Tasmania Records Australia's Cheapest Diesel at 169 Cents While the State Average Climbs Past $2
A detailed analysis of this week's diesel pricing data has uncovered a striking contradiction in Tasmania. While the state's average diesel price climbed 5.4 cents overnight to 207.8 cents per litre, a cluster of servos in the northeast corner of the island is selling diesel for as little as 169.9 cents, making Scottsdale home to some of the cheapest diesel anywhere in the country.
The numbers tell a remarkable story. Across five stations in Scottsdale, the price spread has blown out to 46 cents per litre. That means two servos in the same small town, population just over 2,000, are charging prices that differ by almost 50 cents. For a driver filling a 70 litre tank, that is a difference of $32.20 depending on which side of town they pull in.
Breaking down the regional differences, the cheapest diesel in Scottsdale sits at 169.9 cents while the most expensive station in the same area is asking 215.9 cents. The town's average of 197.6 cents still undercuts the Tasmanian state average of 207.8 cents, but that 46 cent gap within a single postcode is one of the widest in the country for a town of that size.
How Tasmania Compares Nationally
According to recent data, Tasmania's diesel situation sits in the middle of a broader national picture that varies enormously by state. Victoria currently records the lowest state average at 203.4 cents, though that figure masks an extraordinary spread of 220 cents between its cheapest and most expensive outlets. At the other end, the Northern Territory continues to hold the unwanted title of most expensive state for diesel, averaging 244.8 cents with a spread of 251.7 cents.
Western Australia has also seen notable movement, with diesel climbing 6.8 cents to 205.0 cents. Regional WA towns tell their own story. In Albany, diesel prices jumped 21.1 cents overnight to an average of 208.0 cents, with similar increases recorded across premium fuels. Geraldton, further north, is faring better at 196.1 cents average across seven stations, while Dongara sits at a similar level.
But the single biggest overnight movement belongs to New South Wales, where the state diesel average surged 20.1 cents, a 10.49 per cent increase, to reach 211.8 cents. Regional NSW towns like Barham on the Victorian border remain competitive at 173.7 cents for the cheapest outlet, but the state average has pulled well ahead of most other jurisdictions.
The Spread Story
Historical data suggests that price spreads within individual towns tend to widen during periods of wholesale price volatility, and this week's figures are consistent with that pattern. The national data reveals just how much motorists can save by shopping around within their own suburb.
In Victoria, the pattern is equally pronounced. Reservoir has a diesel spread of 37 cents across seven stations, from 175.9 cents to 212.9 cents. Nearby Footscray shows a 27 cent gap, and Moonee Ponds has a 20 cent difference across five outlets. These are not small towns separated by vast distances. These are inner and middle suburbs of Melbourne where competing servos sit within a few minutes drive of each other.
The tightest spreads tend to appear in smaller regional centres. Wee Waa in northwest NSW has just a 3.1 cent gap across three stations, while Doveton in Melbourne's southeast records a 4 cent spread. The data paints a clear picture: competition in larger suburbs does not always translate to lower prices, but it does create opportunities for drivers who are willing to compare before they fill.
What This Means for Motorists
The overnight diesel increases across multiple states point to wholesale cost pressures flowing through to the bowser. Industry factors including international benchmark pricing and shipping costs continue to influence what Australians pay, but the degree to which those costs are passed on varies dramatically between outlets.
For Tasmanian motorists in particular, the Scottsdale example demonstrates that geography alone does not determine price. A town of 2,000 people has both some of the cheapest diesel in the nation and outlets charging well above the state average. The same pattern repeats in Katherine in the Territory, where diesel ranges from 185.9 to 199.9 cents, and in Wanneroo north of Perth, where the spread reaches 25.4 cents.
For motorists willing to shop around, the data clearly demonstrates that location and timing remain the two most important factors in fuel savings. With diesel spreads of 46 cents in Scottsdale, 37 cents in Reservoir, and 32 cents in Oberon, there are genuine savings available for those who check prices before pulling in to fill up.
