As we head into the cooler months of June 2026, thousands of Australians are packing up the ute or the family SUV for a mid-year road trip. But with the cost of living still front of mind, getting the best deal at the bowser is more crucial than ever.
If you are planning to hit the freeway this month, timing is everything. Following the supply chain disruptions in the Strait of Hormuz earlier this year, the Federal Government stepped in to temporarily halve the fuel excise by 26.3 cents per litre [8]. However, this relief measure is firmly scheduled to end on 30 June. Come 1 July, motorists will see a sharp spike at servos across the country. That makes June the perfect window to travel—if you know where to look for the best prices.
Global Shifts: What’s Driving the Market?
Beyond our shores, the global energy landscape is shifting dramatically. On 1 May 2026, the United Arab Emirates officially exited OPEC after nearly 60 years [3]. This historic departure allows the UAE to boost production outside of OPEC's strict quota system, which could introduce more supply into the market and eventually put downward pressure on prices. However, until those long-term benefits materialise, Australian fuel prices remain highly sensitive to geopolitical tensions and local refining costs.
State of the Servos: Current Fuel Prices Across Australia
Before you renew your rego and hit the road, it pays to analyse the current market. Right now, Unleaded 91 (U91) prices currently range from 155.3 cpl to 174.7 cpl nationally, a difference of 12.5%. The national average for U91 sits at 163.6 cpl.
Location plays a massive role in what you will pay. The top 3 cheapest capital cities for Unleaded 91 are currently Perth (165.77 cpl), Adelaide (168.21 cpl), and Sydney (172.61 cpl). In contrast, island and regional isolation drive prices up: Unleaded 91 prices are 9.7% higher in Hobart (181.86 cpl) than in Perth (165.77 cpl).
For those requiring premium fuels, the gaps are even wider. Premium 98 prices vary significantly across Australia, with Darwin (211.43 cpl) being 10.9% more expensive than Perth (190.68 cpl). In Sydney, Premium 95 (189.25 cpl) costs 9.6% more than Unleaded 91 (172.61 cpl).
Diesel drivers aren't immune to regional price shocks either. The national average for Diesel (DSL) is 187.7 cpl, but it is currently 10.4% more expensive in Canberra (224.75 cpl) compared to Newcastle (203.66 cpl).
Expert Tips for a Cost-Effective June Road Trip
1. Fill Up Before the Financial Year Ends
With the fuel excise cut ending on 30 June, make sure your tanks—and any approved jerry cans—are full before the clock strikes midnight on 1 July. The reinstatement of the excise will add an immediate 26.3 cents per litre to your fuel bill.
2. Leverage Real-Time Data
Gone are the days of driving from servo to servo to find the best price. To truly maximise your savings, use a dedicated platform like FuelRadar. Available on iOS and Android, FuelRadar helps drivers find the cheapest fuel nearby by providing real-time fuel prices Australia-wide. You can easily plan your fuel stops along your route by checking out our interactive map at FuelRadar Map.
3. Match Your Fuel to Your Budget
If your vehicle can handle alternative fuels, there are major savings to be had. For example, Brisbane motorists can save 1.5% by choosing E10 (173.49 cpl) over Unleaded 91 (176.15 cpl). The national average for E10 is 163.5 cpl, slightly edging out U91.
For dual-fuel vehicles, the benefits are undeniable. LPG (avg. 108.5 cpl) remains 33.7% cheaper than Unleaded 91 (avg. 163.6 cpl), offering significant savings for vehicles with dual-fuel capability.
If you're driving an electric vehicle, the cost benefits are staggering. Nationally, B20 (avg. 296.9 cpl) is 559.8% more expensive than EV (avg. 45 cpl). Other specialty fuels reflect varying costs, with E85 averaging 231.9 cpl and Premium Diesel (PDSL) sitting at 201.5 cpl.
4. Prep Your Vehicle
A well-maintained car is a fuel-efficient car. Before a long trip, check your tyre pressure; under-inflated tyres increase rolling resistance and burn more petrol. Remove empty roof racks to improve aerodynamics, and practice smooth driving behaviours on the freeway to stretch every litre further.
The Bottom Line
June 2026 presents a unique, time-sensitive opportunity for Australian motorists. By understanding the global market shifts, taking advantage of the final weeks of the fuel excise relief, and making smart choices at the bowser, you can keep your travel costs under control.
