Annual change in the all groups Consumer Price Index for Australia, from the ABS monthly CPI.
All groups CPI, annual change
4.0%
Data for: August 2026
Previous: 3.5% (July 2026)
What it is
The CPI measures household inflation across a basket of goods and services such as food, housing, transport and health. The ABS now publishes a complete monthly CPI.
Why it matters
The Reserve Bank of Australia sets the cash rate to keep inflation between 2% and 3%, so CPI releases move expectations for interest rates and mortgage repayments. Many pensions and payments are indexed to the CPI.

Reading the australia inflation rate (cpi) figure
What the latest australia inflation rate (cpi) reading says
The most recent value on this page is 4.0%, for August 2026. Against the previous reading of 3.5%, that is +0.5% — a move up. Monthly, near the end of the following month is how often Australian Bureau of Statistics, Consumer Price Index, Australia (monthly) publishes it, so a single reading is a snapshot and not a trend. The 17 observations in the table above, from April 2025 onwards, are what gives the figure context.
Where the australia inflation rate (cpi) figure sits in its own history
Across the 17 readings loaded here, the series moved between 1.9% and 4.6%. The latest value sits inside that range, so nothing in this window is exceptional. A window this short cannot show a cycle. It shows the direction of travel and the size of the usual swing, which is enough to tell a normal move from an unusual one, and no more than that.
Who sets the australia inflation rate (cpi) and who it affects in Australia
Australian Bureau of Statistics, Consumer Price Index, Australia (monthly) publishes the australia inflation rate (cpi) series, and the page links the exact dataset and its licence below. Nothing here is a second-hand copy: the figure above is read from that source and shown with the date the source gave it. People reach this page searching for "inflation rate australia", and the honest answer is the published figure plus its date. A national figure is an average: your own rate, bill or salary in Australia will sit above or below it.
Glossary
Policy rate
The interest rate a central bank sets to steer the economy, and the floor under most other rates in that currency. It moves only when the rate-setting committee decides, so its history is a series of steps rather than a continuous line.
Year-on-year inflation
The change in a price index against the same month a year earlier. It can fall while prices are still rising, because it measures the speed of the increase, not the level of prices.
Basis point
One hundredth of a percentage point. Central banks and markets talk in basis points because "a 0.25 point cut" and "a 25 basis point cut" are the same thing, and the second wording leaves no room for doubt.
Real rate
An interest rate after inflation is taken out, roughly the quoted rate minus the inflation rate. A savings account paying less than inflation has a negative real rate, which means the money loses purchasing power.
Revision
A later correction of a published figure, as the statistics office receives more complete data. Values marked provisional or estimated are the ones most likely to change, which is why the page keeps the source flag.
National average
A figure averaged over a whole country, and therefore not a quote for you. Your own mortgage rate, salary or grocery bill depends on your region, your lender or your shop and will sit above or below the average.
Yield
The annual return an investor earns by lending money through a bond, expressed as a percentage of its price. Price and yield move in opposite directions: when a bond gets cheaper, its yield rises.
Update frequency: Monthly, near the end of the following month
