How to read the outlook
The chart shows an estimated direction for the next 30 days. Use it as timing guidance, then check current reports at nearby stations.
If the outlook points to a meaningful jump in the next week, consider filling sooner if you need fuel.
If you can wait, recheck before filling a full tank. Small movements can still matter when you combine timing with a cheaper station.
Petrol cycle timing is only used for Sydney, Melbourne, Brisbane, Adelaide and Perth, and only when repeated price data supports it. Diesel, LPG and other cities use trend guidance with wider uncertainty.
Methodology
A short method note showing what feeds the forecast, the timeframes it is calibrated for and where it stops being useful.
90 days of daily city-average prices per fuel type, terminal gate prices from the Australian Institute of Petroleum, AUD/USD exchange rates, Brent crude oil prices, and the detected position within the current local price cycle.
The forecast checks the city's recent price cycle, then smooths the last 90 days of prices to estimate the next likely move. It shows a guide price and likely range, with later dates treated as less certain.
Outlooks refresh overnight. Same-day price moves are not reflected until the next refresh, so use the map for reported station prices and update times.
The outlook is most useful over the next week in the five capital-city cycle markets: Sydney, Melbourne, Brisbane, Adelaide and Perth. Diesel, LPG and cities outside those five use a steadier trend model instead of invented peak and trough dates.
Grounded market research now flags refinery outages, crude-oil moves, exchange-rate pressure and other recent events beside the forecast. Those reports explain uncertainty but cannot override the cents calculation; the model re-anchors only when verified price and wholesale data move.
Reporting rules and feed timing differ by state. NSW, Queensland and Victoria use government-backed reporting, while WA publishes fixed daily prices. Timing signals inherit source delays, so check the station update time before driving.

Common questions
Sydney, Melbourne, Brisbane, Adelaide and Perth are the five recognised petrol-cycle markets and usually have the clearest short-term signals. Diesel, LPG and other cities use trend guidance with wider uncertainty. The cents figure is a guide, not a promise.
