Australia’s weighted mean Consumer Price Index (CPI) rose to 3.6% year-over-year in January 2026, up from 3.2% in December 2025, according to data updated on 25 February 2026. The figure, measured on a year-over-year basis, reflects the change in prices in January 2026 compared with January 2025.
The weighted mean CPI is a key core inflation gauge, as it filters out the most volatile price movements to provide a clearer view of underlying price pressures. The latest increase suggests that core inflation momentum strengthened at the start of 2026, reversing the softer pace recorded in December.
