Australia's Summer Road Trip: Discover Cheapest Petrol Spots, January 2026

Hit the Road Smarter This Summer: Your Guide to Cheaper Fuel in January 2026

As the mercury rises and the school holidays beckon, countless Australian motorists are planning their great summer escape. Whether it’s a coastal cruise, a regional adventure, or a cross-country trek, a significant part of any road trip budget is fuel. With petrol prices constantly fluctuating, knowing where and when to fill up can make a substantial difference to your travel costs. As senior automotive journalists and fuel industry experts at FuelRadar, we’re here to equip you with the latest insights and actionable advice for a more affordable journey this January.

Understanding the Dynamics of Australian Fuel Prices

Australian fuel prices are influenced by a complex interplay of global and local factors. International crude oil prices, refining margins, the Australian dollar's exchange rate, and local competition all contribute to what you pay at the bowser. Geopolitical events, such as conflicts in oil-producing regions or decisions by OPEC, can have a ripple effect on prices that reaches our shores. Similarly, the strength of the Australian dollar against the US dollar is crucial, as crude oil is traded in US dollars; a weaker Aussie dollar means higher import costs that are passed on to consumers.

Supply and demand also play a significant role. Increased global demand, particularly during seasonal peaks like the northern hemisphere summer, can push prices upward, while slower global economic activity can lead to decreases. Refining margins, the cost of processing crude oil into petrol, are another factor, impacted by refinery operations and regulations.

In January 2026, global oil prices have seen some volatility. Crude oil plunged more than 5% earlier this month due to geopolitical developments, easing fears of supply disruptions. Despite this, analysts have previously warned of potential surges, with prices tipped to reach as high as $2.20 per litre due to rising global oil prices and escalating Middle East tensions. This underscores the importance of staying informed and using tools like FuelRadar to track real-time changes.

Capital City Fuel Price Overview: January 2026

Understanding the average fuel prices in our major capital cities is crucial for both daily commutes and longer journeys. Below is a comprehensive look at the average prices for various fuel types across Australia's capital cities as of January 2026.

Key Fuel Price Trends and Insights

Analysing the data reveals several important trends for Australian motorists this January:

• Unleaded 91 Disparity: Unleaded 91 prices are notably higher in Melbourne (195.57 cpl) compared to Adelaide (162.54 cpl), representing a significant 20.3% difference. This highlights how regional competition and supply chains can impact prices.
• Premium 98 Variance: Premium 98 prices show substantial variation across the nation, with Melbourne (220.37 cpl) being 18.8% more expensive than Perth (185.55 cpl). Drivers of vehicles requiring premium fuels should be particularly vigilant.
• Diesel Costs: Diesel is currently 12.5% more expensive in Canberra (196.11 cpl) when compared to Adelaide (174.36 cpl). This is a vital consideration for ute and truck drivers.
• Sydney Fuel Choices: In Sydney, Premium 95 (190.73 cpl) costs 11.4% more than Unleaded 91 (171.28 cpl). Understanding your vehicle's specific fuel requirements and the real-world benefits of premium fuels versus their cost is key.
• E10 Savings in Brisbane: Brisbane motorists can save 1.8% by opting for E10 (188.22 cpl) over Unleaded 91 (191.69 cpl). E10, a blend of unleaded petrol and up to 10% ethanol, is often a more economical and environmentally friendlier choice for compatible vehicles.
• LPG vs. Premium 98: Nationally, Premium 98 (averaging 174.1 cpl) is 61.8% more expensive than LPG (averaging 107.6 cpl). For those with LPG-compatible vehicles, this represents substantial potential savings.

Expert Tips for Fuel Efficiency and Savings on Your Summer Road Trip

Beyond finding the cheapest petrol, there are numerous ways to reduce your fuel consumption and make your summer travels more economical. The Australian government is also pushing for greater fuel efficiency with the New Vehicle Efficiency Standard (NVES) introduced in July 2025, which aims to bring more efficient cars to Australia, ultimately saving motorists money at the pump.

1. Smart Driving Habits

• Smooth Acceleration and Braking: Aggressive driving uses significantly more fuel. Accelerate gently and anticipate traffic to avoid sudden braking.
• Maintain a Consistent Speed: Using cruise control on freeways helps maintain a steady speed, which is more fuel-efficient than constant speed adjustments.
• Avoid Excessive Idling: If you're going to be stopped for more than 60 seconds, it's generally more fuel-efficient to switch off your engine and restart when ready.
• Adhere to Speed Limits: Driving at higher speeds dramatically increases aerodynamic drag, leading to greater fuel consumption.

2. Vehicle Maintenance is Key

• Check Tyre Pressure Regularly: Under-inflated tyres increase rolling resistance, forcing your engine to work harder and consume more fuel. Check your tyre pressures at least once a month.
• Regular Servicing: A well-maintained engine runs more efficiently. Ensure your vehicle's air filters, spark plugs, and oil are clean and in good condition as per your manufacturer's schedule.
• Lighten Your Load: Remove any unnecessary weight from your boot or roof racks. Extra weight means your engine uses more energy to move the vehicle.
• Optimise Air Conditioning Usage: While essential in an Australian summer, excessive air conditioning use can increase fuel consumption. Use it judiciously.

3. Fuel Choice and Planning

• Choose the Right Fuel: For many vehicles, regular Unleaded 91 or E10 (if compatible) is sufficient. Only use premium fuels (P95 or P98) if your vehicle manufacturer specifically recommends or requires it. Paying for higher octane when your car doesn't need it is simply throwing money away.
• Plan Your Route: Use navigation apps to find the most direct routes and avoid heavy traffic, which leads to stop-start driving and increased fuel use.
• Fill Up Strategically: Don't wait until your tank is nearly empty. Plan your refuelling stops in areas known for lower prices, or when you are in a cheaper part of the fuel cycle.
