The Global Squeeze Hits the Aussie Bowser
For Australian motorists, May 2026 has delivered a perfect storm of global volatility and domestic policy shifts. International oil supplies have tightened dramatically due to the effective closure of the Strait of Hormuz, with Brent crude prices hovering around $106 per barrel. Adding to the market's unpredictability is the UAE's formal departure from OPEC on May 1, a historic move that has reshaped global production dynamics and prompted OPEC to cut its 2026 global oil demand growth forecast.
Here at home, the Federal Government has responded to these geopolitical shocks by announcing a massive $14.8 billion Australian Fuel Security and Resilience Package, which will establish the nation's first permanent government-owned fuel stockpile of diesel and aviation fuel. Meanwhile, the temporary fuel excise cut is scheduled to end on 30 June, and recent budget announcements confirm it will not be extended. Although national inflation has eased slightly to 4.3% in May, fuel pressures remain a sticky issue for household budgets.
National Fuel Price Breakdown
If you feel like you're paying more at the servos, the data backs you up. However, prices vary wildly depending on what you drive and where you fill up. Across our tracked stations, U91 prices currently range from 149.9 cpl to 174.9 cpl nationally, a difference of 16.7%. The national average for Unleaded 91 sits at 166.3 cpl, while standard Diesel (DSL) averages 214.1 cpl, and E10 averages 167.6 cpl.
For those with alternative or dual-fuel vehicles, the savings are clear. LPG (avg. 107.3 cpl) remains 35.5% cheaper than Unleaded 91, offering significant savings for vehicles with dual-fuel capability. At the extremes of the market, B20 biodiesel (avg. 309.9 cpl) is a staggering 588.7% more expensive than EV charging (avg. 45 cpl).
Capital City Clash: Where Are the Cheapest Servos?
When we analyse the capital city data, the geographic divide becomes stark. Adelaide currently offers the cheapest prices for 2 different fuel types, making it Australia's most affordable capital city for motorists. The top 3 cheapest capital cities for Unleaded 91 are currently Gold Coast (174.08 cpl), Adelaide (174.94 cpl), and Geelong (175.89 cpl).
Conversely, the Top End is feeling the pinch. Unleaded 91 prices are 9.9% higher in Darwin (191.30 cpl) than in Gold Coast (174.08 cpl). Premium 98 prices vary significantly across Australia, with Darwin (222.62 cpl) being 12% more expensive than Gold Coast (198.77 cpl).
Diesel drivers aren't immune to regional price shocks either. Diesel is currently 17% more expensive in Canberra (260.59 cpl) compared to Perth (222.67 cpl).
Expert Strategies to Maximise Your Mileage
With the excise cut ending soon and global markets in flux, changing your refuelling behaviour is the best way to protect your wallet. Here are our top tips:
- Optimise Your Fuel Choice: Don't pay for premium if your car doesn't need it. In Sydney, Premium 95 (196.88 cpl) costs 9% more than Unleaded 91 (180.61 cpl). Check your owner's manual—if it only requires U91, stick to it. Meanwhile, Brisbane motorists can save 1.1% by choosing E10 (178.88 cpl) over Unleaded 91 (180.89 cpl).
- Vehicle Maintenance: Keeping your car in top shape improves fuel efficiency. Check your tyre pressure regularly, ensure your rego is up to date, and avoid carrying unnecessary weight in the back of the ute or boot.
- Drive Smoothly: Aggressive acceleration on the freeway burns through petrol rapidly. Maintain a steady speed and anticipate traffic flow to minimise braking and accelerating.
