How to Save Money on Fuel on an Australian Road Trip

Oct 22, 2026 · Australian Backpackers

Fuel is one of the biggest costs on an Australian road trip, but a few smart habits can help it go further. These tips work whether you're driving a campervan, a motorhome or a hire car.

Here are simple ways to cut your fuel bill without changing your trip.

Use a fuel price app

Apps and websites show current prices in your area, so you can find the cheapest station nearby. Some states publish official price information too.

Open coastal road

Fill up in towns and cities

Fuel is usually more expensive in remote areas. Fill up in larger towns when you can, but never let the tank run low before a remote stretch.

Drive smoothly

  • Stay at a steady speed, ideally around 90–100 km/h on open roads
  • Brake and accelerate gently
  • Avoid unnecessary idling
  • Use cruise control on long, flat highways

Pack light

  • Only carry what you need
  • Keep tyres at the recommended pressure
  • Avoid driving with a lot of extra weight or items on the roof

Check the fuel type

Always check whether your campervan takes petrol or diesel before filling. Using the wrong fuel can be very expensive to fix.

Look for discounts

Supermarket and loyalty programmes sometimes offer fuel discounts. Check what’s available before you fill up.
