Bathurst Diesel Holds Below 220 Cents While NSW Climbs 14 Cents Overnight and Singleton Pricing Tightens to Just 1 Cent
This morning's data uncovers some interesting patterns across New South Wales that deserve closer scrutiny. While the state average diesel price climbed 14.2 cents overnight to sit at 265.4 cents per litre, a closer look at regional pricing reveals motorists in Bathurst can still find diesel at 218.9 cents. That is a 46.5 cent gap between the cheapest pump in regional NSW and the state average, on the same day the state lifted prices broadly.
The morning data, captured at 8:06am AEST on 27th Apr 2026, shows NSW now sits as the second most expensive mainland state for diesel behind South Australia at 270.4 cents and Queensland at 267.3 cents. Compare that against Western Australia at 260.4 cents and Victoria at 261.4 cents, both of which moved in the opposite direction overnight, and the picture starts raising some interesting questions about how the eastern states are pricing fuel right now.
The Bathurst anomaly worth investigating
Bathurst is a town of around 38,000 people sitting roughly three hours west of Sydney, and it should not be Australia's hidden diesel bargain. Yet across three monitored servos in Bathurst, the cheapest pump is offering diesel at 218.9 cents while the most expensive sits at 275.9 cents. That is a 57 cent spread inside one regional town, suggesting at least one operator has decided to price aggressively below local norms.
This raises questions about why this kind of competitive pricing isn't reaching the metro market. Sydney drivers heading west for the long weekend can effectively top up cheaper than they could in their own suburb. Three hours of driving for a saving of 30 to 40 cents per litre. On a 70 litre tank, that is a real consumer dividend that flies under the radar of the major price comparison headlines.
Singleton's remarkable 1 cent spread
Digging deeper into the numbers, the Hunter Valley town of Singleton presents an entirely different story. Across four monitored stations, the cheapest diesel sits at 243.5 cents and the most expensive at 244.9 cents. A spread of just 1.4 cents per litre. For context, most NSW suburbs are showing diesel spreads of 15 to 30 cents between the cheapest and most expensive pumps. Singleton's pricing is so tight it is statistically unusual.
Now, tight pricing is not automatically suspicious. It can reflect genuine competitive equilibrium where every operator has matched the local market floor. But when a regional town shows a spread that narrow while neighbouring areas are spreading 20 cents and more, it is worth noting. Motorists in Singleton are not getting the worst of it, but they are also not getting the best of it either.
Similar tight clustering shows up at Batemans Bay on the south coast, where three monitored stations spread just 1 cent across 243.9 to 244.9 cents. Two regional NSW towns showing the same locked pricing behaviour on the same morning is a pattern that consumer advocates should keep an eye on.
Where the regional bargains are hiding
A closer look at the cheapest cities table reveals a cluster of regional NSW towns offering meaningful savings against the metro average. Marulan sits at 229.9 cents cheapest, Forbes at 237.9 cents, Coolac at 239.5 cents, and Goulburn at 241.9 cents. The Greenacre and Smithfield corridor in western Sydney remains the metro outlier, holding diesel at 235.7 and 234.5 cents respectively while the broader Sydney basin pushes higher.
Motorists planning longer trips should be aware that the NSW average masks a remarkable range. The cheapest diesel in NSW today sits at 218.5 cents and the most expensive at 375.0 cents. A 156.5 cent spread across the state. That is the widest spread of any mainland state and a clear sign that price transparency tools matter more than ever for NSW consumers.
The takeaway for NSW motorists
The variation between regions is striking. NSW lifted its diesel average 14.2 cents in 24 hours, but the cheapest pumps in Bathurst, Marulan and Western Sydney barely moved. That tells us the price rise is not universal. Some operators are absorbing wholesale movement and some are passing it through immediately, often without a clear pattern.
Motorists should be aware that paying anywhere close to the 265 cent state average in NSW today means missing out on substantial savings available within an hour's drive. The Petrolmate map captures these movements every few hours, and the regional bargains are not subtle. Armed with this information, NSW drivers can make informed decisions and avoid paying more than necessary for what should be a transparent commodity.
