Weekly Fuel Report: 13 April 2026 to 19 April 2026

Motorists across Australia saw a welcome relief at the bowser this week as petrol and diesel prices continued their downward trajectory. This report provides a comprehensive analyse of the market movements and what drivers can expect in the coming weeks. Our data indicates that the majority of capital cities are currently in the falling phase of their price cycles, offering an opportunity to save on fueling costs if drivers time their visits to the service station correctly.

Current fuel prices and prediction

Downward Trend: Average petrol prices fell in every capital city over the last seven days, with Adelaide and Hobart recording the most significant drops of over 20 cents per litre (cpl).
Diesel Softening: After months of sustained high prices, diesel has finally begun to retract significantly, with the national average now sitting at 308.83 cpl.
Perth Value: Perth remains the most affordable capital city for Unleaded 91, averaging 206.82 cpl, followed closely by Adelaide.
Cycle Status: Sydney, Melbourne, and Brisbane are deep into the falling limb of their price cycles, meaning prices are approaching the expected quarterly low.

Price Trends by Fuel Type

National averages show a consistent downward trend across all major fuel categories, providing some relief for both commuters and the transport industry.

Fuel Type	National Average Price	Cheapest City	Most Expensive City	Overall Trend
Unleaded 91	213.56 cpl	Perth (206.82)	Darwin (217.26)	Falling
E10	210.33 cpl	Hobart (198.89)	Melbourne (213.64)	Falling
Diesel (DSL)	308.83 cpl	Perth (303.99)	Sunshine Coast (315.38)	Falling
Premium 95	229.44 cpl	Perth (222.95)	Darwin (233.91)	Falling

Looking Ahead

Over the next 3 to 4 weeks, we expect to see the current price cycles in Sydney, Melbourne, and Brisbane reach their lowest points before the inevitable "spike" phase begins. Motorists in these cities should look to fill their tanks within the next 7 days to take advantage of the bottom of the cycle.

In Adelaide and Perth, where cycles are shorter, prices will likely fluctuate more rapidly. We anticipate that diesel prices will continue to soften, though at a slower rate than petrol, as global supply chain pressures ease. Regional areas may take longer to see these price drops reflected at the pump due to the time it takes for new, cheaper stock to be delivered to the centre of these communities.
