AIP weekly report · week ending 30 August 2026

Petrol prices in Sydney move through a pronounced cycle, so the day you fill up can matter as much as where. Prices tend to climb quickly to a peak, then drift down over the following stretch before the next rise, which means filling near the bottom of the cycle can make a real difference.

To see where the cycle sits right now, FuelCheck, a NSW Government service, publishes live prices from stations across the state. It's the quickest way to check what's actually on the board near you before you commit to a tank.
