Petrol price cycle

Petrol prices in metropolitan Perth and Mandurah currently follow a seven day cycle. 

Top up your tank on Tuesdays!

Tuesday is the cheapest day to fill up your tank in weekly petrol price cycle in metropolitan Perth and Mandurah. To keep track of the price cycle and find out which day into the cycle today is, visit FuelWatch price trends.

The cycle begins with a sharp increase one day (every Wednesday) followed by daily price decreases for six days.  On the last day of the seven day cycle, prices are generally at or below wholesale prices – this occurs every Tuesday and is generally the cheapest day of the cycle to purchase petrol.  As these low prices are unsustainable for retailers they then hike their petrol prices the next day, a Wednesday, and the cycle repeats. 

Regional WA generally does not have price cycles. 

What FuelWatch does

Western Australians can benefit from fuel price transparency and certainty because service stations must notify FuelWatch of their following day's prices by 2pm each day.  These prices are ‘locked in’ for 24 hours from 6am so motorists can make the best decision on where and when to buy their fuel.

Fuel prices in Australia

The Government (Commonwealth, State or Territory) does not set or control fuel prices in Australia.

Fuel prices go up and down for a number of reasons including changes to international benchmark prices; the value of the Australian dollar to the US dollar; local competition and the daily pricing decisions made by wholesalers and retailers. More detailed information about these factors can be found on the Australian Competition and Consumer Commission (ACCC) website.

At a Commonwealth level there is regulation in place to ensure the fuel sold is of an acceptable standard and to regulate the conduct of participants in the supply chain. 

Petrol price cycles in other areas

Petrol price cycles in the Eastern state capital cities vary in size and length.  Eastern states’ drivers are also impacted by fluctuations within the day, making it difficult to compare stations and get the cheapest fuel. 

For information on petrol price cycles in the Eastern states visit the ACCC’s website.
