Adelaide Diesel Climbs to 194 Cents While Most of Australia Sees Prices Falling

Looking at the latest data from across Australia, South Australia stands out for all the wrong reasons this week. While diesel prices are falling or holding steady across most states, Adelaide and surrounding areas have pushed upward, with the state average climbing 4.6 cents to reach 194.2 cents per litre.

That 2.4% increase is notable when you consider what other states are doing. Western Australia just recorded a substantial 25.2 cent drop overnight, bringing its average down to 180.4 cents. Victoria is sitting flat at 180.8 cents. New South Wales is at 182.0 cents. South Australia, meanwhile, is pushing closer to the two dollar mark.

The SA Price Squeeze

What makes the South Australian situation particularly worth noting is the tight price spread. The cheapest diesel in the state sits at 175.9 cents while the most expensive reaches 201.9 cents, creating a spread of just 26 cents. Compare that with Victoria, where the spread between cheapest and dearest is a staggering 130.9 cents, from 159.0 to 289.9 cents, or NSW at 112.0 cents.

A narrow spread might sound like good news, but the data indicates otherwise. It means there are fewer bargain options available to SA motorists. When every servo in the state is pricing within a relatively tight band, there is less opportunity to shop around and find a deal.

By contrast, Melbourne drivers in outer suburbs like Deer Park are finding diesel at 162.5 cents, a full 31.7 cents cheaper than the SA average. In Sydney, suburbs like Smithfield are averaging just 163.6 cents across three stations, while Granville stations have aligned at a uniform 164.5 cents.

Where the Cheapest Diesel Actually Is

A closer analysis reveals that the best diesel prices in Australia are consistently found in Western Australia and New South Wales this week. Byford in Perth's south is averaging 164.0 cents across three stations, with the cheapest at 159.5 cents. Fairfield in Sydney's west is at 164.9 cents, and Auburn sits at 167.6 cents.

The numbers tell an interesting story about geographic pricing patterns. While SA motorists are paying 194.2 cents on average, they could theoretically save over 30 cents per litre if they had access to the suburban pricing that Sydney and Perth drivers enjoy.

For those filling a 60 litre tank with diesel in Adelaide, that gap translates to roughly $18 more per fill compared to the best prices in Deer Park or Smithfield.

Queensland and the Northern Territory Remain Expensive

It is worth noting that South Australia is not the most expensive state for diesel. Queensland averages 206.8 cents per litre, though it did edge down 3.4 cents. The Northern Territory remains the standout at 235.4 cents, driven largely by remote stations where prices approach $4 per litre. Even Katherine, one of the Territory's more accessible regional towns, is averaging 173.5 cents.

Tasmania sits in the middle at 185.9 cents with a price spread of 86.1 cents across 239 stations, suggesting more variability and therefore more opportunity for savvy Tasmanian motorists to shop around.

What SA Motorists Should Know

The data indicates that South Australia's diesel pricing is being squeezed from both ends. Prices are higher than the eastern seaboard average and rising, while the tight spread limits the savings available through comparison shopping.

For Adelaide drivers, the key takeaway is that the cheapest servos in the state at 175.9 cents are still 16 to 18 cents above the cheapest options in Melbourne and Sydney. Motorists in Salisbury, Elizabeth, and Marion should keep a close eye on pricing as the state average approaches that psychological $2 per litre threshold.

The numbers are clear: with diesel climbing in SA while falling elsewhere, South Australian motorists are carrying a disproportionate share of the national fuel cost burden right now. Those who rely on diesel for work or commercial use would benefit from checking prices before filling up, as even a 10 cent difference at the bowser adds up to $6 on a standard tank.
