When is fuel cheapest in Brisbane?
Brisbane has no regular price cycle: its Diesel prices follow wholesale costs, so they tend to move a week or two after the terminal gate price.
On Fri 6 Nov the national terminal gate (wholesale) price was 257.0 c/L and the Brisbane city average 277.0 c/L, 20.0 c/L above it.
No weekday was the cheapest in most of the last 12 full weeks to : the Diesel weekday averages in Brisbane were within 0.6 c/L of each other once the overall price movement is removed.

How we forecast
FuelRadar has helped Australian drivers find cheaper fuel since 2020. Each estimate starts from Brisbane's reported daily city averages and how they have moved recently. A city daily average is FuelRadar's scheduled morning average of the city's reported station prices, the figure this page quotes for every capital. Where a city has a regular price cycle, the estimate projects that cycle; elsewhere it follows the recent trend, blended with the latest dated wholesale price change. Based on the Brisbane Diesel outlook, adjusted by 3.2 c/L using local price history. The likely range widens with each day ahead.
Next-day estimates missed by 0.4 c/L on average, closer than assuming prices stay the same (0.4 c/L).

Forecast questions
When will Diesel prices go down in Roma?
Estimate only (yesterday's outlook): Diesel in Roma is estimated to change little, to 270.3 c/L by Fri 20 Nov (likely 264.2–289.5), from 271.1 c/L estimated for Fri 13 Nov. Past 7-day estimates missed by about 4.5 c/L on average, only slightly less than assuming prices stay the same (4.7 c/L). The dated 30-day forecast shows a likely range, not a promised low date. Check current station prices before changing when you fill.
What is the best day to buy Diesel in Roma?
There is no fixed best day for Roma. Compare current reported station prices and their update times. A recent high or a lower estimate does not confirm a cheaper date.
How accurate is FuelRadar Australia's Diesel price outlook?
Not accurate enough yet to tell you to fill or wait, so we don't. From 10 Oct to 8 Nov our next-day Diesel forecasts for Brisbane were off by 0.4 c/L on average over 30 days checked. That beat assuming prices wouldn't move (0.4 c/L).
Do higher prices mean they will fall soon?
A recent high does not confirm a turnaround. Compare the reported movement with the estimated range. If that range still includes today's price, a fall is not established. Check current station prices before deciding to wait.
How often is the outlook updated?
We update the forecast overnight. For anything that changed today, check the map. While the update runs, we may show the previous forecast with its date.
