detailed information about the most serious charge and most serious offence can be found in paragraphs 81-84.
Standard Australian Classification of Countries
48 Country of birth information is classified according to the Standard Australian Classification of Countries (SACC), Second Edition (cat. no. 1269.0).
49 An episode is defined as the period from an offender's latest date of reception into the custody of a corrective services agency for a particular offence(s)/charge(s) until the person is released from custody. When a prisoner breaches parole conditions and is returned to custody, a new episode is deemed to have commenced and a new reception date is provided. Differences in the application of this rule occur in Western Australia. Further detail on these differences is provided in paragraph 71.
50 In consultation with the National Corrective Services Statistics Advisory Group, the definition of an episode changed from the 2003 Prisoner Census to maximise data comparability across states and territories. There was no change to the data provided by New South Wales, Victoria, South Australia and the Northern Territory as these jurisdictions had always provided data based on the definition of an episode as outlined in paragraph 49. These jurisdictions accounted for 65% of the prisoner population in 2002. Prior to 2003, Queensland, Tasmania and the Australian Capital Territory treated persons who breached parole and returned to custody as continuing a prior episode. These jurisdictions now provide data based on the standard definition of episode. In Western Australia, as noted in the previous paragraph, there remain differences in the application of the national counting rule. As the revised definition of episode only impacts on prisoners who have breached parole, the impact of this change in definition on time series data is low at the national level.
51 The legal status of an offender is determined by the warrant(s) or court order(s) which provide the legal basis for the detention in custody of the offender. Some offenders may have more than one type of warrant issued against them; therefore it is possible for an offender to have dual status (e.g. under sentence for some offences and awaiting appeal results for others, or under sentence and awaiting deportation). The counting rules for determining the legal status of an offender are as follows:
52 The aggregate sentence is the longest period that the convicted prisoner may be detained for the current sentenced offences in the current episode. Charges pending which are likely to extend the current episode are ignored. Where a new episode is counted when a person returns to prison from a breach of parole, the unexpired sentence of the prior episode is usually incorporated into the aggregate sentence for the new episode.
Expected time to serve
53 The expected time to serve is the period of imprisonment which a convicted prisoner is expected to serve and in most cases refers to the time between the date of reception for this episode (see paragraphs 49-50) and the earliest date of release for sentenced prisoners.
54 Date of reception is defined as the date the prisoner was received into prison in a state or territory for the current episode. Counting rules for persons returning to custody from an escape attempt or parole are as follows:
55 There are some state and territory variations:
56 The minimum term is the period that must be served before the prisoner is eligible for release from custody to parole, and the difference between the maximum and minimum term is the period that will be served on parole if the prisoner is released at his or her earliest eligibility date. While parole is generally granted at the earliest eligibility date, prisoners may be denied parole for some or all of the period up to the expiry of their maximum term. For both fixed and maximum-minimum sentences, the period actually served in custody may be less than the stated time to serve where administrative mechanisms such as sentence remissions are applied.
57 The time a prisoner is expected to serve in custody depends upon the sentence(s) originally handed down, the system of remissions and the forms of parole available in the various states and territories and whether any time was spent in custody prior to reception (for example, time on remand or in police custody). The rules governing date of release are complex and differ between the states and territories. The calculation of the earliest date of release in each state and territory is described in paragraphs 59-76.
58 Expected time to serve is not calculated for prisoners sentenced to an Indefinite term or to Life where no minimum term has been fixed.
New South Wales
59 In New South Wales significant legislative amendments came into force in April 2000, repealing a number of Acts of Parliament which were administered by the Department of Corrective Services, namely:
60 These Acts were replaced by the following:
61 The consolidation of the sentencing legislation into two Acts was achieved with only minor changes of substance to existing law. Under current legislation a court, in setting a term of imprisonment, is required to first set a 'Non-Parole' period and then a 'Sentence' period. Alternatively a court may decline to set a 'Non-Parole' period. These sentences are referred to as 'Sentence/Non-Parole' and 'Sentence/Parole declined' sentence types respectively.
62 Those prisoners with a sentence of three years or less, being a sentence that has a non-parole period, are automatically released from custody at the expiry of the non-parole term. Those with a non-parole term greater than three years may be released by the NSW Parole Board at any time after serving the non-parole term.
