Canberra Diesel Barely Moves While NSW Cops a 16 Cent Jump Right Next Door

Right, so here's something that caught my eye this morning. Canberra diesel is sitting in this ridiculously tight band right now, with barely 5 cents separating the cheapest servo from the dearest. Meanwhile, just up the highway in NSW, diesel has jumped nearly 16 cents overnight. If you live in the ACT, you're having a pretty good week. If you're anywhere else, well, keep reading.

The ACT is basically a flat line

Across all 22 diesel stations in Canberra, the cheapest price today is 284.9 cents a litre and the most expensive is 289.9. That's a 5 cent spread across the entire territory. Five cents. You could drive to any servo in the ACT right now and know you're paying within a couple of bucks of what everyone else is paying for a full tank.

Now compare that to what's happening in other states and you'll see why this is worth talking about.

NSW just copped it

New South Wales diesel has climbed 15.8 cents overnight to an average of 293.7 cents a litre. That's across more than 1,000 stations. The cheapest you'll find in the state is 225 cents down in places like Marulan on the Hume Highway, where four stations are averaging about 285. But the dearest is pushing 339 cents. That's a 114 cent spread from top to bottom.

Think about that for a second. In Canberra, every servo is within a beer's worth of each other. In NSW, the difference between the cheapest and most expensive diesel is enough to buy you a slab.

Places like Greenacre in Sydney's southwest are sitting around 285 on average, and North Albury down on the border is about the same at 286. But if you're filling up at the wrong spot in regional NSW, you could be paying 50 or 60 cents more than someone in the next town over. That's where the planning comes in.

The rest of the country is all over the shop

Here's what the national picture looks like for diesel right now:

Victoria is averaging 288.6 cents with a 120 cent spread. Suburbs in Melbourne's southeast like Clayton South have servos as low as 189.9, which is genuinely cheap. But you've also got places pushing past 310. The outer suburbs are worth checking if you're doing a big fill. Noble Park and Cranbourne West are both hovering around 277 to 280, which is decent given the state average.

Western Australia is at 292.7 on average, and the spread is massive at 130 cents. Regional towns like Kununurra are seeing prices anywhere from 199.5 to 330.3 depending on which servo you pull into. That's a 130 cent difference in the same town.

Tasmania is averaging 290.9 with a 149 cent spread. Smithton up on the northwest coast still has a servo at 189.9, but others in the same town are pushing close to 300. Worth shopping around if you're up that way.

And then there's the Northern Territory, which is in a league of its own. Average diesel is 290.4, but the spread is a staggering 251.7 cents. Some servos out near Mataranka have diesel at 199, while others in remote communities are charging 399. That's not a typo. Almost four dollars a litre for diesel.

Why Canberra is different

The ACT is a small market with a handful of stations, and they all tend to move together. There's not much point in one servo undercutting the others by 20 cents when every driver in town can see the competition from the next set of lights. It creates this natural price uniformity that you just don't get in bigger states with hundreds of kilometres between stations.

It also means Canberra motorists don't need to spend their arvo driving around comparing prices. The savings from shopping around in the ACT might buy you a flat white at best. In NSW or Victoria, the savings from picking the right suburb could buy you a week's worth of coffees.

What to do about it

If you're in the ACT, honestly, just fill up wherever's convenient. You're not losing out.

If you're in NSW after this 16 cent jump, it's worth checking suburbs like Greenacre or Marulan before filling up at whatever servo is closest to home. The difference could be 50 cents a litre or more depending on where you are.

For everyone else, the outer suburbs and regional competition spots are still your best bet. Clayton South in Melbourne at 189.9 is hard to beat anywhere in the country right now.

Look, end of the day, a 5 cent spread might not sound exciting, but when the rest of Australia is swinging by hundreds of cents, Canberra's little flat line is actually something to be jealous of. More cash in your pocket for the important stuff. Can't argue with that.
