NSW Fuel Prices – Week of 31 August 2026

Prices in NSW haven't found the brakes yet. Unleaded U91 metro averaged 203.8 c/L this week, marking five consecutive weeks of rises — and the daily data suggests the climb isn't slowing down. If you've felt like every trip to the servo costs a little more than last time, that's because it does.

NSW Petrol Prices: Key Movements This Week

Metro U91 started the week at a relatively gentle 202.1 c/L on Monday, held fairly steady through Tuesday and Wednesday, then climbed sharply from Wednesday onward. By Saturday, metro U91 had pushed up to 205.6 c/L — a rise of 3.5 c/L across just four days. Rural drivers felt it too, with prices moving from 207.8 c/L at the start of the week to 209.8 c/L by Saturday.

P95 rose by 1.1 c/L in rural areas, slightly outpacing the metro movement. Diesel was the steadier mover, with just a 0.5 c/L increase on both sides of the divide. Still, at 249.4 c/L metro and 254.9 c/L rural, diesel is carrying a 45.6 c/L premium over U91 — that's a significant slug for utes, vans, and anyone towing.

Cheapest and Priciest Fuel in NSW Metro This Week

The spread between the cheapest and most expensive metro stations this week is striking. The cheapest metro station came in at 173.5 c/L, while the priciest hit 231.9 c/L — a gap of 58.4 c/L. That's not a rounding error, that's real money.

Brand averages tell a similar story. Among brands with three or more stations, Prime averaged just 195.9 c/L and Metro Fuel came in at 196.8 c/L across 89 stations. Meanwhile, BP averaged 208.3 c/L and Ampol Foodary averaged 208.6 c/L across 82 stations. A 12.7 c/L difference between the cheapest and priciest major brands means a 50-litre fill can cost you over $6 more depending solely on where you stop.

What Last Week's Daily Data Tells Us

Last Monday, 31 August, was the cheapest day to fill up, with metro U91 sitting at 202.1 c/L. Prices were still relatively contained through Tuesday and Wednesday before the mid-week surge kicked in. Knowing that pattern — steady early, rising later — is useful context heading into the week ahead.

NSW Metro Petrol Price Forecast: Next 3 Days

The near-term outlook for metro NSW isn't encouraging. Against the current metro U91 price of 203.8 c/L, the forecast sees prices climbing to 205.8 c/L on Sunday (78% confidence), 206.7 c/L on Monday (71% confidence), and 207.5 c/L by Tuesday (65% confidence). That's a projected rise of up to 3.7 c/L from where we are now, within metro areas.

How to Keep Your Fuel Costs Down in NSW

NSW is sitting 1 c/L below the national metro U91 average of 204.8 c/L, which offers a sliver of comfort — but only if you're filling up at the right places. Given the brand spread of nearly 13 cents and a station spread pushing 58 cents, where you fill up matters far more than which state you're in.

If you can get to a station averaging closer to 196 c/L rather than pulling into the nearest BP or Ampol Foodary, you're saving real money on every tank. With prices forecast to keep climbing over the next few days, filling up sooner rather than later is the smarter move for metro drivers.
