Hawker Petrol Climbs 33 Cents While Clare Coffin Bay and Murray Bridge Join the Regional SA Price Jump

Right, if you're filling up anywhere in regional South Australia today, pull up a chair because you're not going to like this one. As of 21st Apr 2026 8:14am ACST, four regional SA towns have all copped notable petrol price increases in the last 24 hours, and the biggest jump I've seen in ages is sitting up in the Flinders Ranges at Hawker.

Here's the thing, right. Unleaded at Hawker has climbed from 213.4 cents yesterday to 246.4 cents this morning. That's a 33 cent jump in a single day across five stations. Fair dinkum, when a country town moves that hard overnight, you know the price cycle is having a moment.

Four Regional SA Towns Cop It at Once

This isn't just a Hawker story. Look at what's happened across the state:

Four regional towns, four different corners of the state, all moving in the same direction on the same morning. That's not a coincidence, that's a price cycle doing what price cycles do. The question is when the metro mob in Adelaide catches up.

Where the Price Cycle Lands in SA

Now, you'd be mad not to understand how this works. Regional SA towns often move a day or two ahead of Adelaide metro on the upward swing because they've got fewer servos to absorb the shock. One or two operators shift their board and the whole suburb average climbs with them.

Adelaide metro unleaded is still sitting comfortably in the mid 190s to low 200s, which means if you're heading out of town for the long weekend you want to top up before you leave. Reckon that's worth about 30 bucks on a 60 litre tank if you fill at Hawker instead of your local Adelaide servo.

Worth keeping an eye on Mount Gambier and Whyalla too. Those bigger regional centres sometimes hold the line a bit longer, but once they move they move hard.

Diesel Is Climbing Across the Whole State

While we're here, the diesel story in SA is also worth mentioning. Statewide diesel has climbed 8.1 cents in 24 hours, with the average now sitting at 301 cents a litre across 357 stations. That's the highest state diesel average in mainland Australia right now, with Queensland on 298.6 cents and NSW at 298.7 cents snapping at their heels.

For comparison, diesel in Western Australia has actually dropped 11.2 cents to 289 cents a litre, and Victoria has eased 6.9 cents to 295.6 cents. So the tradies and truckies heading across the Nullarbor are getting a nice surprise the further west they roll.

The cheapest diesel you'll find in the SA network this morning is 269.9 cents at a handful of regional stations, while the most expensive is hitting 350 cents out in the outback. That's an 80 cent spread, which tells you exactly how brutal the geography tax gets once you're more than a few hours from a port or a refinery.

What Davo Reckons You Do

Here's my take. If you're in regional SA and you filled up yesterday, cop it sweet and move on. If you haven't filled yet this week, get into it this arvo before the price climb works its way across more suburbs.

If you're an Adelaide metro driver watching this play out, check the board before you commit. A few of the better servos in Blair Athol, Enfield and the western suburbs are still doing the right thing by locals with unleaded under 200 cents. But once the cycle lands properly, those sub 200 prices won't stick around.

And if you're planning a road trip to Coffin Bay or the Flinders Ranges over Easter, factor the extra 30 cents a litre into your budget. A tank and a half at regional prices compared to Adelaide prices is the difference between a decent pub feed and a servo pie and a can of Solo.

Check your local board on the interactive fuel map before you fill, because the servo one street over might be 10 cents cheaper for no reason other than how the cycle has landed. Fair dinkum, the difference between a smart fill and a dumb fill this week is a couple of clicks on your phone.

Look, end of the day, regional SA is going through a price cycle spike and the smart move is to pay attention for a few days. Can't argue with that.
