Tasmania Diesel Falls Nearly 10 Cents as Western Australia and South Australia Push the National Map Higher
Diesel in Tasmania has fallen 9.8 cents overnight to 227.7 cents per litre, the sharpest daily drop of any state. Captured at 8:14am AEST on 2nd June 2026, that move runs against almost everywhere else on the map. While most of the mainland climbed over the past 24 hours, Tasmania went firmly the other way.
That is a fall of 4.13 percent from 237.5 cents the day before, the kind of overnight movement worth noting for anyone running a diesel south of Bass Strait.
The mainland tells a different story
The past 24 hours show most states moving up:
- Western Australia: up 19.2 cents to 225.4, the largest daily rise nationally at 9.31 percent
- South Australia: up 11.1 cents to 223.6, a rise of 5.22 percent
- Queensland: up 6.5 cents to 224.5, or 2.98 percent
- New South Wales: broadly flat at 221.9, up just 0.7 cents
- Victoria: easing to 220.5, down 3.8 cents
Western Australia and South Australia are driving most of that national movement. WA in particular posted the steepest single day increase, which often signals the upswing phase of the wholesale cycle working its way through to the bowser.
Why Tasmania is bucking the trend
Tasmania is a smaller and more contained market, with around 44 stations reporting diesel prices, so its averages tend to move in larger steps than the bigger mainland states. The cheapest diesel in the state was recorded at 207.9 cents, roughly 20 cents below the state average, which shows there is still meaningful variation worth shopping around for.
For motorists in Hobart and Launceston, the takeaway is simple. When a small market like Tasmania records a notable fall, the window to lock in the lower price can be short, so it pays to fill up while the trend is in your favour.
The national extremes
At the other end of the scale, the Northern Territory is still the most expensive place to buy diesel by a substantial margin. NT averaged 280.4 cents, well above every other state and a reminder of how freight distances and remoteness shape pricing for drivers in Darwin and beyond.
On the cheaper side, Queensland and Victoria both held their state averages comfortably under the 225 cent mark despite the broader upward pressure, and Victoria was one of only two states to record a fall.
The takeaway for diesel drivers
This is a notable shift from the calm of recent weeks, and it shows how regional Australia's diesel prices can move independently of one another on any given day. A few things stand out:
- Tasmania's fall may not last long given how quickly small markets can reverse, so southern drivers should act while prices are soft
- WA and SA drivers are at the wrong end of a rising cycle and may benefit from timing their next fill carefully
- The gap between the cheapest and most expensive states now sits at more than 50 cents per litre, a wide spread by any measure
You can track current diesel prices in your area and compare stations across the country, and if you are unsure when to buy, the best time to fill up guide breaks down the weekly patterns by state.
The numbers are clear. Diesel drivers in Tasmania have caught a genuine break this week, while those in the west and in South Australia are facing the steepest rises in the country. As always, a quick check before you pull into the servo can be the difference between a good fill and an expensive one.
