NSW Diesel Rises 3.8% While Victoria and WA See Relief at the Pump

Australian diesel markets showed significant divergence overnight, with New South Wales experiencing a substantial 7.0 cent increase while Victoria and Western Australia motorists enjoyed modest relief. The data reveals a stark regional divide that merits closer examination.

The Numbers Tell a Clear Story

NSW diesel prices increased from 182.9 cents to 189.9 cents per litre, representing a 3.83% jump across 1,279 reporting stations. This places NSW among the more expensive diesel markets nationally, with the state average now matching Tasmania's first reported figure of 189.0 cents.

In contrast, both Victoria and Western Australia saw their averages decrease by 2.8 cents, a 1.46% reduction. Victoria's 1,312 stations now average 188.8 cents per litre, while WA's 441 stations sit at 188.6 cents. Queensland followed NSW's upward trajectory with a more moderate 3.5 cent increase to 195.7 cents, and South Australia rose 2.6 cents to 189.2 cents.

Where to Find the Best Diesel Prices

The data identifies Granville in NSW as offering the nation's cheapest diesel at 169.5 cents per litre across three reporting stations. This represents a 20.4 cent discount compared to the NSW state average, illustrating the substantial savings available to motorists willing to compare prices.

In Victoria, Wendouree stands out not only for competitive pricing at 165.2 cents minimum but also for recording the largest single day drop of 21.4 cents. The suburb's eight stations now average 175.5 cents, down from 196.9 cents previously. Similarly, Ballarat saw diesel prices decrease 20.7 cents to an average of 184.7 cents.

Western Australia's best value appears in Bassendean, where three stations offer diesel from 169.3 cents, and Byford with prices starting at 171.5 cents. Both suburbs significantly undercut the WA state average.

Price Spread Analysis Reveals Market Inefficiencies

The price spread data exposes considerable market variation within states. Victoria displays the widest spread at 140.7 cents between its cheapest and most expensive diesel, ranging from 165.2 cents to 305.9 cents. NSW shows a 102.0 cent spread, while WA maintains a tighter 75.0 cent range.

Tasmania's newly available data indicates a relatively compressed market with just a 22.1 cent spread across 41 stations, suggesting more consistent pricing in the smaller market. The Northern Territory, by comparison, shows a 189.5 cent spread, reflecting the significant cost differences between urban and remote locations.

Regional Victoria Sees Broad Based Relief

Beyond Wendouree and Ballarat, several regional Victorian centres recorded notable decreases. Bendigo diesel fell 11.1 cents to average 188.3 cents across eight stations. Mildura decreased 10.4 cents to 189.5 cents with data from 12 stations, while Traralgon dropped 11.7 cents to 186.2 cents.

This pattern suggests a coordinated market adjustment in regional Victoria, possibly reflecting wholesale cost changes or competitive repositioning following a previous price spike.

Tasmania Data Now Available

This marks the first comprehensive Tasmania diesel pricing report, with 41 stations now contributing data. The state average of 189.0 cents places it in the middle of the national range, with prices spanning from 179.9 cents to 202.0 cents. The 22.1 cent spread indicates relatively consistent pricing across the island state.

What the Data Suggests

The divergent price movements across states likely reflect different stages in the fuel price cycle, with NSW potentially entering an upward phase while Victoria and WA experience downward corrections. The 3.83% increase in NSW is statistically significant and suggests either wholesale cost pressures specific to that market or strategic pricing adjustments by major retailers.

For commercial operators and frequent drivers, the 20 to 30 cent variations between cheapest and average prices within individual suburbs present clear opportunities for cost management through strategic refuelling decisions.

Actionable Intelligence for Motorists

The current data indicates that motorists in Sydney should prioritise western suburbs like Granville, Fairfield (174.9 cents minimum), and Auburn (175.5 cents minimum) for substantial savings. Victorian drivers have extensive options in Ballarat region towns, while Perth motorists should focus on southern suburbs and regional centres like Busselton (170.2 cents minimum).

Queensland's 195.7 cent average remains among the highest on the mainland, making price comparison particularly valuable in that market. South Australia's 189.2 cent average positions it near the national midpoint.

The introduction of Tasmania pricing data provides a more complete national picture and enables better benchmarking of regional price performance. As this data stream matures, it will reveal whether Tasmania follows mainland price cycles or maintains independent dynamics.
