Reducing the cost of petrol and the lack of transparency around price signage will be the main topics discussed at the Fuel Price Summit in Brisbane today.

The Queensland Government will host various industry groups as well as the Australian Competition and Consumer Commission (ACCC) at the summit at Parliament House.

Paul Turner, RACQ's general manager of external relations, said the current fuel price drop had come at an ironic time.

"The summit is not about this week but about the long term," he said.

"What the statistics have shown us is that Brisbane is more expensive than Sydney, Melbourne and Adelaide.

"There are areas of Queensland that are way too expensive when it comes to what we pay at the bowser."

Mr Turner said the key indicator of lower oil prices was not trickling back to customers in the Sunshine State.

"Margins themselves are often more affected by local competition, right down to the street and the suburb," he told 612 ABC Brisbane's Steve Austin.

"If you have good competition, then you get good prices, but if you don't, you have higher margins."

Call for fairer fuel price signs in south-east

Mr Turner said the main issue he wanted the summit to tackle was fuel price signs and supposed discounts.

"The price boards in Queensland are deceptive and they are misleading motorists as to what price they get at the bowser," he said.

"Many times we think we're eligible for the discount, but after we get there we're told we're not and you just fill up anyway.

"They rely on that, as many people pull in for the discount and then aren't eligible for it."

Mr Turner said Queensland's fuel prices had always been some of the most expensive in the country.

"We haven't seen the competition in Brisbane that we would like to see," he said.

"We've generally paid two to three cents more on average than in Sydney or Melbourne.

"Last month it was six to eight cents a litre more, so we tend to go down slower and up faster in our price cycle in the south-east.

"The basic fact is we need better competition by motorists supporting those servos that are cheaper."
