The reality is clear: petrol prices in NSW are rising. As of September 2025, the average price for regular unleaded petrol in Sydney sits at 184.8 cents per litre, with diesel at 183.0 cents per litre.
Australians feel the impact at every bowser, with households, businesses, and commuters adapting to these costs through smarter choices and new technology. Understanding why prices shift—and how to respond—can help NSW drivers save money and ease the financial strain.

Why Are Petrol Prices So High?
- Global crude oil benchmark prices, including Brent and Singapore MOGAS95, play a major role. These prices react to geopolitical factors such as Middle East conflicts and supply chain disruptions, which can send oil costs spiking overnight. OPEC+ oil production decisions, led by Saudi Arabia, Indonesia, and other nations, influence global supply and global oil markets.
- Exchange rates matter: Australia imports most refined fuel, so a weaker Australian dollar increases the cost of importing petrol and diesel; a direct pass-through to drivers.
- Federal taxes add up: The fuel excise rate on petrol and diesel is 49.2 cents per litre as of February 2025. This tax, plus the 10% goods and services tax (GST) added on top, makes government levies a significant chunk of the price you pay at the pump.
- Unique to Australia: Major cities like Sydney, Melbourne, Brisbane, Adelaide, and Perth experience petrol price cycles; unleaded petrol prices fall for several days, then jump suddenly due to retail competition tactics. Diesel does not follow this cycle and tends to be more stable.
- Global demand, local logistics, and even reserve bank commentary can all influence the broader economic climate that pushes fuel prices up or down.
The Economic and Social Ripple Effects
High fuel prices increase transport and logistics costs for businesses, which raises prices on groceries and other essentials, fueling broader inflation and piling pressure on household budgets.
Low-income families feel the burden most, increasing living pressures and, in some cases, causing economic fallout through reduced spending on essentials.
On the positive side, rising costs can shift behaviour—more people use public transport, carpool, cycle, walk, or work from home. These changes not only save money but also reduce environmental impacts. The broad knock-on effects of fuel price changes reach every part of city and suburban life.
Smart Strategies for NSW Drivers
1. Plan and Combine Trips
Minimise unnecessary driving. Use digital map tools to select the most efficient route, avoiding congestion and extra kilometres.
2. Drive Smarter
Accelerate gently, brake smoothly, and maintain a steady speed—cruise control on highways helps. Avoid engine idling and use air conditioning sparingly; open windows at low speeds instead.
3. Regular Vehicle Maintenance
A well-serviced engine runs more efficiently. Check and maintain tyre pressure; underinflated tyres increase fuel use. Use the fuel grade your car manufacturer recommends—avoid premium unless required.
4. Travel Light
Remove unnecessary weight from your vehicle. Take off roof racks and boxes when not in use.
5. Use Fuel Price Apps
Apps like FuelCheck NSW and PetrolSpy give you real-time price updates across your local area, helping you buy at the low point of the fuel cycle and save hundreds each year.
6. Join Loyalty Programs
Supermarket and service station loyalty programs often offer cents off per litre—small savings add up over time.
7. Explore Alternatives
Use public transport, carpool, cycle, walk, or work from home to cut fuel use. Even one or two days a week can make a big difference.
8. Think Long-Term
When it’s time for a new car, consider fuel-efficient vehicles, hybrids, or electric vehicles (EVs). EVs can cut fuel costs by up to 70% compared to petrol vehicles—especially if charged using solar or off-peak electricity.
9. Advocate and Stay Informed
Support policies that expand public transport, cycling infrastructure, and renewable energy. Collective action can reduce everyone’s living pressures from fuel costs.
AI Assistants: The New Ally in Fuel Savings
AI-powered navigation apps now optimise your route for fuel efficiency, avoiding traffic and unnecessary stops. Price comparison platforms analyse live data from thousands of petrol stations, alerting you to the best deals in real time.
Upcoming AI assistants may predict the optimal refill times based on price cycle trends and your own driving habits. For EV drivers, AI-managed charging can further cut costs by timing charging for the cheapest electricity rates. In short, modern AI tools are making it easier than ever to adapt to rising fuel prices.
