Hunter-based director Kyle Loades said drivers should not put up with price gouging on public holiday weekends and should instead dob in operators who try to charge more than yesterday's average price of $1.28.

"There's no justifiable reason for it to go up," Mr Loades said.

"Based on the crude oil prices and the strength of the Aussie dollar there is no justifiable external reason for consumers to be hit with increased prices.

"It's to do with local markets and oil companies and operators taking advantage of the long weekend."

Mr Loades said motorists could vent their fury online at www.roadtube.com.au and the NRMA would forward their messages on to the competition watchdog.

"Major oil companies have been making millions of dollars of profits off the back of Hunter motorists paying too much," he said.

"We want to take those complaints and observations to the [Australian Competition and Consumer Commission] and the fuel commissioner and actually get something done about it.

"We are sick of being taken advantage of, but we need to build some momentum first and for motorists to dob in operators who overcharge."

The Service Stations Association spokesman Ron Bowden said fuel prices were expected to come down over the next few days because of the weekly price cycle.
