How we forecast

FuelRadar has helped Australian drivers find cheaper fuel since 2020. Each estimate starts from Sunbury'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. The likely range widens with each day ahead.

Next-day estimates missed by 0.6 c/L on average, no better than assuming prices stay the same (0.7 c/L).

Forecast questions

When will Diesel prices go down in Sunbury?

Estimate only (yesterday's outlook): Diesel in Sunbury is estimated to edge down about 1.5 c/L, to 274.3 c/L by Tue 17 Nov (likely 266.9–295.5), from 275.8 c/L estimated for Tue 10 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 Sunbury?

There is no fixed best day for Sunbury. 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 Melbourne were off by 0.6 c/L on average over 30 days checked. Assuming prices wouldn't move was just as close.

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.

Will diesel prices go up tomorrow in Sunbury?

Estimate only: FuelRadar's Sunbury estimate for Wed 11 Nov is 274.7 c/L, down 1.1 c/L on the 275.8 c/L estimated for Tue 10 Nov. Next-day estimates for Sunbury missed by 0.6 c/L on average over 30 days checked, about the same as assuming prices stay the same. Check current station prices before you wait to fill.

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.
