Price Trends by Fuel Type
While petrol prices are rising, diesel has seen the most aggressive movement this week. Premium fuels also continue to command a significant margin over regular unleaded.
| Fuel Type | National Average | Cheapest City | Cheapest Price | Most Expensive City | Highest Price |
|---|---|---|---|---|---|
| Unleaded 91 | 236.54 cpl | Geelong | 233.05 cpl | Darwin | 242.14 cpl |
| E10 Petrol | 233.06 cpl | Melbourne | 230.40 cpl | Wollongong | 235.78 cpl |
| Diesel | 280.04 cpl | Melbourne | 274.87 cpl | Wollongong | 283.23 cpl |
| Premium 95 | 251.98 cpl | Geelong | 246.94 cpl | Darwin | 257.60 cpl |

Looking Ahead
The immediate outlook for motorists is challenging. Based on current market indicators and the sharp increases recorded between 16 March and 22 March, we expect prices in major capital cities like Sydney, Melbourne, and Brisbane to remain near their peak for the next 7 to 10 days. The price cycle suggests that while we may be approaching the top of the curve, any relief at the bowser is likely 2 to 3 weeks away.
Regional areas may experience a delayed peak, meaning prices could continue to climb steadily over the next fortnight before stabilising. Diesel consumers should prepare for sustained high costs, as the global middle distillate market remains tight. We recommend that motorists who have not yet fueled their vehicles seek out the remaining lower-priced stations in their area before the full weight of the recent increases is felt at every service station.
