NRMA spokeswoman Rebecca Page said prices have been stable in regional areas.

"The message from the NRMA today is that if you really don't want to be paying for the most expensive fuel in your area, you have to do research.

"You have to have a look at the live petrol prices, which are available through the NRMA app."
