CPI inflation, change from a year earlier, Australia

CPI inflation, change from a year earlier, is the percent change in Australia's all groups consumer price index compared with the same quarter one year before. EconoMonitor calculates it from the quarterly index the Australian Bureau of Statistics publishes about four weeks after each quarter ends.

This is the rate the RBA's target refers to: the Bank aims to keep inflation between 2% and 3%, and focuses on the 2.5% midpoint. Comparing a quarter with the same quarter a year earlier cancels the seasonal pattern of the quarterly index, so it is the standard way to report Australian inflation and the basis for comparison with other countries on this site.

Keep three things in mind. Australian inflation is measured quarterly here, so the latest reading can be a quarter older than the monthly figures from the United States, Canada and the United Kingdom. Government measures such as electricity rebates or changes to childcare subsidies can lower or raise the headline for a year at a time without changing underlying pressure. And the RBA gives weight to the trimmed mean measure of underlying inflation, which can differ from this headline rate by a full percentage point.

CPI inflation, change from a year earlier is at its lowest since Q4 2025, when it stood at 3.63%. Within ten years, CPI inflation, change from a year earlier beats 78% of readings.
