Key statistics

  • The Consumer Price Index (CPI) rose 0.2% this quarter.
  • Over the twelve months to the December 2024 quarter, the CPI rose 2.4%.
  • The most significant price rises this quarter were Recreation and culture (+1.5%) and Alcohol and tobacco (+2.4%).

What's new this quarter

Correction to Child care costs in the CPI

As explained in the ABS media statement released on 19 November 2024, Correction to child care costs in the CPI, out-of-pocket child care costs have been corrected as part of compiling the December 2024 quarter. The ABS made errors in estimating the impact of the Government’s reforms to the Child Care Subsidy when they took effect in July 2023.

The correction applied this quarter reduced the Child care index by 5.8 per cent and reduced the Preschool and primary education index by 0.4 per cent. This meant the CPI quarterly movement was 0.05 percentage points lower than it would otherwise have been without the correction, and the Trimmed mean quarterly movement was 0.03 percentage points lower than it would otherwise have been.

Energy Bill Relief Fund rebates

The 2024-25 Commonwealth Energy Bill Relief Fund rebates and State government rebates applied from July 2024. These rebates have had the effect of reducing electricity costs for households in the September and December 2024 quarters. More details on the impact and timing of these rebates are provided below. 

Trimmed mean table added

A table has been included in this release which shows the CPI Expenditure Classes that were trimmed out to calculate the Trimmed mean in the December 2024 quarter. Details are available in Trimmed mean measure.

Update to the CPI weights next quarter

The CPI weights are updated each year to ensure the weights used in the CPI basket reflect contemporary household spending patterns. The weights will next be updated in the March 2025 quarter. The updated CPI weights will be published at the same time as the January Monthly CPI indicator release on 26 February 2025.

Monthly CPI Indicator

The latest monthly inflation data can be found in the Monthly CPI Indicator. For more information on how the Monthly CPI Indicator relates to the quarterly CPI see Introducing a monthly CPI indicator for Australia

Overview

CPI and Trimmed mean annual inflation both lower

Annual CPI inflation was 2.4 per cent in the December quarter, down from 2.8 per cent in the September quarter. The main reasons for lower CPI inflation were due to a fall in prices for electricity and automotive fuel and moderating price rises for new dwellings.

The Trimmed mean provides a view of underlying inflation by reducing the effect of irregular or temporary price changes that can impact the CPI. This quarter the Trimmed mean excluded the falls in both electricity and automotive fuel, alongside other large price rises and falls. Trimmed mean annual inflation was 3.2 per cent, down from 3.6 per cent in the September quarter.

Goods inflation lowest since 2016

Annual Goods inflation was 0.8 per cent, down from 1.4 per cent in the previous quarter. The drop in annual Goods inflation was primarily due to large falls in electricity and automotive fuel prices and lower price rises for new dwellings.

Services inflation remains elevated

Annual Services inflation was 4.3 per cent in the December quarter, down from 4.6 per cent in the September quarter. Higher prices for rents, medical and hospital services and insurance were the main contributors to Services inflation remaining elevated.

Non-discretionary inflation lowest since 2021

Non-discretionary goods and services include those that households are less able to reduce their consumption of, like food, automotive fuel, housing and health costs, whereas Discretionary goods and services reflect more optional purchases.

In the December 2024 quarter Non-discretionary annual inflation fell to 1.8 per cent while Discretionary annual inflation rose to 3.2 per cent. The drop in Non-discretionary inflation was from lower prices for automotive fuel and electricity over the past 12 months, as well as lower inflation for food and non-alcoholic beverages, and new dwellings. This contributed to the lowest Non-discretionary annual inflation since the March 2021 quarter. 

Energy Bill Relief Fund rebates reduce electricity bills

Electricity prices fell 9.9 per cent in the December quarter and 25.2 per cent in the past 12 months. 

The introduction of the 2024-25 Commonwealth Energy Bill Relief Fund (EBRF) rebates from July 2024 were the main driver for the fall in electricity prices this quarter. 

Households in all States and Territories received their second instalment of the Commonwealth EBRF rebate this quarter. Households in some States and Territories did not receive their first instalment of the Commonwealth EBRF rebate in the September quarter due to differences in the roll out schedule. The fall this quarter was driven by these households receiving two $75 instalments of the Commonwealth rebate in the December quarter. 

