Queensland Diesel Holds Above 221 Cents as NSW Prices Surge 21 Cents Overnight

Looking at the latest data from across Australia, one statistic stands out above the rest: NSW diesel prices jumped 21.5 cents overnight, an 11.15 percent increase that pushed the state average to 214.3 cents per litre. That is the single largest overnight diesel movement recorded this week across any state, and it has dramatically reshaped the national pricing landscape.

Meanwhile, Queensland motorists continue paying the highest mainland diesel prices in the country at 221.7 cents per litre, a figure that has remained stubbornly stable while other states swing wildly around it.

Queensland's Persistent Premium

The data indicates Queensland diesel has barely moved, recording zero change from the previous day. At 221.7 cents per litre across 93 reporting stations, the state sits a substantial 17.1 cents above Victoria and 16.7 cents above Western Australia.

What makes this notable is the consistency. While other states experience dramatic overnight swings, Queensland pricing has remained anchored above 220 cents. The state's cheapest diesel sits at 191.5 cents and the most expensive at 272.9 cents, giving a spread of 81.4 cents. That spread suggests motorists in the right Brisbane suburbs could save substantially compared to regional areas, but even the floor price of 191.5 cents is higher than the state averages in both Victoria and Western Australia.

NSW Closes the Gap

The overnight surge in New South Wales has narrowed the gap between Australia's two most populous eastern states. NSW diesel now sits at 214.3 cents, just 7.4 cents behind Queensland. A week ago, that gap was closer to 30 cents.

Across 1,040 NSW stations, the price spread tells an interesting story. The cheapest diesel available sits at 173.7 cents in regional areas like Barham, which is recording an average of 195.3 cents with individual servos as low as 173.7 cents. Coolah in central western NSW offers diesel from 183.9 cents. Yet the most expensive NSW station is charging 317.9 cents, a spread of 144.2 cents that ranks second only to the Northern Territory.

This 21.5 cent jump represents the kind of wholesale cost pass through that typically hits metro stations first before filtering into regional areas over the following days.

The National Picture

A closer analysis reveals three distinct pricing tiers have emerged across the country.

Tier 1: The expensive states (above 210 cents)

Tier 2: Below the $2.10 mark

The gap between the cheapest state average (Victoria at 204.6 cents) and the most expensive (Northern Territory at 245.8 cents) is a notable 41.2 cents per litre. On a 70 litre tank, that represents a difference of $28.84.

Where to Find Cheaper Diesel

For motorists hunting value, the data points to several suburbs worth checking.

In Victoria, regional towns continue to undercut metro pricing. Timboon in the Western District is averaging 183.8 cents with servos as low as 174.9 cents. Bayswater North in Melbourne's eastern suburbs sits at 179.9 cents at its cheapest, while Casterton near the South Australian border has diesel from 169.9 cents.

In Western Australia, Roleystone south of Perth is recording diesel from 172.9 cents. Geraldton on the mid west coast offers 179.9 cents across seven stations, and Wanneroo in Perth's northern corridor has prices starting from 183.5 cents.

The Northern Territory presents a fascinating case. Despite its 245.8 cent average, the minimum recorded price is just 147.3 cents, creating the widest spread of any state at 251.7 cents. Katherine South averages 196.6 cents, well below the territory average.

What This Means for Motorists

The numbers are clear: the national diesel market is splitting into two camps. Victoria and Western Australia are holding below 205 cents, while six other states and territories sit above 212 cents. Queensland's persistent premium and the sudden NSW surge suggest eastern seaboard motorists should expect elevated pricing through the coming week.

For those with flexibility on where they fill up, the suburb level variations remain substantial. A 10 minute detour to a cheaper servo could save $10 to $15 per tank in most capital cities. The data consistently shows that motorists who compare prices before filling up save the most.
