FuelRadar Weekly Fuel Price Report
Date: 17 April 2026
Report Period: 6 April 2026 to 12 April 2026
Introduction
Welcome to the FuelRadar weekly fuel report. As we analyse the pricing data for the week ending 12 April 2026, Australian motorists will be pleased to recognise a widespread downward trend in petrol prices across the nation. However, those fuelling up with diesel will continue to face challenges at the bowser, as diesel prices have travelled upward in all major centres. Whether you are driving across the harbour or heading to the centre of town, understanding these cycles is key to helping you optimise your weekly budget.
Current fuel prices and prediction
This week's data reveals a distinct split in the market between petrol and diesel fuels. Here are the key highlights from across the country:
- Petrol Prices Falling: Unleaded 91 (U91) prices have dropped consistently across all monitored cities, with decreases ranging from 2.13% in Adelaide to 3.69% in Sydney.
- Diesel on the Rise: Conversely, standard and Premium Diesel (PDSL) prices are rising everywhere. Townsville experienced the sharpest jump, with standard diesel rising by 15.86 cpl (5.17%).
- Cheapest Capital for Petrol: Perth currently boasts the cheapest U91 among the capital cities at an average of 222.05 cpl, closely followed by Canberra at 222.47 cpl.
- Most Expensive Capital for Petrol: Darwin remains the most expensive capital city for U91, averaging 228.45 cpl.
- Premium Fuels Tracking Downward: Premium Unleaded fuels (P95 and P98) have mirrored the standard unleaded trend, falling by roughly 2% to 3.5% across all locations.

Looking Ahead
Over the next three to four weeks, we expect the current petrol price cycle to continue its downward trajectory in the major eastern capitals, including Sydney, Melbourne, and Brisbane. Motorists in these centres should hold off on filling their tanks completely if possible, as prices are likely to drop further before the cycle bottoms out and inevitably resets to a higher point.
In Perth, the regular weekly price cycle remains in effect. We advise timing your purchases for the cheapest days of the week to maximise your savings.
Unfortunately for drivers of diesel vehicles, global supply pressures and seasonal demand suggest that diesel prices will remain elevated. We do not anticipate a significant drop in diesel prices in the near term. Because diesel does not follow the same aggressive discounting cycles as petrol, it is crucial to remain vigilant and shop around for the best local deals.
