The capital city that pays 12c more in petrol than Sydney

The Queensland government has refused to take the lead in addressing the state's high fuel prices, saying the responsibility lies with the nation's consumer watchdog.

Premier Annastacia Palazczuk on Monday said her government had no plans on rolling out a real-time fuel pricing app or website to help motorists shop around and keep retailers accountable.

Brisbane fuel prices have soared to $1.50 per litre, which is 12 cents higher than the average prices in Sydney, the ABC reported.

The average price for unleaded fuel in Brisbane is sitting at $1.49 per litre.

"This is a national issue and the ACCC really does need to take charge here," Ms Palazczuk told reporters in Logan.

However, the RACQ said a similar scheme has already been rolled out by the NSW government, which has made it compulsory for service stations to immediately advise the public when prices go up or down.

"The Queensland government should look to what they have done in NSW," spokeswoman Renee Smith said.

"We need to empower motorists as much as possible so they can know where the best price is, and they don't have to waste time driving around looking for the cheapest fuel."

Drivers in Brisbane were paying up to 30 cents a litre more on Monday than they were a week ago.

Ms Smith said big companies like BP and Coles were often unnecessarily driving prices up, and called on consumers to instead support smaller retailers.

However, Ms Palaszczuk refused to support calls for a boycott.

"I think that's a matter for independent consumers to make that decision," she said.

"Unfortunately during specific times of the year some of these petrol companies are gouging... and I don't think that's fair on consumers."

Price-monitoring agency Fueltrac has flagged the appointment of a new fuel commissioner and the introduction of capped profit margins as another solution to the high prices.

However, Ms Smith said the RACQ was not convinced this was the best solution.

"We're not sold on that idea because if we cap prices then they may not move around as much and they might just stay high all the time," she said.
