Weekly Fuel Price Report: 6 April to 12 April 2026
Welcome to the FuelRadar weekly fuel report for the week ending 12 April 2026. Over the past week, Australian motorists have experienced a significant divergence in fuel price trends at the bowser. While petrol prices across all grades (Unleaded 91, E10, Premium 95, and Premium 98) have seen steady declines across our major centres, diesel prices have unfortunately continued to climb, putting additional pressure on transport, freight, and diesel vehicle owners.
Current fuel prices and prediction
- Petrol prices are falling: Unleaded 91 prices fell by an average of 4 to 8 cents per litre (cpl) across major capitals, with Sydney experiencing the largest drop of 8.38 cpl (-3.69%).
- Diesel continues to rise: Diesel prices are rising nationally, increasing by up to 15 cpl in regional centres like Hobart and Townsville, driven by ongoing global diesel supply constraints.
- Cheapest fuel: Perth currently holds the title for the cheapest Unleaded 91 in the country at an average of 222.05 cpl, closely followed by Canberra and Adelaide.
- Most expensive fuel: Darwin remains the most expensive capital for Unleaded 91, averaging 228.45 cpl, while the Sunshine Coast recorded the highest diesel prices at 322.43 cpl.
- Prediction: We expect the downward cycle for regular unleaded to continue for another week in the major Eastern capitals before bottoming out. Conversely, diesel is expected to remain elevated in the short term.

Price Trends by Fuel Type
Looking at the national averages, we can see a clear divide between the falling prices of petrol blends and the rising costs associated with diesel fuels.
| Fuel Type | National Average | Cheapest Market | Most Expensive Market | Overall Trend |
|---|---|---|---|---|
| Unleaded 91 | 224.25 cpl | Perth (222.05 cpl) | Darwin (228.45 cpl) | Falling |
| E10 | 220.63 cpl | Hobart (213.33 cpl) | Melbourne (224.00 cpl) | Falling |
| Premium 95 | 239.91 cpl | Geelong (237.48 cpl) | Darwin (245.33 cpl) | Falling |
| Premium 98 | 249.75 cpl | Adelaide (247.79 cpl) | Darwin (263.76 cpl) | Falling |
| Diesel | 317.34 cpl | Geelong (314.15 cpl) | Sunshine Coast (322.43 cpl) | Rising |
| Premium Diesel | 318.18 cpl | Melbourne (315.73 cpl) | Central Coast (319.88 cpl) | Rising |
| E85 | 235.17 cpl | Brisbane (232.76 cpl) | Townsville (241.33 cpl) | Falling / Stable |
Looking Ahead
Over the next 3 to 4 weeks, we anticipate that the regular unleaded price cycles in the major Eastern capitals (Sydney, Melbourne, and Brisbane) will continue their discounting phase. Motorists in these cities should hold off on filling their tanks entirely if possible, as we expect prices to reach the bottom of their respective cycles towards the end of April. Once the bottom is reached, be prepared for a sharp cyclical spike.
In Perth, the regular price cycle will continue to offer predictable savings, and motorists are advised to align their fuelling schedules with the cheapest days of the local cycle.
Unfortunately, for those driving diesel vehicles, there are no immediate signs of relief. International benchmark prices for refined diesel remain high, and seasonal demand pressures mean that diesel prices are likely to hover around or above the 315 to 320 cpl mark nationally for the remainder of the month. Transport and logistics operators should factor these sustained high costs into their short-term budgeting.
