Fuel prices in Sydney 2026, including the cheapest service stations, the petrol price cycle, and how to track price drops to save money
Cost of Living Desk is a contributing writer covering cost-of-living and public affairs for The Sydney Times.
Fuel prices in Sydney follow a cyclical pattern known as the petrol price cycle. The cycle is driven by the pricing strategies of the major retailers, including Coles Express, Woolworths Plus, and 7-Eleven. The cycle typically lasts between four and six weeks, with prices rising to a peak and then falling to a trough. The peak-to-trough difference is typically 40 to 60 cents per litre for unleaded petrol.
The NSW Government monitors fuel prices through the FuelCheck program. FuelCheck publishes real-time fuel prices for more than 500 service stations across NSW. The prices are updated every five minutes and are available through the FuelCheck website and mobile app.
The petrol price cycle in Sydney has three phases: a rising phase, a peak phase, and a falling phase. The rising phase typically lasts one to two weeks, during which prices increase by 10 to 20 cents per litre. The peak phase typically lasts one week, during which prices remain at the highest point of the cycle. The falling phase typically lasts one to two weeks, during which prices decrease by 30 to 40 cents per litre.
The cycle is driven by the major retailers, who coordinate their price increases to maximise their margins. The cycle is not random, and it is possible to predict when prices will rise and fall. The cheapest time to buy fuel is at the bottom of the cycle, which typically occurs two to three weeks after the peak.
The cheapest service stations in Sydney are usually located in the outer suburbs and are not associated with a major supermarket. The cheapest service stations in Sydney as of mid-2026 include:
United Petroleum has several locations across Sydney, including in the western suburbs and the southern suburbs. United Petroleum consistently has some of the cheapest fuel prices in Sydney.
7-Eleven has several locations across Sydney. 7-Eleven prices are generally cheaper than Coles Express and Woolworths Plus, but more expensive than independent retailers.
Independent service stations are often the cheapest option in Sydney. Independent service stations are not associated with a major supermarket and do not offer discount fuel dockets. However, their base prices are often lower than the major retailers.
The NRMA publishes a list of the cheapest fuel stations in Sydney on its Fuel Check website. The website allows you to search by location and fuel type and shows the cheapest stations in your area.
The best way to save money on fuel is to track price drops and fill up when prices are at their lowest. There are several tools available to help you track price drops:
FuelCheck App. The NSW Government FuelCheck app publishes real-time fuel prices for more than 500 service stations across NSW. The app allows you to set price alerts for your preferred fuel type and location. The app sends you a notification when a station in your area drops below your target price.
NRMA Fuel Check App. The NRMA Fuel Check app is a free app that publishes real-time fuel prices and provides price predictions based on the petrol price cycle. The app allows you to set price alerts and shows you the cheapest stations in your area.
GasBuddy. GasBuddy is a community-based fuel price app that allows users to report fuel prices at service stations across Australia. The app shows you the cheapest stations in your area and provides price predictions based on the petrol price cycle.
Coles and Woolworths offer fuel discounts to customers who spend a minimum amount at their supermarkets. The discounts are offered through the Coles Express and Woolworths Plus programs. The discount is typically 4 cents per litre when you spend $20 or more at the supermarket, and 8 cents per litre when you spend $40 or more. The discount is applied at the pump when you present your loyalty card or app.
The fuel discounts can provide significant savings if you are already shopping at Coles or Woolworths. However, the discounts can also encourage you to fill up more often than you need to, which can negate the savings. The best strategy is to combine the fuel discount with a low base price at the service station.
Diesel prices in Sydney follow a different cycle to unleaded petrol. Diesel prices are influenced by global crude oil prices and the exchange rate. Diesel prices are typically higher than unleaded petrol prices, but the difference varies depending on global oil prices. Diesel prices are published on the FuelCheck website and app.
LPG prices in Sydney are lower than petrol prices, but LPG is not available at all service stations. The NRMA publishes a list of service stations that sell LPG on its website.
Electric vehicle charging prices in Sydney vary depending on the charging network and the location. The major charging networks in Sydney are Chargefox, Evie Networks, and Tesla Supercharger. The cost of charging an electric vehicle at a public charging station is typically 30 to 50 cents per kilowatt-hour, which is equivalent to 10 to 15 cents per kilometre. Many electric vehicle owners charge their vehicles at home overnight, when electricity prices are lower.