63 In Victoria, the calculation of expected time to serve is based on either the non-parole period set by court or the aggregate sentence. Time spent in detention prior to the commencement of the sentence counts toward the time expected to be served under sentence. Under the provisions of the Sentencing Act 1991 (as amended), the sentencing rules in Victoria are as follows:
64 In Queensland, with the exception of sentences of indefinite length such as Life, earliest release date calculations are based on the date an offender was eligible for parole.
65 Release dates are calculated as follows:
66 In South Australia, the Truth in Sentencing legislation implemented in August 1994 changed the way in which release dates are calculated in comparison to previous years. The major changes to the sentencing legislation affected by the Truth in Sentencing were: the abolition of remissions; the requirement for prisoners with an aggregate sentence of five years or more to formally apply to the Parole Board for release on parole; the ability of the Parole Board to release prisoners with an aggregate sentence of five years or more at its discretion; and directions for the judiciary to take the abolition of remissions into account when ordering sentences. Prisoners with a non-parole period (NPP) and an aggregate sentence of less than five years continue to be paroled automatically. Release dates for prisoners are now calculated as follows:
67 In Western Australia, expected time to serve is determined differently depending on whether sentences are less than 12 months or sentences are 12 months or more.
Sentences less than 12 months
68 For sentences less than 12 months, expected time to serve is determined as follows:
Sentences 12 months or more
69 For sentences 12 months or more expected time to serve is determined as follows:
70 If EED or RRED have passed, any release date set by the Prisoners Review Board is taken into account. If the Prisoners Review Board has not set a release date but has set a review date, that review date is used. If there are no such dates, the EDR (for sentences imposed before August 2003) or sentence expiry date (for sentences imposed on/after August 2003) is used.
71 Where prisoners were returned to prison partly or wholly as a result of breach or suspension of early release orders, a new episode is not deemed to have commenced and the date of reception is based on the date the person originally entered into custody, prior to being released on the early release order. Therefore, time spent in prison for the original sentence has continued to be included in the calculation of expected time to serve and aggregate sentence length data and may result in a higher mean and median duration for these data items in comparison with other states and territories (see paragraph 78). In light of legislative changes effective from August 2003, it is essential for Western Australia to have a continuous series of comparable information to enable the monitoring and evaluation of the impact of the legislation, therefore it cannot comply with the current ABS counting rule.
72 In Tasmania the calculation of expected time to serve is based on the totality of the sentence liable to be served minus one-third, but shall not operate so as to reduce the sentence below three months.
73 From October 2002, as a result of legislative change, the courts are required to set a term of imprisonment comprising a maximum term and a minimum term. Prior to the legislative change, the courts set a fixed term of imprisonment.
74 In the Northern Territory sentence remissions for new prisoners were abolished in July 1996. Expected time to serve is therefore calculated as follows:
75 Following the commencement of the Sentencing (Crime of Murder) and Parole Reform Act 2003 (NT) in February 2004, prisoners receiving or currently serving a mandatory life sentence for murder can now be considered for release on parole after serving 20 or 25 years. Prior to sentencing legislation amendments in 2004, prisoners sentenced for murder were given a mandatory life sentence without the possibility of receiving an earliest date of release, e.g. parole.
Australian Capital Territory
76 Prisoners sentenced in the Australian Capital Territory and who were held in New South Wales prisons were subject to New South Wales calculations for date of release. As at 30 June 2009, Australian Capital Territory prisoners were no longer held in New South Wales prisons.
Impact of indeterminate sentences
77 While all states and territories have access to indeterminate sentences as a sentencing option, the degree to which that sentencing option is utilised varies considerably across states and territories, particularly for homicide. This can impact on mean and median aggregate sentence length and expected time to serve data as prisoners with an indeterminate sentence are excluded from these calculations. For 2010, at least two-thirds of prisoners with a most serious offence of homicide had an indeterminate sentence in South Australia (75%), Western Australia (70%) and Queensland (66%). For the Australian Capital Territory, the proportion was closer to the national average of 32%. However, the proportions in the remaining states of New South Wales, Victoria, Tasmania and the Northern Territory were 10% or less.
