New petrol data unveils cheapest cities ahead of long weekend


A new analysis from unveils petrol price trends in five major cities, flagging differences of nearly 5cpl and indicating what consumers may expect to pay at the bowser this Labour Day weekend.

Unleaded petrol (ULP) prices were measured across a 31-day period[1] in Adelaide, Perth, Sydney, Melbourne and Brisbane. Results revealed that Brisbane and Perth residents have taken the biggest hit at the bowser during this period with ULP prices averaging at 144.3cpl and 144.2cpl respectively. This was followed by Adelaide (140.6) and Sydney (140.5). It’s Melburnians, however, who got the most for their buck at the bowser, averaging at 139.5cpl – 4.8c cheaper than Brisbane.

While Queensland’s city may be the most expensive, the Brisbane petrol price cycle has been trending downward since the last peak on September 13, while Perth currently sits at the bottom of its price cycle. It’s also good news for Melbourne and Sydney residents, as their cycle appears to be on a downward trend. Adelaide is the only city where petrol prices have been inclining since September 28.

Abigail Koch, spokesperson at, says, “Australians looking to save while topping up the tank this holiday weekend need to be keeping an eye on these price cycles to ensure they’re refuelling when prices are at their lowest. Petrol stations in most cities follow a cycle of 10-22 days, offering low prices for two-to-three consecutive days within those cycles. The key to filling up on a cheaper day is to keep an eye on petrol prices in your area and identify the trend.”

Within the 31-day period prices peaked in Brisbane at 156.2cpl followed by Perth (150cpl), Sydney (149.2cpl), Melbourne (148.9cpl), and Adelaide (144.7cpl). has also unveiled the sub-regions in each city with the lowest 31 day average. While not the most expensive city for petrol, Sydney is the location with the highest difference in price per subregion – a difference of 6.5c between its cheapest (Hurstville 138.5cpl) and most expensive (Eastern Suburbs 145cpl). Brisbane had the second biggest price gap (4.7c) with its far south (142.6cpl) the cheapest and its west (147.3cpl) the most expensive.

Melburnians hoping to keep costs low would benefit from topping up in Frankston and Cranbourne (137.7cpl) if passing through those suburbs. Adelaide and Perth’s cheapest subregions were Payneham (139.2) and Girrawheen (142.3).
