Yarraman Diesel Holds at 197 Cents While Toowoomba Climbs 19 and Queensland's Regional Map Splits in Two
Diesel in Yarraman is holding at 197.9 cents per litre this afternoon, while Toowoomba Regional further south has jumped 19.2 cents over the same 24 hours. Captured at 2:06pm AEST on 26th May 2026, that gap is the clearest snapshot yet of how split Queensland's diesel market has become.
Across Queensland the statewide diesel average has lifted 5.6 cents to 231.4 cents per litre. Yet a small cluster of regional towns north of Brisbane is still posting prices that look like they belong to a different state.
The 152 Cent Spread
Queensland is currently the most polarised diesel market in mainland Australia. The numbers show a spread of 152.2 cents between the cheapest and most expensive bowser in the state, with the floor at 197.7 cents and the ceiling at 349.9 cents. That gap is wider than New South Wales (146.0), Victoria (151.5) and South Australia (128.4).
Look at where those cheap prices are sitting, though. Not in the metropolitan corridor between Brisbane and the Gold Coast where competition is usually fiercest, but up in the timber country and dairy belt north and west of the capital.
The Sub 200 Cent Cluster Around Gympie
Four regional postcodes are responsible for Queensland's cheap diesel reputation right now:
- Monkland, three stations averaging 207.8 cents with the cheapest at 197.7
- Yarraman, three stations sitting in a tight 2 cent band between 197.9 and 199.9 cents
- Gympie, four stations averaging 214.6 cents with the cheapest at 199.7
- Gympie Regional, four stations averaging 214.8 cents
Yarraman is the standout. A 2 cent spread between cheapest and dearest is the tightest of any Queensland diesel market in the dataset. When every station within a postcode prices inside a 2 cent band, it usually means one of two things: a single dominant wholesale supplier, or a motorist base small enough that price discipline holds. Either way, drivers passing through the South Burnett on the New England Highway are getting a notably consistent deal.
Monkland is worth a closer look too. At 197.7 cents, it is the cheapest diesel station in the state.
Toowoomba and Lockyer Valley Move the Other Way
The contrast on the western side of Brisbane is more pronounced. Toowoomba Regional diesel has climbed 19.2 cents in 24 hours, with the average across five stations rising from 214.9 to 234.1 cents per litre. Further down the Range, Lockyer Valley Regional has climbed 21.6 cents, with six stations now averaging 241.5 cents after sitting at 219.9 yesterday.
That is a substantial single day move. For a Toyota HiLux owner topping up an 80 litre tank, the difference between filling at Yarraman versus Lockyer Valley right now works out to roughly $35. Across a working fleet of half a dozen utes refilling weekly, the gap compounds quickly.
The Warrego Highway corridor between Brisbane and Toowoomba has historically tracked the metro average reasonably closely. The fact that it has decoupled by more than 20 cents in 48 hours suggests one of the wholesale loads in the region has repriced, while the South Burnett supply chain has not.
What the State Average Hides
The single 231.4 cent statewide figure puts Queensland third cheapest in mainland Australia, behind South Australia (230.7) and just ahead of New South Wales (231.3) and Western Australia (233.3). But the cheapest individual price in Queensland (197.7) is actually below the cheapest in either New South Wales (199.9) or South Australia (211.5). The headline average hides the bargain.
For a fuller picture of where the cheap fills are hiding nationally, the latest diesel prices data is worth a regular look.
The Takeaway for Queensland Motorists
If your route takes you up the Bruce Highway or through the South Burnett this week, Monkland and Yarraman are where the value sits. If you are doing the Toowoomba run, today is not the day to fill up at the bottom of the Range, and waiting a day or two for the rise to settle could save five to ten cents per litre.
Statistically speaking, the Queensland diesel market is splitting along a north south axis rather than the more familiar metro versus regional divide. Worth noting for anyone planning a long haul this week.
The numbers are clear: where you fill up matters as much as when you fill up.
