Sydney petrol prices by suburb in April 2026 reveal a 105-cent gap between the cheapest and most expensive station in the city — meaning where you fill up matters more right now than at any point in years.
Unleaded petrol in Sydney currently ranges from 191.5 cents to 296.9 cents per litre, with a city-wide average of 218.6 cents per litre as of 16 April 2026. On a standard 50-litre tank, choosing the cheapest station over the most expensive saves $52.70.
That gap has everything to do with the Middle East conflict, the Geelong refinery fire damaging domestic fuel output, and a weekly price cycle that is currently working against you — but only if you don’t know when and where to fill up.

The divergence between unleaded and diesel is the most important number in this table. Sydney’s diesel price rose 9.1 cents per litre in a single week — and the global Gasoil benchmark that drives it remains highly volatile. Every business running trucks, vans or heavy equipment in Sydney is absorbing that increase right now.
The Best Time to Fill Up This Weekend
Today is Friday. That is important for the price cycle.
In NSW, petrol prices typically peak on Thursdays and are lowest on Mondays or Tuesdays. Thursday’s peak has just passed. Prices will generally drift lower through the weekend and into early next week — making Saturday evening through Tuesday the best window to fill up.
E10 is currently 1.6 cents per litre cheaper than regular unleaded — saving approximately 80 cents on a 50-litre tank for compatible vehicles. If your car runs on E10, use it.
Why South West Sydney Is Always Cheapest
It’s not luck — it’s economics. Western and south-western suburbs have:
- Higher station density — more competition per square kilometre forces prices down
- Lower land costs — servo operators pay less in rent, passing savings to the pump
- Higher volume — more cars = more competitive pricing to win business
Earlwood currently has the cheapest average unleaded price in Sydney at 196.9 cents per litre across four stations — compared to 203.9 cents in Casula and significantly higher in eastern and northern suburbs.
Eastern Suburbs and North Shore prices sit 20–50 cents higher per litre than South West Sydney — for the exact same fuel, from the same wholesale source.
The Geelong Fire Impact on Sydney Prices
The Viva Energy Geelong refinery — which supplies approximately 10 per cent of national fuel — is running at reduced production rates following the fire on 15 April, with the company planning to replace lost output through its import program.
NSW sources fuel through terminals in Port Botany and Newcastle — not directly from Geelong. But import replacement takes time, and global benchmark prices are already elevated. Any sustained supply tightening will put further upward pressure on Sydney wholesale prices, feeding through to the bowser within one to two weeks.
