Inflation in Australia
Consumer prices in Australia have risen 3,808.6% since Q3 1948, the start of the official series. That means A$100 then buys what A$3,908.57 buys in Q2 2026, so the same basket of goods now costs 39.1 times what it did. Over the most recent year on record, Q2 2025 to Q2 2026, prices rose 4.0%.

How inflation in Australia is measured
The figures above come from the Australian Bureau of Statistics (CPI, all groups, quarterly). The series is indexed so that a chosen base year equals 100, and the calculator works out the ratio between any two dates you pick.
Coverage runs from Q3 1948 to Q2 2026, and updates automatically as each new release is published. Australia publishes CPI once a quarter rather than monthly, so dates here are given as quarters. Figures for the most recent periods can be revised by the statistics office after first publication.
