Clare Petrol Climbs 17 Cents as South Australia Bucks the Eastern States Slide
A comprehensive analysis of this week's fuel pricing data reveals a clear regional split, with South Australia lifting at the bowser just as the eastern states ease back. As of early Monday afternoon on 1st June 2026, the standout story sits in the Mid North town of Clare, where unleaded petrol has climbed 17 cents to a five station average of 184.5 cents per litre.
Breaking down the numbers, Clare recorded one of the more notable unleaded petrol movements in the country this week, up from 167.5 cents only days earlier. Premium 98 in the same town followed suit, lifting 16.5 cents to 207.0 cents. For a regional centre that had been sitting comfortably below the 170 cent mark, that is a sharp move for local motorists filling the family car.
The eastern states are easing back
The data paints a clear picture of two very different markets. While Clare climbed, several suburbs in the eastern states moved firmly the other way. In Melbourne's north, Reservoir drivers saw unleaded fall to a 172.0 cent average, down a substantial 34.1 cents on the previous reading. Further south, North Geelong eased to 175.4 cents, while up in Queensland the Parkwood servos on the Gold Coast slipped to 171.4 cents. Across Victoria and Queensland, the pattern was one of relief at the pump.
Why Clare is bucking the trend
The move traces back to the well documented price cycle, where retail margins are rebuilt after a stretch at the bottom. Clare and similar regional centres across South Australia do not always move in step with the capital cities, and industry factors such as wholesale terminal gate prices, local competition and the timing of the cycle all play a part. Historical data suggests that when a regional town has spent a fortnight near the floor, an upswing of this size is usually the cycle resetting rather than any single market shock. Motorists in towns following Clare's lead would do well to keep an eye on the best time to fill up before the next increase lands.
A calmer story for diesel
Diesel lifted too, but only gently. South Australia added 7.9 cents overnight to a statewide average of 223.2 cents per litre, a modest 3.67 per cent rise that still leaves the state squarely in the middle of the national pack. By comparison, New South Wales averaged 222.6 cents and Victoria 223.1 cents, while at the far end of the scale the Northern Territory continued to run well clear of everyone at 280.9 cents.
For diesel drivers wanting value within South Australia, the regional centres again tell the most interesting story. Mount Gambier in the state's south east offered the cheapest diesel of any sizeable SA town, with a six station average of 205.6 cents and the lowest pump reading at 202.9 cents. Closer to the capital, Blair Athol in Adelaide's inner north posted a 206.2 cent average across its three monitored stations. Both sit well under the statewide figure, a reminder that the headline average rarely reflects what a careful shopper can actually find.
What it means for drivers
The Clare increase is a useful reminder of how quickly a regional market can turn. A driver who topped up there a few days ago would have paid close to 167 cents, while the same fill today costs roughly 184 cents, a difference of around 12 dollars on a 70 litre tank. For households across Adelaide and the Mid North, that gap is the difference between filling up on the right day and the wrong one.
The next question is whether the eastern states have found the bottom of their own cycle. With Reservoir, North Geelong and Parkwood all sitting in the low 170s, those markets are unlikely to fall much further before retailers begin rebuilding margins, the same process now playing out in Clare.
For motorists willing to shop around, the data this week reinforces an old lesson. Location and timing remain the two most important factors in fuel savings, and the gap between a regional town on the way up and a capital city suburb on the way down can be wider than many drivers realise.