Mean/median sentence length and time on remand
78 Calculations of mean and median sentence lengths and time on remand are affected by the reference period used. For the Prisoner Census, information relates to the characteristics of prisoners at a point in time (the night of 30 June), rather than the total prisoner population during the year. During a year, a large proportion of prisoners who go through the prison system serve short sentences (i.e. less than a year) or are on remand for shorter periods of time, while at any point in time the majority tend to be prisoners serving longer sentences or who have been on remand for long periods of time. The impact of this is that when the total population of prisoners during a year is considered, the large number of short sentences and short periods of time on remand will result in lower mean and median sentence length and time on remand values compared with means and medians calculated from point in time data.
79 Mean and median aggregate sentence length exclude indeterminate, life with a minimum and periodic detention sentences.
80 Between 1995 and 2001, prisoners who had a 'Life with minimum' sentence were not included as part of the calculation of the mean and median sentence lengths for prisoners' expected time to serve in prison. From 2002 they have been included. Their inclusion has slightly increased the mean for the expected time to serve, but has had a negligible impact on the median value for expected time to serve.
MOST SERIOUS OFFENCE/CHARGE
81 For sentenced prisoners in all states and territories except Tasmania, the Most Serious Offence (MSO) is the offence for which the prisoner has received the longest sentence in the current episode for a single count of the offence, regardless of the possible result of any appeals, and regardless of whether the sentence for that offence has actually expired at census date. Where sentences are equal, or the longest sentence cannot be determined, the MSO is the offence with the lowest (numerical) ASOC code. For example, if a prisoner has two offences coded at the ASOC Group level: 0711 Unlawful entry with intent, and 0412 Dangerous or negligent driving, the MSO would be allocated as 0412 Dangerous or negligent driving, as this is the lowest ASOC code.
82 In Tasmania, magistrates and judges have the capacity to provide global sentencing, i.e. a combined sentence for all offences. An individual offence will not have an identified period of imprisonment, so it is not possible to identify the offence with the longest period of imprisonment. The MSO is therefore determined by applying the NOI.
83 From 2004, the MSO for prisoners who have breached parole and returned to prison is determined only from the breach offence and any new offence(s) committed while on parole (the original MSO is excluded from the determination). This differs in Western Australia where offences from previous episodes are considered in the selection of MSO, due to the episode definition applied by Western Australia (see paragraph 71).
84 Prior to 2006, all states and territories applied the Most Serious Charge (MSC) for unsentenced prisoners by determining the charge which carries the longest statutory maximum penalty. From 2006, the NOI has been used by Victoria, Queensland, South Australia, Tasmania and the Australian Capital Territory. From 2007, the Northern Territory also applied the NOI, and in 2008, New South Wales introduced it. Western Australia continues to apply the charge which carries the longest statutory maximum penalty; where penalties are equal, the MSC is the charge with the lowest ANCO code. There are some state and territory variations:
COURT OF SENTENCE/REMAND
85 The court of sentence/remand data (available in Supplementary Data Cubes 4, 10 and 11) refer to whether the offender was sentenced or remanded to custody by the Supreme Court, the District or County Court or the Lower Courts such as the Magistrates' or Children's Courts. The rules adopted for coding the level of court are:
DATA COMPARABILITY AND SIGNIFICANT EVENTS
86 National corrections statistics are compiled in order to maximise comparability across states and territories. Although differences have been overcome through the introduction of national standards, some legislative, interpretive and processing differences remain.
New South Wales
87 In New South Wales, the Kariong juvenile facility operates under the authority of Adult Corrective Services. These prisoners are excluded from this collection.
88 Periodic detention is a form of custody or order where a sentenced prisoner is required to be held in custody on a part-time basis. This type of custody order is currently only used in New South Wales and the Australian Capital Territory. The periodic detention program has ceased in New South Wales from October 2010.
89 In September 2007, NSW opened the Wellington Correctional Centre. The focus of this facility is to accommodate maximum security prisoners from across NSW, as well as prisoners with lower security classifications from surrounding areas.
90 In September 2006, NSW opened the Compulsory Drug Treatment Correctional Centre (CDTCC). The CDTCC is an interagency endeavour - primarily between the Department of Corrective Services, Justice Health and the Attorney-General's Department. A multidisciplinary team at the Centre ensures treatment, rehabilitation and reintegration of male participants who have repeatedly offended in order to support a drug dependence.
