Fuel Map is a crowd-sourced database of petrol stations and fuel prices from all across Australia. All station information is added and edit by users like yourself. You can also add current fuel prices which are then shared with other users of Fuel Map.
Fuel Map also shows real-time fuel prices for WA, NSW, and QLD sourced from government resources.
Stations in WA show prices for both today and tomorrow! (Tomorrow's prices are available after 2:30pm)
