ACT Fuel Prices – Week of 25 May 2026

Diesel Led the Falls: ACT Fuel Price Movements This Week

That diesel drop didn't happen overnight. Daily data shows prices easing steadily from 255c on Monday 25 May all the way down to 226.1c by Sunday 31 May, with the steepest slide coming between Thursday and Friday when prices tumbled from 252.5c to 237.6c in a single day. That's an unusually sharp mid-week correction, and it pulled the weekly average down significantly.

Unleaded U91 and P95 were far more stable, each edging down just 0.4c for the week. U91 drifted gradually from 184.6c on Monday to a low of 182.8c on Saturday, before ticking up a fraction to 182.9c on Sunday. The pattern is calm and consistent, no dramatic swings.

How Much You Can Save by Shopping Around for ACT Petrol Prices

Here's where it gets interesting. While the metro U91 weekly average sits at 183.9c/L, the actual spread between stations is enormous. The cheapest metro station recorded 172.9c/L and the priciest hit 199.9c/L, meaning a gap of 27c per litre depending on where you pull in. On a 50-litre fill that's a difference of $13.50, which is real money.

Brand averages tell a similar story. Metro Fuel averaged just 180.6c across eight stations, and United came in at 182.5c across three. At the other end, 7-Eleven averaged 185.7c across thirteen stations and Ampol Foodary sat at 184.9c across ten. That's more than a 5c gap between the cheapest and priciest brands, so where you choose to fill up genuinely matters.

Last Week's Cheapest Day to Fill Up in Canberra

Last Saturday, 30 May, was the cheapest day of the week to fill up, with metro U91 dropping to 182.8c/L. If you happened to top up over the weekend, you were ahead of those who filled up earlier in the week when prices were hovering closer to 184.6c.

ACT Metro Petrol Price Forecast: Early June 2026

The near-term outlook for metro U91 looks gently encouraging. Forecasts point to 182c on Monday 1 June, dipping to 180.9c on Tuesday and 180.1c by Wednesday, compared to the current metro average of 183.9c/L. Confidence sits between 65% and 78%, so treat this as a guide rather than a guarantee, but the direction is clearly downward.

For some national context, ACT metro U91 at 183.9c sits 3c above the national metro average of 180.9c/L this week.

How to Save on Fuel in the ACT Right Now

The forecast suggests prices may ease a few cents over the first days of June, so if you're not running on empty, holding off until mid-week could save you around 3-4c per litre compared to filling up today. Wherever you do fill up, the brand and station choice matters far more than timing alone given that 27c spread across metro stations. Sticking to lower-average brands like Metro Fuel or United over the pricier chains could save a regular driver several dollars every single week.
