A new ACCC petrol industry report has revealed that independent petrol retail chains Speedway, Metro Petroleum, United, Vibe and FuelXpress had the cheapest petrol in Australia’s eight capital cities in 2020.

The report shows the average range between the highest and lowest-priced major petrol retailers across Sydney, Melbourne, Brisbane, Perth and Adelaide, increased to 11.4 cents per litre (cpl) in 2020, from 8.4 cpl in 2019.

The ACCC’s analysis shows that motorists in Australia’s five largest cities could have saved a combined total of nearly half a billion dollars ($485 million) in 2020 by switching from a variety of higher-priced to lower-priced major retailers.

“The range of petrol prices available to most Australian motorists means the potential savings from filling up at one of the cheaper retailers are very significant,” ACCC Chair Rod Sims said.

“Consumers should bear in mind that regular unleaded petrol sold in Australia typically comes from the same refineries or import terminals, and there are minimum quality standards that all retailers are required to adhere to. This means that motorists are getting petrol of a similar quality regardless of where they fill up,” Sims said.

The report compares different major retailers’ annual average petrol prices in 2020 with the market average price and reveals the savings that an average motorist could have made by switching from the highest to lowest-priced major retailer in each of Australia’s capital cities.

Large retailers that refine and sell wholesale petrol, as well as selling it at the retail level, were the most expensive major retailers in most capital cities. These were Coles Express (where Viva Energy sets prices) in Brisbane and Canberra, BP (for those service stations that are company owned and operated) in Sydney and Melbourne, and Caltex (for those service stations that are company owned and operated) in Adelaide.

In the other capital cities, the most expensive retailers were BP Sanzone (a BP branded independent chain) in Perth, Puma Energy in Darwin, and small independents in Hobart.

In 2020, a motorist in Sydney could have saved around $445 for the year by choosing to fill up at the lowest-priced independent chain rather than the highest-priced major retailer. Similar savings would have been around $317 in Melbourne, $174 in Brisbane, $330 in Adelaide, $216 in Perth, $200 in Canberra, $78 in Hobart and $55 in Darwin.

“While price is undoubtedly the biggest influence on consumers’ decision about where to buy petrol, it’s important to acknowledge that factors such as location, type of fuel sold, the ability to use discount vouchers, and convenience store offerings all play a part as well,” Sims said.

“Our analysis shows that in the four years from 2017 to 2020, certain independent chains were consistently the lowest-priced major petrol retailers across the capital cities.

“There are a number of independent chains in our largest capital cities with many retail sites, so a lot of motorists won’t have to go far to find cheaper fuel if they want it.”

The report shows that in Sydney there were six independent chains with average prices below the market average price, representing about one in four of more than 800 retail sites. In the other capital cities, independent chains represented around two in five retail sites in Brisbane, one in three in Darwin, one in four in Perth, one in five in Melbourne, Canberra and Hobart, and one in six in Adelaide.

Over the past seven years, the ACCC has championed greater fuel price transparency for consumers in Australia through its court action and policy advocacy.
