Queensland Diesel Stays Above 209 Cents as Three States Cluster Below 183

Looking at the latest diesel pricing data from 26th February 2026, one number immediately stands out: 209.4 cents a litre. That is Queensland's current average, making it the most expensive mainland state for diesel by a substantial margin.

The data tells an interesting story about a widening north south divide in Australian fuel markets.

Three States Converge Below 183 Cents

A closer analysis of today's figures reveals a notable convergence among three states. Victoria is averaging 180.8 cents, Western Australia sits at 181.3 cents, and New South Wales has come in at 182.2 cents. All three are now within 1.4 cents of each other.

That clustering is particularly striking given recent movements. NSW diesel has dropped a remarkable 47.8 cents from its previous average of 230 cents, a 20.8 percent decline. WA has also fallen 24.6 cents. The result is three major states converging on a price band that sits roughly 27 cents below Queensland.

For a motorist filling a standard 60 litre tank, the difference between Queensland and these three states amounts to roughly $16 per fill up.

The Full State Rankings

The complete state by state picture reveals significant variation across the country:

Worth noting is the position of Tasmania at 186 cents. While the island state's average is competitive, its spread of 84.1 cents from cheapest to most expensive station tells its own story. Some Tasmanian servos are pricing diesel at 159.9 cents while others charge 244 cents, a gap that illustrates the premium regional communities continue to pay.

Inside Queensland's 60 Cent Spread

Queensland's 80 reporting stations show prices ranging from 170.5 cents to 230.9 cents, a spread of 60.4 cents. That floor price of 170.5 cents indicates that sharp eyed Brisbane motorists can still find diesel below the national mainland average if they know where to look.

The challenge is that most Queensland stations are pricing well above the 200 cent mark. Competition in Brisbane's suburbs and the Gold Coast corridor typically offers some relief, while regional centres such as Toowoomba, Cairns, and Townsville tend to sit at the higher end of that range.

Data indicates that Queensland's premium over southern states has been a consistent pattern through February 2026, suggesting structural factors rather than temporary market fluctuations.

The Cheapest Suburbs Nationally

Across the country, the most competitive diesel is concentrated in Sydney's western suburbs and Melbourne's northern corridors. Smithfield in western Sydney is averaging 163.6 cents across three stations, while Granville has all three of its stations aligned at 164.5 cents. Fairfield is also competitive at 164.9 cents.

In Melbourne, Deer Park averages 168.5 cents and Thomastown sits at 172.6 cents across eight stations, offering consistent competition.

In Perth, suburbs like Byford at 165.4 cents and Kwinana Beach at 167.5 cents remain among the most affordable options nationally.

Actionable Takeaways

The analysis reveals a few clear points for Australian motorists.

For Queensland drivers, the 60 cent internal spread means comparison shopping genuinely matters. The difference between filling up at the cheapest and most expensive servo in the state amounts to $36 on a 60 litre tank. Checking prices on our interactive fuel map before heading to the bowser is well worth the effort.

For drivers in Victoria, NSW, and WA, the current convergence below 183 cents represents genuinely competitive pricing. This may reflect the tail end of a pricing cycle, making now a reasonable time to fill up before the next upswing.

The numbers are clear: motorists who check prices before filling up can save substantially, regardless of which state they call home. With spreads ranging from 22 cents in South Australia to 84 cents in Tasmania, the difference between the cheapest and most expensive servo in your area could add up to hundreds of dollars over a year of driving.
