Measures of Consumer Price Inflation

The consumer price index (CPI) is a quarterly measure of inflation published by the Australian Bureau of Statistics (ABS). The ABS also publishes a monthly CPI indicator, which is more timely and includes updated prices for around two-thirds of the CPI basket each month.
