AIP weekly report · week ending 18 October 2026- Darwin U91 rose 2.2 c/L from the week ending 11 October 2026 (246.8 c/L).
- At 249.0 c/L, Darwin was the 2nd dearest of the 8 capitals for U91, 6.9 c/L higher than the national average (242.1 c/L).

- Diesel averaged 288.7 c/L, 39.7 c/L more than U91; it fell 1.5 c/L on the week before.
Darwin doesn't follow a regular cycle the way the southern capitals do, so there's no predictable peak-and-trough pattern to time a fill against. Freight costs, given the distances involved in supplying the Top End, tend to keep prices elevated compared with the larger mainland cities.
The Northern Territory's MyFuel NT publishes reported station prices, so you can still compare boards across the city and find the cheaper options near you even without a cycle to plan around.
