What the Perth petrol price cycle means

A price cycle is a rise and fall in retail unleaded petrol prices. Prices commonly rise over a short period and then fall more gradually. The cycle comes from retailer pricing decisions rather than a matching rise and fall in wholesale costs.

Perth's recent pattern

Perth and Mandurah currently have a seven-day unleaded petrol cycle. FuelWatch also publishes tomorrow's notified prices after 2:30pm. Historical averages are useful background, not a timetable. Check the current cycle chart and reported station prices before deciding how much to buy.

When prices are near the lower end

If reported prices are near the lower end of the cycle, compare nearby stations and their update times before a larger fill. A city average can hide a sizeable difference between service stations.

After prices rise

After a sharp rise, compare stations because retailers do not all move at once. If you can safely wait, a smaller fill may be enough while prices ease. Do not rely on a fixed weekday: for Perth, compare today with tomorrow after FuelWatch publishes the next day's prices at 2:30pm.

Check the source

FuelRadar shows the local cycle and reported station prices. The ACCC petrol price-cycle page publishes current buying tips for the five largest cities. Always check the fuel grade and report time before travelling further for a lower price.

Common questions

How does the Perth fuel price cycle work?

Prices usually jump during a reset and then ease over time. The important question is whether the market is near the high or the low end of the cycle.

Is the Perth cycle more important than suburb choice?

They work together. When the city is near a reset, timing usually matters more. When the market is calmer, suburb choice can deliver the biggest saving.

How do I track the Perth cycle properly?

Use the FuelRadar city page, price-cycle page and forecast together. You can see recent station prices, compare nearby areas and check whether prices are rising or falling.
