WA Fuel Prices – Week of 8 June 2026

Perth drivers have had three consecutive weeks of relief at the register, with metro U91 easing again to 165.1 c/L, sitting 1.7c below the national metro average of 166.8 c/L. That's a quietly encouraging run, and the trend looks set to continue.

WA Fuel Prices Snapshot: 8–15 June 2026

Biggest Movers in WA This Week

Diesel was the standout mover, dropping 5.6c in metro and 4.1c in rural areas. That's a meaningful saving for tradies and freight operators, though metro diesel at 194.1 c/L still sits 29c above metro U91, a gap wide enough to keep cost-conscious diesel drivers paying close attention to where they fill up.

P98 also had a notable week, but not without drama. Metro P98 spiked sharply from 186.2c on Monday to 194.1c by Wednesday, before pulling back steadily to close at 188.0c on Sunday. If you topped up mid-week without checking prices first, you likely paid a dollar or two more per tank than necessary.

U91 followed a similar rhythm. Prices climbed from 161.8c on Monday to 169.6c by Wednesday, then retreated for the remainder of the week, settling at 163.5c by Sunday. That mid-week peak is a pattern worth watching, because it repeated across multiple fuel types this week.

WA Metro Price Range: How Much Shopping Around Saves

The spread between the cheapest and priciest metro stations this week was enormous. Costco Casuarina averaged 148.7 c/L for U91, while the most expensive metro station, Independent Hills Emporio, sat at 216.9 c/L. That's a 68.2c gap on the same fuel in the same city. For a 60-litre tank, that difference is over $40.

Brand averages tell a similar story. Solo averaged 154.0c, Burk 154.9c, and Metro Petroleum 155.5c for metro U91. At the other end, Independent stations averaged 191.6c, a gap of nearly 37c per litre compared to Solo. Even moving a few kilometres to a cheaper brand can save you real money over time.

Cheapest Day to Fill Up Last Week

Last Monday, 8 June, was the cheapest day of the week for metro U91, with prices averaging 161.8 c/L. Drivers who waited until Wednesday paid closer to 169.6c. That mid-week spike is a good reminder that price-checking before you leave home isn't just for the budget-conscious, it's just smart driving.

WA Metro Petrol Price Forecast: Next Three Days

The outlook for metro U91 is encouraging. Prices are forecast to ease from the current 165.1 c/L down to 162.1c on Monday (78% confidence), 161.3c on Tuesday (71% confidence), and 160.5c by Wednesday (65% confidence). If those forecasts hold, metro Perth could be flirting with 30-day lows in the coming days.

How to Save on Fuel in WA Right Now

The current 165.1 c/L metro average is sitting comfortably below the 30-day high of 216.9c, and the trend is still pointing downward. Rural drivers are still paying a painful 33.3c premium over metro for U91, which adds up fast over long distances. If you're making a big country trip, it's worth topping up before you leave the metro area.

Choosing a cheaper brand, like Solo or Burk, over an expensive independent station could save you up to 37c per litre. On a weekly fill, that's not loose change.
