Weekly Fuel Report: 20 June 2026 to 26 June 2026
Introduction
The overall fuel price situation for the week ending 26 June 2026 brings welcome relief to motorists across Australia. As we analyse the data from the past week, we can recognise a definitive downward trend in both petrol and diesel prices across almost all major capital cities and regional centres. The national average for Unleaded 91 (U91) now sits at 162.39 cents per litre (cpl), reflecting softer international wholesale markets and a favourable exchange rate. Whether you are commuting in the city or traveling across the country, this week offers an excellent opportunity to save at the bowser.
Current fuel prices and prediction
- Widespread Discounting: All major capital cities are currently in the discounting phase of their respective price cycles. Sydney, Melbourne, and Brisbane have all recorded drops of over 5 cpl for U91.
- Cheapest Capital: Adelaide currently offers the cheapest U91 petrol in the country at an average of 152.69 cpl, having fallen by 3.55% over the past week.
- Most Expensive Capital: Canberra remains the most expensive capital city for U91 at 167.95 cpl, though it is still experiencing a gradual decline (-1.33%).
- Diesel Relief: Diesel drivers are seeing significant savings across the board. The national average for diesel has fallen to 186.72 cpl. Regional centres like Geelong saw massive diesel price drops of up to 14.04 cpl (down 7.47%).
- Prediction: We anticipate that the current falling trend will continue for the next few days in the eastern capitals before prices hit the bottom of their cycle.

Looking Ahead
Over the next 3-4 weeks, we expect the current discounting cycle in the major eastern capitals (Sydney, Melbourne, and Brisbane) to reach its lowest point within the next 7 to 10 days. Motorists planning any traveling should aim to fill up their tanks during this window to optimise their savings. Following this trough, historical data suggests a sharp price hike will occur as the cycle resets.
In Perth, where the petrol price cycle operates on a strict weekly schedule, prices will remain predictable, with the cheapest days to fill up typically falling in the middle of the week. Meanwhile, regional centres and cities with less volatile cycles, such as Canberra, Hobart, and Darwin, will likely see a continued, slow decline, passing on the recent drops in wholesale costs to local consumers.
