Regional WA Petrol Eases as Jerramungup and Morawa Lead the State's Unleaded Lower
A comprehensive analysis of this week's Western Australia fuel pricing data reveals a notable easing across the state's regional unleaded market, with the wheatbelt towns of Jerramungup and Morawa recording two of the largest single week movements anywhere in the country.
According to data captured on Sunday 21st June 2026 at 8:13am AWST, unleaded petrol in Jerramungup eased to a five station average of 193.0 cents per litre, down a substantial 22 cents from 215.0 cents the week prior. Neighbouring Morawa followed a similar path, with regular unleaded settling at 196.3 cents, a fall of 15.7 cents from 212.0 cents seven days earlier.
Breaking down the regional numbers
These are sizeable shifts for two towns that sit well outside the capital, and they show how quickly regional pricing can correct once a local board moves. For motorists in the wheatbelt, where the nearest alternative servo can be an hour's drive away, a 22 cent swing is the difference between a comfortable tank and a painful one.
The movement was not confined to standard unleaded. Premium grades eased in lockstep, with premium 98 at Jerramungup down 15.1 cents to 219.9 cents. That pattern points to a single supply or freight adjustment flowing through every grade on the board at once, rather than a fuel specific story.
The contrast with Perth and the wider metropolitan market is worth a mention, because pricing there tends to follow Western Australia's distinctive weekly rhythm. Unlike the eastern states, WA runs a published daily price notice system, which means tomorrow's board prices are known in advance. The metro low typically lands early in the week, with prices stepping up sharply mid week before grinding back down.

The wider WA picture
While unleaded eased in the regions, the state's diesel market told a more mixed story. Western Australia's statewide diesel average sat at 204.7 cents per litre across more than 1,200 stations, the highest of any mainland market apart from the Northern Territory. Yet metro pockets stayed genuinely competitive. Perth fringe suburbs including Forrestfield, Wanneroo and Kwinana Beach held diesel near or below 172 cents, a reminder of just how wide the spread within a single state can be.
That spread is the recurring theme of WA pricing. The gap between the cheapest metro servo and the dearest remote station ran past 230 cents this week, by far the widest band in the nation. Freight distance, single operator towns with no nearby competition and the sheer scale of the state's interior all push remote prices higher and keep them stickier on the way down.
What it means for motorists
For drivers in Jerramungup and Morawa, this week's easing is welcome relief, though regional boards can be slow to follow when the next upward move arrives. The lesson from the data is the same one that holds across the state. Location and timing remain the two levers within a motorist's control.
Those travelling between regional centres and the coast would do well to compare boards before committing to a fill, particularly given the scale of the spreads on display. A quick check of nearby suburb pricing can comfortably save eight to ten dollars on a single tank when the gap stretches past 20 cents a litre, as it did this week.
This pattern of regional volatility against a steadier metro backdrop is one Western Australian motorists know well, and it is unlikely to change while the state's geography keeps remote supply chains long and local competition thin. For motorists willing to shop around and watch the daily notice, the data clearly demonstrates that location and timing remain the two most important factors in fuel savings.
