Motorists in Perth and Mandurah are advised to refuel today as petrol prices are set to increase significantly tomorrow. From 06:00 on 17 December 2025, the average price for regular unleaded petrol (ULP) in Perth will rise by 22 cents per litre to 188.3 cents per litre. With various retailers, including 7-Eleven, BP, and Caltex, raising their prices to as high as 209.9 cents per litre, consumers are encouraged to fill up before the hike takes effect.
According to the latest report from FuelWatch, this price increase means motorists may have to wait approximately a week before petrol prices reach their lowest point in the current price cycle again. The upcoming rise highlights the importance of timely refueling for those who have not yet filled their tanks.
Despite the overall increase in petrol prices, there are still opportunities for savings. Currently, there are 33 fuel stations across the Perth area offering ULP for less than 160 cents per litre. Motorists can save significantly by choosing to purchase petrol from these lower-priced sites. For instance, opting for the cheapest price over the highest could result in savings of up to $35 on a 60-litre tank, illustrating the substantial impact of price differences.
