Labrador Diesel Holds at 263.9 While Queensland Sidesteps a 16 Cent Interstate Lift
According to pricing data collected at 2:00pm AEST on 18th Sep 2026, Friday's diesel pricing has split along the state borders. New South Wales and Victoria have both recorded diesel increases of more than 15 cents a litre in a single day, while Queensland has drifted slightly lower. For diesel drivers north of the Tweed, that quiet result is the story.
Queensland eased while the south lifted
Across 1,042 Queensland stations reporting diesel, the state average sits at 279.3 cents a litre, down 1.1 cents on yesterday's 280.4. On its own that is an ordinary day. The interest is in what happened elsewhere over the same 24 hours.
New South Wales diesel lifted 16.0 cents to 280.2 across 1,182 stations, a rise of just over 6 per cent. Victoria moved 15.3 cents higher to 277.6 across 1,034 stations. Both states were sitting well below Queensland yesterday, at 264.2 and 262.3 respectively. Today New South Wales has moved above Queensland on the state averages, and Victoria has closed most of the gap.
South Australia followed the Queensland pattern, easing 1.9 cents to 279.5 across 372 stations. Western Australia recorded the largest fall in the country at 9.6 cents, taking its average to 274.3 and giving it the cheapest state figure for diesel. Tasmania lifted a more modest 3.3 cents to 282.0.
Yesterday Queensland was one of the dearer mainland states for diesel. Today it sits in the middle of the pack without its own prices having done much at all.
Where Queensland diesel is cheapest
The state figure hides the detail that matters at the pump, and the suburbs at the cheap end are worth a look.
Labrador on the Gold Coast is the standout. All three stations reporting diesel there are listed at exactly 263.9 cents, a spread of zero. That is 15.4 cents under the state average, and it means a Labrador driver does not need to shop between servos to get the best local price. A 60 litre fill at 263.9 comes in around $9.24 cheaper than the same fill at the Queensland average.
Hemmant, on the industrial fringe of Brisbane near the port, averages 266.6 cents across three stations, with the cheapest at 259.9 and the dearest at 274.9. That 259.9 is the lowest single price among the three Queensland suburbs in today's rankings, though the spread means the cheapest site is worth seeking out.
Further north, Monkland on the edge of Gympie averages 267.3 across three stations, ranging from 260.9 to 278.9.
Across the border in South Australia, the cheapest diesel towns are just as steady. Tintinara on the Dukes Highway averages 264.9 with a tight 5.9 cent spread, while Gladstone in the Mid North averages 265.6 with a cheapest price of 260.0.
What moved in the south
The Victorian lift was broad rather than isolated. Hamilton diesel rose 24.4 cents to 278.6 across nine stations, Langwarrin lifted 20.5 cents to 283.0, and Wodonga on the New South Wales border moved 16.1 cents higher to 281.0. Metropolitan suburbs including Frankston and Preston recorded increases between 16 and 19 cents. Premium diesel in Epping lifted 29.6 cents to 288.3 across nine stations.
Our data does not show the cause, so we will not guess at one. What it does show is that a move of 15 to 16 cents in one day across more than 1,000 stations in each state is not the signature of local competition. When unleaded moves in step like this it is usually the discount cycle resetting. Diesel does not follow that retail cycle in the Australian capitals, which is why a day like this stands out.
Queensland's own range is wide. Diesel runs from 249.7 at the cheapest station to 348.0 at the dearest, a spread of 98.3 cents, so the state average tells only part of the story.
What it means at the bowser
For Queensland diesel drivers with a fill due in the next few days, the current pricing at Labrador, Hemmant and Monkland sits well under the state average and well below what drivers in New South Wales and Victoria are now paying. Keep an eye on the diesel prices page and the price trends tool for any sign that the interstate lift is crossing the border.
Location and timing remain the two levers that matter in fuel savings. In Queensland this week, being on the right side of the border counts for more than it has in some time.
