Dairymans Plains Diesel Holds at 224 Cents While New South Wales Climbs 4 Cents Against the National Tide

A comprehensive analysis of this weekend's fuel pricing data reveals New South Wales is moving sharply against the grain. Diesel across 1,128 NSW servos has climbed 4.2 cents to a state average of 254.1 cents per litre as of 3rd May 2026 02:00pm AEST, the only mainland state to register a meaningful increase while Western Australia sheds 22 cents in the same 24 hour window.

Drilling down into the specifics, the data paints a clear picture of a state pulling in the opposite direction to almost every other Australian market. According to recent data from across all 1,128 NSW diesel stations, the cheapest pumps still sit at 219.5 cents while the most expensive remote outlets reach 375.0 cents, a 155 cent spread that ranks NSW second only to Northern Territory for intra state diesel disparity.

Dairymans Plains anchors the cheapest list

Breaking down the regional differences, the Snowy Mountains hamlet of Dairymans Plains has emerged as the most affordable diesel pocket in the state. Three servos in the area are averaging 227.2 cents per litre, with the cheapest pump posting 223.9 cents and the most expensive only 6 cents above. This is the kind of price compression that signals genuine competition rather than a single outlier dragging the average down.

For freight operators running the Hume corridor, Marulan presents the next most compelling case. Four stations in the Southern Tablelands township are averaging 238.2 cents, with the cheapest at 231.9 cents and the most expensive at 244.9 cents. The 13 cent spread is wider than Dairymans Plains but still tight by NSW standards, where the statewide range exceeds 155 cents.

Historical comparison shows Marulan has long served as a strategic refuel point between Sydney and Canberra, and the current pricing reflects that competitive pressure. Drivers heading south on the Hume Highway can save roughly 16 cents per litre by filling at Marulan rather than the NSW state average.

Sydney's western suburbs hold firm

The data tells a similar story across Sydney's western corridor. Smithfield ranks among the state's cheapest diesel suburbs at an average of 236.3 cents, with the lowest pump at 229.5 cents. Just to the south, Greenacre servos are holding at 236.9 cents on average, with a cheapest pump of 233.9 cents.

Drilling further into Sydney's fringe, Port Kembla on the Illawarra coast posts an average of 238.6 cents across three stations, with a remarkably tight 4 cent spread. Gunnedah in the New England region delivers the rare sight of zero variance: all four stations have settled at exactly 239.9 cents, suggesting the regional brands are watching each other closely.

This pattern is consistent with what industry analysts describe as suburb level price clustering. When competition is concentrated and freight differentials are similar, retailers tend to converge on a narrow band rather than risk losing volume to a neighbour two minutes away.

Why NSW is climbing while the West collapses

Market dynamics behind the divergence come down to two industry factors. First, NSW relies heavily on imported finished diesel through Port Botany, leaving local pricing exposed to shipping rate movements and refiner margin shifts that have firmed over the past fortnight. Second, Western Australia draws diesel through Kwinana refinery economics that have moved in the opposite direction, with Forrestfield and Kwinana Beach servos already pushing under 220 cents per litre.

The upshot for NSW motorists is that the easy savings sitting on the WA west coast are not coming east any time soon. Pricing trends suggest the NSW climb is structural rather than a single day spike, with the state average now sitting roughly 2 cents above Queensland and within a cent of Victoria.

What this means for fleet operators

For a Hilux running a 80 litre tank, filling at Dairymans Plains at 223.9 cents instead of the NSW average saves roughly $24 per fill. Across a weekly schedule that compounds quickly. For light commercial fleets running multiple vehicles, the gap between the cheapest NSW suburb and the state average is now larger than the entire weekly margin many small operators run on.

The data clearly demonstrates that location and timing remain the two most important factors in fuel savings. With NSW continuing to firm while WA collapses, motorists planning interstate runs would do well to top up before crossing the border east.
