What it measures
The quarterly CPI is the average of the three monthly index values in the quarter. The calendar shows the change compared with the same quarter a year earlier.
Who publishes it and when
Since the ABS moved to a complete monthly CPI in November 2025, the quarterly figure is published together with the monthly release for the last month of each quarter, at 11:30 Sydney time.
How it is put together
Because it is built from the monthly figures, it holds no new price information beyond them. The ABS keeps publishing it for indexation and for users who need quarterly series.
What traders watch
Most of the market attention is on the monthly figure released at the same time. The quarterly rate is mainly a check on the trend.
How markets have usually reacted
Since it is released with the monthly CPI, it rarely moves the market on its own.
Common mistakes
Reading the quarterly and monthly rates as two separate surprises; they come from the same data.
How a higher or lower figure is usually read
Higher quarterly inflation is usually read as supportive for the Australian dollar; lower inflation as negative. Not a signal.
