Sydney Unleaded Turns Higher as Bexley Jumps 17 Cents While NSW Diesel Quietly Eases

A comprehensive analysis of this weekend's fuel pricing data reveals two very different stories playing out across New South Wales. Sydney's unleaded cycle has turned upward, with Bexley recording one of the sharpest increases in the country, while diesel across the state has quietly drifted lower. The fuel you buy and the day you buy it matter more than usual this week.

The Bexley signal

According to recent data captured on the morning of 5th Jul 2026, average unleaded prices in Bexley, in Sydney's south, climbed from 147.9 cents to 165.0 cents per litre across the suburb's five monitored stations. That is a 17.1 cent jump in a single reading, among the largest unleaded movements recorded anywhere in Australia over the period.

This is what the restoration phase of Sydney's petrol price cycle looks like. Retailers reset their boards sharply higher after several weeks of gradual discounting, and historical data suggests these resets arrive every four to five weeks in Sydney. They rarely stay contained to one suburb for long. When a pocket like Bexley moves 17 cents overnight, surrounding suburbs usually follow within days.

The practical takeaway is straightforward. If your local servo has not yet lifted its board, filling up now rather than midweek could save a full tank buyer somewhere in the order of ten dollars. Our best time to fill up guide tracks where each capital sits in its cycle, and the live unleaded petrol prices page shows which suburbs are still holding at cycle low levels.

Diesel tells the opposite story

While unleaded swings, NSW diesel eased. The statewide average slipped 4.1 cents to 192.8 cents per litre across 1,359 monitored stations, down from 196.9 cents a day earlier. That leaves NSW with the second cheapest diesel average on the mainland, behind only Victoria at 189.7 cents. Queensland moved the other way, adding 6.5 cents to reach 193.7, while Western Australia recorded a substantial 15.8 cent decrease to 201.5 cents after last week's sharp rise.

The divergence is not unusual. Diesel does not follow the retail discounting cycle that shapes unleaded pricing in the capitals. It tracks wholesale and international movements more directly, which is why it can ease at the very moment unleaded resets higher.

Where NSW diesel is cheapest right now

Drilling down into the specifics, the cheapest diesel in the state is found well outside Sydney. Tomingley, on the Newell Highway south of Dubbo, offers diesel from 164.5 cents, while East Wagga Wagga averages 165.5 cents across three stations with no variation between them, a full 27 cents below the statewide average.

Closer to the coast, Kempsey averages 174.0 cents and Blayney in the Central West sits at 174.9 cents. In the Sydney basin itself, Fairfield is the standout at an average of 179.0 cents with only five cents separating its dearest and cheapest stations, and neighbouring Granville is tighter still at 179.8 cents with a spread of just one cent. South of the city, Port Kembla averages 177.7 cents, the cheapest diesel pocket in the greater Illawarra.

The data paints a clear picture of how much geography matters. The gap between the cheapest diesel in the state at 157.9 cents and the statewide average of 192.8 cents is nearly 35 cents per litre, worth around 24 dollars on a 70 litre ute or four wheel drive tank. The live diesel prices page maps those pockets in real time.

What to watch this week

Two questions will define the week ahead for NSW motorists. First, how quickly resets like Bexley's spread across the rest of Sydney. If the cycle follows its historical script, most of the metro area will be 15 to 20 cents dearer by next weekend. Second, whether diesel's gentle slide continues. With Queensland firming and Western Australia correcting sharply, the east coast wholesale picture remains mixed, and our price trends page tracks both movements daily.

For motorists willing to shop around, the data clearly demonstrates that location and timing remain the two most important factors in fuel savings. Unleaded buyers in Sydney should move early this week, while diesel buyers have the rare luxury of being able to wait.
