Electricity

Electricity rose 33.9% in the 12 months to September. The annual rise in electricity costs is primarily related to State Government rebates being used up by households combined with annual price reviews in July that increased electricity prices across all capital cities.

In September last year, State Government electricity rebates that were in place included the Queensland $1,000 State rebate, the Western Australia $400 State rebate and the Tasmania $250 State rebate. Over the year, those rebates have been used up and those programs have finished. As a result, households in those States have higher out of pocket electricity costs in September 2025 than they did in September 2024.

For households in Western Australia, the 2024-25 Commonwealth Energy Bill Relief Fund (EBRF) rebate was also in place in September last year. This year, Western Australian households will receive the payment from the extended Commonwealth EBRF rebate program from 11 October. This change in the timing of EBRF payments for Western Australian households also contributed to higher out of pocket electricity costs in September 2025 than in September 2024.

About the monthly CPI indicator

What is the monthly CPI Indicator?

The monthly Consumer Price Index (CPI) indicator was developed to provide inflation data at a higher frequency for use by governments, economists and the wider community. The quarterly CPI remains the principal measure of household inflation.

Monthly CPI Indicator coverage

The monthly CPI indicator is derived using available data from the quarterly CPI. The ABS collects prices for the CPI in a range of frequencies including monthly, quarterly, and annual. The frequency of price collection is determined by how often prices change. Where price change occurs frequently, such as for food and petrol, monthly price data is collected. Where price change is less frequent, such as for restaurant meals and hairdressers, price data is available quarterly. In some cases, prices are collected once per year where it is known prices only change annually. This is the case for some education fees, property rates and private health insurance.

For this reason, the composition of the monthly CPI basket varies across the three months of the quarter, details of the monthly coverage composition are detailed in Table 1 below.

Introducing monthly indicators of underlying inflation

The December 2022 release of the monthly CPI indicator stated

"The release of the monthly CPI indicator includes a Trimmed mean series which was intended to provide additional analytical insights into inflation on a monthly basis. The ABS has identified that the Trimmed mean series is not, however, providing a reliable indicator for the principal measure of trimmed mean inflation published in the quarterly CPI publication. The ABS will suspend the publication of the monthly Trimmed mean series while we investigate."

Since this decision the ABS has investigated the monthly trimmed mean measure and assessed alternative measures of underlying inflation.

Investigation of monthly Trimmed mean

The investigation found there was a downward bias in the monthly Trimmed mean when compared to the quarterly Trimmed mean, which is considered the principal measure of underlying inflation. The bias was evident during a period of rising inflation caused by the use of carry forward imputation for some monthly data. Details on the carry forward imputation approach are provided in Introducing a monthly CPI indicator. Carry forward imputation is not used in the quarterly CPI and therefore does not affect the quarterly Trimmed mean.

Alternative measures of underlying inflation

The ABS assessed variations of established measures of underlying inflation. Two alternatives were found to be a reasonable indicator of annual movements of the quarterly Trimmed mean:

Annual trimmed mean. This measure uses a similar method to the quarterly trimmed mean. The key difference is rather than use the quarterly movements in the trimming process, the annual movements are used. In this case, each month the annual movements of the 87 CPI series are ranked from lowest to highest. The top and bottom 15% of annual movements are removed, with the average is taken from the middle 70% of annual movements. For more details on the Trimmed mean method see Underlying Inflation Measures: Explaining the Trimmed Mean.
CPI excluding volatile items and holiday travel. CPI exclusion based measures are used by many countries to provide different insights into CPI inflation by removing the effects of certain items. Typically, the price change for these items tend to be volatile and often not reflective of the underlying inflationary trends. This new measure builds on the existing 'CPI excluding volatile items' series and also excludes holiday travel. Volatile items are fruit, vegetables and automotive fuel.

For holiday travel, it has been shown that events such as Christmas and Easter, as well as school holidays, have a significant impact on airfare and accommodation prices. This sees monthly movements for holiday travel as quite volatile. By calculating a series that excludes the monthly movements of holiday travel and the other volatile items, the monthly movements at the aggregate CPI level provide a reasonable insight of underlying inflation.

Measuring Rents in the CPI

New data source

As outlined in the ABS’ information paper Introducing a monthly CPI indicator for Australia, from July 2022 the ABS has incorporated a new data source to measure the Rents series in the monthly CPI indicator and the quarterly CPI.
The Rents series prior to July 2022 was measured on a quarterly basis using a survey of approximately 4,000 rental properties collected directly from real estate agents.
The new dataset obtained by the ABS is updated monthly and includes approximately 480,000 rental properties that are used to produce the CPI Rents series across all capital cities.

What the CPI Rents series measures

The CPI measures the prices being paid by households for the goods and services that they consume during a particular measurement period (e.g. month or quarter). In the case of rents, this means that the CPI measures the current ‘price’ being paid by all types of households that rent including new and existing renters who are renting privately or from the government.
Measures of rental inflation that are based on newly advertised rental properties only measure changes in the asking or advertised price of rental properties for new tenancies. At any given time, newly advertised tenancies represent a relatively small proportion of properties being rented in Australia. The Rents series used for the CPI measures actual rents paid rather than advertised prices.
Advertised rents tend to reflect the dynamic end of the rental market where the price change for new tenancies can be more volatile than that being experienced by renters with existing tenancy agreements.
Price changes observed in advertised rents series are expected to eventually flow through to the CPI Rents series. However, the small share of rental properties leased to new tenants each quarter means that it takes some time for changes in advertised rents to impact price change observed in the CPI Rents series.
A useful analogy is to think about a bathtub of water. The water in the tub represents all rents being paid by households, while the water entering the tub from the tap represents new rental agreements. The CPI series is measuring the overall temperature of the bathtub whereas an advertised rents series measures the temperature of the water flowing into the tub. It will take some time for the flow of water to change the overall temperature of the water in the bathtub.

Using price indexes

Price indexes published by the Australian Bureau of Statistics (ABS) provide summary measures of the movements in various categories of prices over time. They are published primarily for use in Government economic analysis.

Consistent with existing policy, the ABS does not comment on the use (or otherwise) of the price indexes we publish. However, it should be noted that the monthly CPI indicator may be routinely subject to revision, in contrast to the quarterly CPI which is only revised in exceptional circumstances.

Use of Price Indexes in Contracts sets out a range of issues that should be taken into account by parties considering including an Indexation Clause in a contract using an ABS published price index.

Frequently asked questions

Frequently Asked Questions (FAQs) specific to the monthly CPI indicator can be found in the Information paper: Introducing a monthly CPI indicator for Australia FAQs

In addition, the Frequently Asked Questions page has answers to a number of common questions to do with price indexes and the quarterly Consumer Price Index in particular.

Methodology

Scope

The monthly CPI indicator is a general measure of price change for goods and services purchased by Australian households.

Geography

Monthly data is published at the national level, derived as a weighted average of the eight capital cities.

Source

Prices are collected for a range of goods and services (the CPI basket) from a variety of retailers across the eight capital cities.

Collection method

Prices are collected in a range of frequencies including monthly, quarterly, and annually using:

web-scraping
online and telephone collections from retailers
administrative data, including supermarket scanner data.

Concepts, sources and methods

Information about the data sources and methods used to compile the CPI is contained in the Consumer Price Index: Concepts, Sources and Methods.
