How we forecast

FuelRadar has helped Australian drivers find cheaper fuel since 2020. Each estimate starts from Port Augusta'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 (0.6 c/L).

Forecast questions

When will E10 prices go down in Port Augusta?

Estimate only (yesterday's outlook): E10 in Port Augusta is estimated to edge down about 2.0 c/L, to 220.7 c/L by Tue 17 Nov (likely 212.9–238.5), from 222.7 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 E10 in Port Augusta?

There is no fixed best day for Port Augusta. 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 E10 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 E10 forecasts for Adelaide 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 e10 prices go up tomorrow in Port Augusta?

Estimate only: FuelRadar's Port Augusta estimate for Wed 11 Nov is 222.0 c/L, down 0.7 c/L on the 222.7 c/L estimated for Tue 10 Nov. Next-day estimates for Port Augusta 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.

When will diesel prices go down in Port Augusta?

Diesel does not usually follow the petrol price cycle, so there is no regular low to wait for. The Port Augusta diesel city daily average was 279.7 c/L on Mon 9 Nov, down 3.5 c/L over 30 days. The national wholesale diesel price fell 9.7 c/L over the five days to Fri 6 Nov. FuelRadar names no date for a fall: the Port Augusta diesel forecast gives its day-by-day estimate and likely range.
