FX.co ★ Australia’s Weighted Mean CPI Holds Steady at 3.6% YoY in August 2026

Australia’s weighted mean Consumer Price Index (CPI) rose 3.6% year-over-year in August 2026, unchanged from the 3.6% annual increase recorded in the second quarter of 2026. The latest data, updated on 30 September 2026, indicate that underlying inflationary pressures, as captured by the weighted mean measure, have stabilized rather than accelerating or easing further.

On a year-over-year basis, the August reading compares the price changes in August 2026 with the same month a year earlier, while the previous figure reflected the comparison between the second quarter of 2026 and the corresponding quarter in the prior year. The steady 3.6% rate suggests that Australia’s core inflation dynamics remain consistent over recent periods, providing policymakers and markets with a clearer view of the current price environment.
