What it measures

The change in the consumer price index over the past 12 months. The ABS has published a full monthly CPI since late 2025, so this monthly series is short; the quarterly measure has the long history.

Why it matters

The Reserve Bank aims to keep inflation between 2 and 3 per cent. Readings above that band are what keep rates high.
