How we forecast
FuelRadar has helped Australian drivers find cheaper fuel since 2020. Each estimate starts from Launceston'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 Launceston Premium diesel outlook, adjusted by -2.1 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, no better than assuming prices stay the same (0.4 c/L).

What is the best day to buy Premium diesel in Newnham?
There is no fixed best day for Newnham. 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 Premium 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 Premium diesel forecasts for Launceston were off by 0.4 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.
How often is the outlook updated?
We update the forecast overnight. For anything that changed today, check the map.