91 Amendments to the Bail Amendment (Repeat Offenders) Act 2002 restrict the availability of bail for three classes of defendant:
92 The Judy Lazarus Transition Centre was opened in April 2007. The Centre provides a supervised pathway back into society for selected male prisoners nearing the end of their sentence.
93 In March 2006, Victoria opened Marngoneet Correctional Centre, Lara. The focus of this facility is to provide intensive treatment and offender management programs for males that have a minimum of six months of their sentence left to serve when they arrive there. The Metropolitan Remand Centre at Ravenhall was opened in April 2006. This facility provides increased capacity to hold prisoners awaiting trial or sentencing.
94 In July 2005, the Children and Young Persons (Age Jurisdiction) Act 2004 came into force in Victoria. This Act changed the definition of a child from a person under 17 years of age to a person under 18 years of age. As a consequence the definition of an adult also changed for corrective services data to a person aged 18 years and over. Data prior to 2006 includes persons aged 17 years.
95 For 2002 and previous years, when a prisoner was held on remand and then sentenced to a term of imprisonment as part of the one episode, the time on remand was considered a separate episode of imprisonment for the purposes of determining whether a prisoner had known prior adult imprisonment. This practice was inconsistent with the national counting rule for the Prisoner Census and resulted in an inflated number (and proportion) of Victoria's prisoner population with known prior adult imprisonment under sentence. From 2003 the national counting rule was adopted for recording known prior adult imprisonment in Victoria.
96 The Corrective Services Act 2006 (Qld) commenced in August 2006. One key provision in the new legislation relates to the management of offenders subject to Court-ordered Parole. This new order ensures that offenders serve all of their sentence under supervision, either in a correctional centre or under community supervision. This new order provides courts with the power to specify a parole release date for persons who are sentenced to a term of imprisonment of 3 years or less. Court-ordered Parole is not available to sex offenders or serious violent offenders.
97 In September 2005, Queensland implemented a new offender management system - the Integrated Offender Management System (IOMS). As a consequence prior imprisonment data were understated. The ABS imputed prior imprisonment data for 2006 and 2007 as an interim measure. During 2008 changes were implemented to the IOMS system and business processes to improve the quality of the prior imprisonment data. Comparisons to data prior to 2008 should be used with caution as the data may no longer be comparable.
98 From 2003, the Prisoner Census includes those prisoners who are held in community custody centres and work camps in Queensland.
99 The large increase in prisoners from 2008 to 2009 was due to fewer offenders being granted parole by the Prisoner Review Board, increased incarcerations by the courts and the impact of the Truth in Sentencing legislation. Implemented in September 2008, the Truth in Sentencing legislation refers to the Sentencing Act (WA) 1995, Transitional Provisions which removes the automatic 1/3 discount for each and every offence that appears in WA Statute books.
100 The Risdon Prison Complex in Tasmania was opened in August 2006. This complex includes the Mary Hutchinson Women's Prison which was opened in May 2006. A men's maximum/medium security facility was also built within the complex.
101 The growth in the prison population in Tasmania recorded for 2005 has primarily resulted from an increase in the number of remand receptions over the 2004-2005 period. There had been no specific policy change causing this increase in remand receptions.
102 From 2003, the most serious offence/charge data for Tasmania has been determined by the application of the NOI as the longest sentence can no longer be attributed to a single offence (see paragraph 82).
103 In 2005, Northern Territory implemented new quality assurance processes in the extraction of their prior imprisonment data. The result of these processes has been an improvement in the quality of prior adult imprisonment under sentence data.
Australian Capital Territory
104 Prior to 2009, persons sentenced to full-time custody by the Australian Capital Territory were usually held in New South Wales prisons. A new prison facility to house Australian Capital Territory persons sentenced to full-time custody, the Alexander Maconochie Centre, began taking prisoners on 30 March 2009. As at 30 June 2009, all Australian Capital Territory prisoners held in New South Wales prisons had been relocated to the new Alexander Maconochie Centre.
105 From 2003 the count of periodic detainees covers the number of persons with an active periodic detainee warrant excluding those with an outstanding PDC warrant. Detainees with an outstanding PDC warrant are those who breached a Periodic Detention Order and have been issued a warrant for a further court hearing, but failed to attend. In 2002, all periodic detainees with a current warrant were included in the census count (i.e. including those who were in breach of an order).
