Revesby Unleaded Falls 14 Cents to 195 Cents While NSW Diesel Average Drops 23 Cents Across a Single Cycle
A comprehensive analysis of fresh pricing data from across New South Wales reveals a substantial reset underway, with Revesby leading the state's unleaded fall and diesel averages falling more than 23 cents a litre at the same time. The figures, drawn from 1,129 monitoring points across the state as of 19th Apr 2026 2:00pm AEST, paint a clear picture of a broad softening that motorists should be aware of before filling up this weekend.
The Revesby Story
Drilling down into the specifics, six servos in Revesby have collectively pushed the suburb's unleaded average from 209.9 cents to 195.6 cents, a fall of 14.3 cents. That puts the southwestern Sydney suburb among the most competitive metro pockets in NSW for standard petrol this week. For a 55 litre tank, that shift alone translates to roughly $7.85 in savings per refill compared with what motorists paid a few days ago.
The story does not end there. Premium diesel at seven Revesby sites has also dropped 11.4 cents, from 309.9 to 298.5 cents, suggesting the discount is not confined to a single fuel grade. That kind of synchronised move across multiple fuel types usually indicates a wholesale price pass through rather than a single servo undercutting the market, which is useful context for motorists trying to work out whether the drop will hold.
Breaking Down the NSW Diesel Numbers
The headline statewide figure is the diesel movement. Across 1,129 stations, the NSW diesel average has fallen from 327.6 cents to 304.0 cents, a decline of 23.6 cents or 7.2 percent. Breaking down the regional differences, the minimum price recorded anywhere in the state sits at 229.9 cents, while the most expensive reading remains 375.0 cents, giving the state a spread of 145.1 cents between its cheapest and dearest bowsers.
Historical comparison across the eastern seaboard is instructive here. NSW diesel at 304.0 cents now sits just above Queensland at 303.8 cents and only modestly above Victoria at 301.8 cents. This pattern is consistent with wholesale diesel movements flowing through the three largest refining markets at roughly the same pace, although NSW retailers took slightly longer to pass through the cut than their southern counterparts.
Where NSW Diesel Buyers Should Look
For diesel drivers in particular, analysis of the cheapest metro suburb averages shows Smithfield leading the pack with a three station average of 275.6 cents and a low of 267.5 cents. Fairfield is close behind at 280.6 cents average across four servos, although the 47.4 cent spread in that suburb means motorists really do need to check prices before pulling in. Greenacre sits at 279.9 cents on average across three monitored sites.
The coastal and regional picture is equally competitive. Port Kembla in the Illawarra has logged a cheapest diesel price of 262.9 cents, the lowest single reading among the competitive clusters reviewed here. Further south, Goulburn offers a seven station average of 287.8 cents with a tight 13.0 cent spread, making it a reliable refuel stop for motorists heading between Sydney and Canberra.
Industry Factors and What Comes Next
The data paints a clear picture of a discount cycle trough across metropolitan NSW, with Revesby and the southwestern corridor capturing the sharpest falls. Historical data suggests these troughs typically last between five and ten days before retailers begin nudging prices back up, so the window for cheap fills is likely narrow.
For motorists willing to shop around, the data clearly demonstrates that location and timing remain the two most important factors in fuel savings. Cross referencing the Revesby unleaded average against Sydney's broader median, filling up in the southwest rather than an inner suburb currently saves roughly 10 to 15 cents a litre, or more than $8 on a family sedan tank. Checking live prices on the interactive fuel map before committing to a fill remains the single highest impact step a Sydney driver can take this week.
