The annual rate for September was 10.1 percentage points above the annual rate for August. That gap describes how much the year-on-year rate itself moved. It is not the amount prices changed within the month.

Comparing with the month before
Each figure compares one month with the same month a year earlier. So the September rate reflects price movements across the full year to September 2026, and the August rate the year to August 2026. The step from 13.5% to 23.6% means the year-on-year increase widened sharply between the two releases.

What it means for people in Australia
For anyone who buys petrol or diesel, the same purchase cost 23.6% more in September 2026 than it did a year before. That applies on average across the motor fuel measure.

The figures do not show how the rise was spread across states, cities or regional areas, or between petrol and diesel. They also do not show how much any particular household spends on fuel.

What the data does not tell us
The facts give two monthly annual rates and the gap between them. They do not include the pump price itself, the change within September alone, or a longer history.

The data does not explain why the annual rate rose. A large jump can come from prices rising this year, from prices having been low a year earlier, or both. These figures cannot separate the two.

Other price measures, such as overall consumer prices or electricity, are separate statistics with their own coverage. This report does not set them against the fuel figure.

AI analyst view
Little change expected low confidence next two releases
Estimate range: 20–24%
Why
- An annual rate holds onto any price rise for a full 12 months. A move from 13.5% to 23.6% points to a large lift in prices around September, and that lift stays in the comparison unless prices fall back. F1 F2 F3
- Fuel is one of the most volatile items in the price basket. Pump prices can reverse within weeks, so some easing from the September peak is plausible, which is why the range sits mostly below 23.6%. F1
- Without data on fuel prices a year earlier, base effects cannot be measured. That uncertainty is the main reason for low confidence. F1 F2
What would change this view
- If the October annual rate falls back to 13.5% or lower, the view would shift to down.
- If the October annual rate rises above 23.6%, the view would shift to up.
This is the AI’s own interpretation of the official figures above, not an official forecast. It may turn out wrong.
Scenarios to watch
- Scenario, not a forecast If pump prices hold near their September level, the annual rate would likely stay high in the next release, because the higher prices remain in the 12-month comparison.
- Scenario, not a forecast If fuel prices fall back in October, the annual rate could ease towards the August level, since the year-on-year gap would narrow.
- Scenario, not a forecast If prices keep climbing, or if fuel was unusually cheap in the same months last year, the annual rate could rise further.
What to check next
- The October 2026 motor fuel figure: does the 12-month rate stay above 13.5%?
- Whether the next release shows the September rise holding or reversing.
- The next consumer price release, read as a separate measure from the fuel figure.
