Petrol Under Two Dollars Returns to Roma and Mount Gambier While the Capitals Pay More
I've spent most of August writing about refinery shutdowns, emergency fuel plans and billion dollar diesel reserves. Heavy going, even by my standards. So here's a change of pace for the last day of winter. As of 8am AEST this morning, 31 August 2026, you can buy unleaded for under two dollars a litre in at least two Australian towns, and neither is anywhere near a capital city.
Roma, around 480 kilometres west of Brisbane, is showing unleaded at 199.6 cents after a 6.3 cent fall. Mount Gambier, the South Australian town famous for a crater lake that turns a vivid blue each summer, has slipped to 199.8 cents, down 8.1 cents. Two towns more than 1,400 kilometres apart, both back under a mark plenty of motorists assumed was gone for good.
To put this in perspective, the full fuel excise came back on 3 August and added almost 19 cents a litre in tax. For pump prices to be falling through the two dollar barrier anyway, the wholesale price underneath has to be genuinely easing. That's the real story here, and it's playing out right across regional Queensland and South Australia.
The bush is winning this round
Regional towns don't ride the sawtooth price cycles capital city drivers know so well. Their prices track the terminal gate rate, which is what fuel costs as it leaves the storage terminal, plus freight and a retail margin. When wholesale eases, country prices drift down gradually instead of waiting for a cycle reset.
And drift down they have. Diesel in Dalby has come back 8.3 cents to an average of 248.6. Charlton, on the western edge of Toowoomba, is down 6.6 cents to 249.3. Unleaded in Bowen eased 5.7 cents to 221.2, and premium 98 in Gympie fell 7.5 cents to 227.4. Different fuels, different corners of the state, same direction of travel.
Now look at the south east. Diesel in Caboolture moved up 5.8 cents to 253.7, and premium 98 in Labrador on the Gold Coast added 6.2 cents to 221.7. No contradiction there. That's the Brisbane cycle doing what cycles do while inland prices quietly follow the wholesale market down.
Mount Gambier deserves its own paragraph. Alongside unleaded under two dollars, premium 98 there has fallen 13.1 cents to 221.8, and local diesel averages 244.5 cents against a statewide South Australian figure of 257.4. One regional centre beating its state average across three fuel grades at once doesn't happen often, and I'd wager a few Adelaide drivers heading down for the school holidays will notice the difference.
Enjoy it while it lasts
What most people don't realise is how unusual this moment is. Australia has been running on a single operating refinery since Lytton went offline at the start of August, the excise is back at full strength, and yet parts of regional Queensland and South Australia are paying less than they were a fortnight ago. Wholesale relief is arriving even while everything else pushes the other way.
The practical upshot for your wallet is straightforward. If you're in Roma or Mount Gambier, an 8 cent fall is worth roughly five dollars on a 60 litre fill, so this is a good week to run the tank down and then fill it properly. If you're in the south east corner of Queensland, the cycle is heading the other way, so timing matters more than usual. Checking live unleaded petrol prices before you drive past a servo takes about ten seconds, and the price trends page will tell you whether your town is on the way up or on the way down.
Fair to say the fuel industry rarely hands out good news at the end of winter. When it does, take it. And keep half an eye on those wholesale numbers, because whatever regional Australia is enjoying this week tends to reach the capitals eventually, one cycle at a time.
