Motorists in Coober Pedy are being left scratching their heads—and digging deeper into their pockets—after fuel prices in town have failed to move, despite clear downward pressure from both government relief and falling wholesale costs.

This week, a 26-cent-per-litre reduction has effectively flowed through the system via government measures and a steady drop in Adelaide’s gate price. In the city, prices have already begun reflecting that shift. But here in Coober Pedy, it’s a very different story.

Diesel remains stubbornly fixed at $3.59 per litre across the town’s three main service stations.

That’s despite the Adelaide gate price now sitting around $2.73 per litre—a significant margin that raises serious questions about pricing practices in remote communities.

Adding to the frustration, a local witness has confirmed seeing a fuel delivery truck arrive at one of the town’s outlets earlier this week. That means at least one operator has taken on stock purchased at the reduced wholesale price.

At a bare minimum, that should translate to a 26-cent-per-litre drop at the bowser—and arguably more, given the broader decline in wholesale pricing.

Yet, there has been no movement whatsoever.

It remains unclear whether other outlets have also received new deliveries at the lower rate, but even if only one station has, basic market competition would normally see others follow suit quickly.

That hasn’t happened.

For locals and travellers alike, the lack of price adjustment is becoming increasingly difficult to justify. In a region where fuel is not a luxury but a necessity, delays in passing on cost reductions hit harder than they would in metropolitan areas.

With clear evidence that wholesale prices have dropped—and at least one confirmed delivery at the lower rate—the spotlight is now firmly on local operators to explain why Coober Pedy isn’t seeing the same relief as the rest of the state.

For now, the numbers don’t add up.
