The Queensland premier has called on the consumer watchdog to intervene after it was revealed Brisbane drivers were paying $50 million a year more than interstate counterparts.
It comes as the Australian Competition and Consumer Commission revealed on Monday that Brisbane drivers were paying 3.3 cents a litre more than motorists in Sydney, Melbourne, Adelaide and Perth.
Annastacia Palaszczuk challenged the ACCC to establish a national fuel price disclosure system to better inform motorists of real-time prices but did not provide details about how it would work.
"It's a bit unfair that Queensland tends to pay higher prices than the rest of Australia and frankly it's not good enough," she told reporters.
"We've been speaking to the federal authorities about this and it's about time they listen.

"I would like to see the ACCC implement a real-time disclosure right across the country."
ACCC chairman Rod Sims said the findings confirmed Brisbane drivers were paying too much for petrol and some fuel retailers were "enjoying high profit margins at their expense".
Brisbane petrol retailers' net profits were 55 per cent higher compared with their interstate counterparts during 2015/16 financial year.
Energy Minister Mark Bailey lashed retailers over the findings.
"This is quite literally highway robbery and clearly unacceptable," he said.
RACQ spokeswoman Renee Smith called on the Queensland government to step in with fuel price transparency laws.
Mr Bailey said the Palaszczuk government acted in August by instigating a price campaign banning misleading discounted prices on fuel price boards.
The campaign will come into effect from January.
