Price Cycles
Fuel Price Forecasts Explained (Australia)
How to use fuel price forecasts in Australia: cycle position, recent station moves, wholesale context, confidence and when to fill up.
Key points
Key takeaways
A fuel forecast is guidance, not a guaranteed price promise.
FuelRadar reads the cycle position beside 90 days of city prices, wholesale context, Brent crude and AUD/USD signals.
A forecast should change how much you buy: fill more near a low, buy less near a spike when you can wait.
Always confirm the station price and update time before driving for a forecasted saving.
Using this guide
Before you act on the guide
Check the station price, report time and distance before changing your route.
What a fuel price forecast can tell you
A fuel price forecast helps answer one question: should you fill up now, wait, or buy only enough to get through the next few days? It is not a guarantee of tomorrow's price at one station. Check the forecast against the latest station list for your fuel grade.
The five forecast inputs
FuelRadar combines the local retail cycle with broader cost signals, then turns that evidence into a fill-up signal. The inputs are strongest when they point in the same direction and weaker when the market is mixed.
| Input | What it tells you | How to read it |
|---|---|---|
| 90 days of city average prices | The recent normal range for that city and fuel type. | Shows whether today is high, low or ordinary for the local market. |
| Local price-cycle position | Where the city sits between the last reset and the next likely low. | Use it only where a current retail petrol cycle is evident. |
| Terminal gate prices | A wholesale benchmark before retail costs and margin. | Helps separate a retail price move from a broader cost trend. |
| Brent crude oil | Direction in a widely followed global crude-oil benchmark. | Use as background rather than a direct pump-price formula. |
| AUD/USD | The exchange-rate cost of fuel traded in US dollars. | A weaker Australian dollar can add cost pressure. |
How the signals become a recommendation
The forecast classifies the available evidence; it does not produce one certain station price. Confidence should be lower when recent updates are sparse, the inputs disagree or the current market is not following its historical cycle.
| Signal | What it means | Driver action |
|---|---|---|
| Fill now | The available data suggests limited benefit in waiting. | Compare current nearby station reports before a larger fill. |
| Wait if you can | Prices may have room to ease. | Buy only what you need if it is safe and practical to wait. |
| Compare nearby | Station prices are spread out or the timing signal is mixed. | Use the station list rather than the forecast alone. |
| Low confidence | Updates are sparse or the signals disagree. | Treat the forecast as background and make the station check first. |
What the forecast does not claim
FuelRadar does not claim to predict the exact price at every station tomorrow. Retailers can change prices at different times, and one suburb can move before another. A forecast is useful only when its scope, update time and confidence are clear.
Why forecasts differ by city
The ACCC reported materially different average cycle lengths across Sydney, Melbourne, Brisbane, Adelaide and Perth in 2025. Perth also has government-published next-day prices. Use a city-specific view and current station reports rather than a national weekday rule.
How to use the forecast
Open the city or price-cycle page, note the data time and confidence, then compare station prices for the exact fuel grade near where you drive. Include distance and update time before deciding how much to buy.

Frequently asked questions
No. They are directional guidance based on cycle position, recent station prices and market context. Always confirm the station price and update time before paying.