Excluding the rebates, electricity prices would have risen by 0.2 per cent in the December 2024 quarter. 

The following graph shows the impact the rebates have had on the Electricity series in the CPI since the September 2023 quarter.

(c) For States and Territories receiving rebates from August, the households whose billing cycle is in July 2024 have received two instalments in October 2024.

(d) In New South Wales and Victoria, the first instalment of Energy Bill Relief Fund 2024-25 has been paid from part way through August 2024. The remaining proportion of households whose billing cycle is in August have received their first instalment in November 2024.

Automotive fuel prices lower compared to 12 months ago

Automotive fuel prices fell 7.9 per cent over the 12 months to the December quarter, reflecting lower global oil prices over the year. 

New dwelling price growth lowest since 2021

New dwelling prices rose 2.9 per cent over the 12 months to the December quarter, down from 4.8 per cent in the September quarter. This is the weakest annual rise since the June 2021 quarter. 

The lower annual price growth in new dwellings reflects project home builders increasing incentives and promotional offers to entice new business in a subdued new home market.

Rental price growth moderated by Commonwealth Rent Assistance changes

Rental prices rose 6.4 per cent over the 12 months to the December quarter, down from 6.7 per cent in the September quarter. Rental price growth continues to reflect low vacancy rates and a tight rental market. 


Changes to Commonwealth Rent Assistance

The rate of annual growth in rental prices has been moderated by changes to Commonwealth Rent Assistance (CRA). 

The maximum rate available for CRA increased by 10 per cent on 20 September 2024, in addition to the usual biannual CPI indexation on 20 March and 20 September each year. This follows an additional increase to CRA maximum rates of 15 per cent in September last year. These increases to CRA have reduced the amount of rent payable by eligible recipients.

The September quarter results showed a partial impact of the CRA changes, while the remaining impact has been reflected in the December 2024 quarter. 

Excluding the changes to CRA, rents would have increased by 7.8 per cent over the 12 months to the December 2024 quarter.

(a) Commonwealth Rent Assistance (CRA) maximum rates increased by 15% on top of the usual biannual CPI indexation from 20 September 2023. 
(b) Commonwealth Rent Assistance (CRA) maximum rates increased by 10% on top of the usual biannual CPI indexation from 20 September 2024. 

Annual food inflation eases slightly

Food prices rose 3.0 per cent over the 12 months to the December quarter, down from 3.3 per cent in the September quarter. Price rises eased across most food categories apart for Meat and seafoods which included lamb price increases of 17.3 per cent over the year.

Fruit and vegetable prices remained 6.3 per cent higher compared to 12 months ago, despite falling 3.3 per cent this quarter. Supply continues to improve with prices falling in recent months for tomatoes, cucumbers, beans, mangoes and strawberries due to favourable growing conditions.

Trimmed mean measure

The following table summarises the Expenditure Classes that were excluded ('trimmed out') as part of the calculation of the quarterly Trimmed Mean.

There are three steps involved in calculating the Trimmed Mean. Firstly, the seasonally adjusted quarterly percentage changes for each of the 87 CPI Expenditure Classes (ECs) are calculated and ranked from lowest to highest. Each EC has a weight that represents the proportion of expenditure spent on it out of total household expenditure. The second step uses these weights to work out which ECs (including parts of the ECs that are on the 15 per cent and 85 per cent borders) make up the top and bottom 15 per cent of the distribution. These are the ECs that are 'trimmed out'. Finally the Trimmed Mean is calculated as the weighted average of the quarterly movements for the remaining 70 per cent of ECs by weight.

Two important points to note about how the Trimmed mean is calculated are:

  1. The selection and number of ECs trimmed changes from quarter to quarter depending on the distribution of the quarterly movements and the weights of the ECs at the lower and upper end of the distribution.
  2. To produce the Trimmed mean, the seasonally adjusted quarterly movement for each EC is used. Without the use of seasonally adjusted movements, some ECs may always be excluded from the Trimmed mean due to the volatile nature of their price change resulting from seasonal factors (e.g. holiday travel).

Using price indexes

Price indexes in contracts

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. Price indexes are also often used in contracts by businesses and government to adjust payments and/or charges to take account of changes in categories of prices (Indexation Clauses).

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.
