14th Nov 2025 11:41am AEDT | By Jenny Nguyen
Western Australian motorists shopping for diesel today face one of the widest price spreads in the country, with a 71 cent difference between the cheapest and most expensive bowsers across the state's 412 monitored service stations.
While the state average sits at 188.3 cents per litre, a modest 0.5 cent decrease from yesterday, the real story lies in the remarkable variation between suburbs, with some communities enjoying prices below 170 cents while others pay well over 230 cents per litre.
Bassendean Leads Metro Savings
Metro Perth motorists looking to fill up should head to Bassendean, where diesel is available from 169.3 cents per litre across three service stations. The suburb maintains a tight price range with an 8.6 cent spread, averaging 174.0 cents per litre, making it the most affordable option for diesel in the metropolitan area.
Nearby Byford offers similarly competitive pricing at 171.5 cents for the cheapest diesel, while Kwinana Beach rounds out the top metro bargains at 171.3 cents per litre. These southern suburbs consistently deliver value for motorists willing to plan their refuelling stops.
Regional Price Variations Tell Different Stories
Regional Western Australia presents a more complex picture. Busselton maintains reasonable diesel prices starting from 170.2 cents per litre across its six service stations, though the spread climbs to 15.7 cents, reflecting the mix of competitive and premium priced outlets in the tourism focused area.
Further south, Albany motorists benefit from relatively stable pricing, with six stations offering diesel between 178.5 and 184.9 cents per litre. The regional hub's 6.4 cent spread suggests healthy competition among local retailers.
Remote Communities Face Premium Pricing
The data reveals substantial price premiums in remote mining and pastoral communities. Derby motorists are paying an average of 232.8 cents per litre, with prices ranging from 230.9 to 233.9 cents across three stations. Fitzroy Crossing faces even higher costs, with diesel averaging 233.6 cents and reaching as high as 238.9 cents per litre.
Broome and Newman, both significant regional centres, are experiencing diesel prices above 220 cents per litre. Broome's five service stations average 223.7 cents, while Newman's four outlets cluster around 220.6 cents per litre.
These remote pricing levels reflect the genuine logistical challenges of fuel distribution across Western Australia's vast distances, though the tight spreads within these communities suggest pricing is largely driven by transport costs rather than local competition dynamics.
Industrial Areas Show Mixed Results
Industrial and commercial hubs around Perth display interesting pricing patterns. Malaga, known for its industrial estates, shows one of the widest metro spreads at 35.6 cents, with diesel ranging from 170.3 to 205.9 cents per litre. This variation likely reflects the mix of commercial fuel outlets and standard service stations in the area.
Welshpool and Forrestfield, both major freight and logistics centres, maintain more moderate pricing at 175.7 and 172.9 cents respectively for their cheapest diesel, offering good value for commercial operators.
Recent Price Movements
The data shows some notable recent shifts across different fuel types. Geraldton experienced a 4.0 cent increase in biodiesel 20 pricing, while Maddington saw unleaded petrol rise by 3.8 cents to 175.4 cents per litre. However, Maddington motorists found some relief with biodiesel 20 dropping 2.3 cents.
Mandurah presents a mixed picture, with biodiesel 20 up 2.4 cents but premium unleaded 98 down 2.4 cents, suggesting different competitive dynamics across fuel grades.
What This Means for Motorists
For Western Australian drivers, particularly those with diesel vehicles, today's market offers clear savings opportunities for those willing to shop around within metro Perth. The 71 cent statewide spread demonstrates the value of price comparison, with tools like Petrolmate helping motorists identify the best value options in their area.
Metro drivers in Perth's northern and southern suburbs are seeing the best value, while those in remote communities continue to face pricing reflective of Western Australia's unique geography and distribution challenges. Regional centres like Albany and Geraldton sit in the middle ground, offering reasonable prices supported by local competition.
As always, motorists should consider the total cost including travel distance when choosing where to refuel, though for regular routes through areas like Bassendean, Byford or Kwinana Beach, the savings can be substantial over time.
