Western Sydney Diesel Holds Near 240 While Orange Eases 8.5 Cents

According to pricing data collected at 2:07pm AEST on 6th Sep 2026, diesel across 1,247 monitored servos in New South Wales averages 255.2 cents per litre, level with Victoria and under Queensland on 256.3 and Western Australia on 256.9. NSW now shares the equal cheapest diesel average in the country. The state figure eased 0.7 cents on yesterday, which reads as flat. The suburb numbers underneath it are not.

Orange records the largest diesel decrease in the state

Orange is the standout mover. Its eight station sample averages 247.4 cents, down 8.5 cents from 255.9, and that is the sharpest diesel fall recorded anywhere on the Australian mainland this round outside the Western Australian wheatbelt, where Morawa shed 10.4 cents.

Orange supports orchards, mine traffic and a steady stream of freight along the Mitchell Highway, so 8.5 cents counts for something there. On a 70 litre ute tank it is close to $6 a fill, and on a light truck running 200 litres a week it approaches $17. A movement that size across eight sites means several operators have reset together rather than one outlier dragging the average down.

Wagga Wagga moves the other way

Roughly 300 kilometres to the south the direction reverses. Premium diesel across the eight station sample in Wagga Wagga averages 253.6, up 8.1 cents from 245.5. Standard diesel in neighbouring East Wagga Wagga is holding better at 242.5 across three sites, with a tight spread of just 6 cents between cheapest and dearest.

That gap matters for anyone running a modern common rail engine that does not strictly require the premium product. The roughly 11 cents now sitting between standard and premium diesel in the Riverina is wider than the national norm, and most passenger vehicles will not notice the difference.

Western Sydney is where the steady value sits

The most consistent diesel pricing in the state is not regional at all. Three western Sydney suburbs sit in the national top 40 for cheapest diesel, and all three are within a short drive of each other.

Fairfield leads the group on 240.0 cents across four servos with a spread of only 1.4 cents. Granville follows on 242.8 across three sites. Smithfield averages 243.5 across four, though its 16.4 cent spread means the cheapest site at 237.5 is worth seeking out rather than pulling into the first driveway you pass. On a 70 litre fill that spread is worth about $11.50, and both ends of it are in the same suburb.

Dense industrial corridors tend to price this way. Where truck traffic, distribution centres and competing brands sit within a few streets of each other, the spread compresses and the average falls. Fairfield's 1.4 cents is effectively a market where nobody can afford to be the dear one.

Regional NSW is not uniformly dearer

Regional diesel usually carries a clear penalty over metro, but several NSW country centres are holding their own this round. Bomaderry on the South Coast averages 242.4 across four sites with the cheapest at 233.9, a genuinely competitive figure by any measure. That is 8.5 cents between the Bomaderry average and its own cheapest pump, the same margin Orange shed across the whole town this round. Oberon also averages 242.4, while Gunnedah and Bodalla both sit on 244.6, Bodalla with almost no variation between its four servos.

The national picture

Diesel remains elevated against petrol right across the country, and the four largest mainland states are bunched inside 1.7 cents of each other on the average. The NSW range runs from 219.5 at the cheapest monitored site to 336.0 at the dearest, a spread of 116.5 cents, which is narrower than Victoria on 142.0 and considerably tighter than the Northern Territory at 231.9. Elsewhere, Hastings unleaded lifted 10.7 cents while the Barossa region in South Australia eased 13.2 cents on unleaded, so movement is running in both directions depending on where you fill up.

Our diesel prices page updates as each source reports, and the price trends tool shows how these movements have played out over recent weeks.

Location and timing remain the two levers that matter in fuel savings. In NSW this week that means the western Sydney corridor for metro drivers, and Orange for anyone travelling through the Central West.
