You no longer have to drive around guessing. In several states, petrol stations are required to report their prices in real time, and that data feeds live maps and apps. In New South Wales it comes from the FuelCheck scheme, and in Western Australia from FuelWatch. Both let you see current prices at stations near you before you leave home.
EnergySorted has a live cheapest-fuel-near-you map for NSW and WA built on this data, so you can find the lowest price for your fuel type close to you without hopping between apps. Because prices can swing by 30 to 50 cents a litre across a single city on the same day, checking before you fill is one of the highest-value minutes you can spend.
How to actually find the cheapest fuel
Check a live price map or app for your area and filter to your fuel type: E10, unleaded 91, 95, 98 or diesel.
Sort by price, but weigh in the detour: a station 15 cents cheaper across town can cost more in fuel and time than it saves on a small fill.
Note the day in the price cycle if your city has one. Filling near the bottom of the cycle beats filling at the top by a wide margin, as our guide to petrol price cycles explains.
Fill up properly when prices are low rather than topping up small amounts at whatever the price happens to be.
Combine the cheap fill with a trip you were making anyway so the detour costs nothing.
Watch the traps
The lowest advertised price is not always the best deal once you factor in distance. A useful rule of thumb: a saving is only real if the extra driving to reach it costs less than the difference. For a 50-litre fill, even a few cents a litre adds up, but for a quick top-up the maths flips.
Loyalty and shopping-docket discounts of a few cents a litre are worth using, but do not let a small locked-in discount keep you at a station that is 20 cents dearer than one down the road. The base price matters far more than the discount stacked on top.
Habits that beat any single cheap fill
Finding the cheapest station helps, but how you drive and maintain the car compounds over the year. Correct tyre pressure, a lighter load, smooth acceleration and not idling all improve fuel economy measurably. Using the right fuel for your engine (rather than needlessly buying premium) also keeps costs down without any loss.
Together, checking live prices before you fill and driving efficiently will save more than chasing the occasional bargain across town. Using the right grade for your engine matters too, so if you are unsure whether you need premium, our guide to E10 vs unleaded 91 vs diesel sorts it out. Set the habit of a quick price check, and let the map do the searching for you.
Frequently asked questions
How can I see live petrol prices near me?
In NSW and WA, stations report prices in real time through FuelCheck and FuelWatch. EnergySorted's live cheapest-fuel-near-you map uses this data so you can see current prices by fuel type close to you before heading out.
Is it worth driving further for cheaper petrol?
Only if the saving beats the cost of the detour. For a large fill, a few cents a litre is worth a short drive; for a small top-up it often is not. Weigh the per-litre saving against the extra fuel and time to get there.
Do loyalty and docket discounts actually help?
A few cents a litre off is worth using, but the base price matters far more. Do not let a small discount keep you at a station that is much dearer than a nearby one with no discount.
Which states have live fuel price data?
New South Wales (FuelCheck) and Western Australia (FuelWatch) have mandatory real-time price reporting, which is what EnergySorted's live map covers. Other states have varying arrangements and less complete real-time data.
What saves more: cheap fuel or efficient driving?
Over a year, efficient driving and maintenance usually save more than chasing bargains. Correct tyre pressure, smooth driving and using the right fuel for your engine compound every tank, while a cheap fill is a one-off.
What is a petrol price cycle and how do I use it?
It is a repeating pattern where prices jump then slowly fall before jumping again. Filling near the bottom of the cycle rather than the top saves a lot on a full tank.
Which fuel type should I actually be buying?
Use the minimum grade your manufacturer specifies, printed inside the fuel flap or in the manual. Paying for higher octane your engine cannot use is wasted money.
How do I find the cheapest petrol in Sydney?
NSW runs the FuelCheck real-time scheme, so a live map shows every station's current price. See our Sydney-specific tips in how to find the cheapest petrol in Sydney.
How do I find the cheapest petrol in Perth?
WA's FuelWatch publishes tomorrow's prices in advance and holds them fixed, so you can plan a cheap fill a day ahead. Our Perth fuel guide explains the 24-hour rule and weekly pattern.
How much can petrol prices vary across a city in one day?
A lot. Same-day differences of 30 to 50 cents a litre between stations are common in the big capitals, driven by where the city sits in its price cycle and local competition. That is why a quick check before filling is worth it.
Is EnergySorted's fuel map free to use?
Yes. The live cheapest-fuel-near-you map is free and covers NSW and WA. Filter to your fuel type and it shows the lowest prices around you, no account required.
