Queenslanders will be able to shop around more easily for cheaper petrol prices from Monday, with a two-year fuel price-monitoring trial due to begin.

From noon on Monday, more than 1000 service stations in Queensland will be required to lodge their fuel prices via an online portal within half an hour of their changing at the browser.

This data will be collated and provided to companies’ hosting apps, such as MotorMouth, GasBuddy and the RACQ, as well as any innovators interested in entering the market.

Energy Minister Anthony Lynham said that, over the next few weeks, motorists would begin seeing up-to-date prices appearing on apps and websites.

About 1300 of Queensland’s 1446 service stations had signed up on Friday to share their prices, with some operators still working to get systems in place.

Prices from some of Queensland’s servos currently appear on various apps and websites, but they can be hours or even days out of date.

Under the Queensland government’s two-year trial, retailers will face fines of up to $13,000 for not reporting price changes within 30 minutes.

However, retailers will have three months’ grace to get their processes right, with fines to be handed out by Easter 2019 if they do not update fuel prices accurately and on time.

Dr Lynham said his department would continue to follow up with retailers to get them on board as soon as possible.

RACQ public policy head Rebecca Michael said the initiative would help put the power back into the hands of drivers and allow them to reward retailers that offered the best deal.

“Our members ask for fuel price information and advice more than any other subject and we know Queensland motorists pay some of the highest petrol prices in the country,” Dr Michael said.

“That’s why we’ve lobbied so hard to get them access to the latest fuel prices at all retailers — not just those who choose to give us their data.

“We know lower fuel prices start with increased competition and this change will offer greater transparency for motorists.”

The LNP previously called for real-time monitoring of fuel prices and had pledged to introduce the measure if it won the 2020 state election.

In central Brisbane, a fair price for unleaded fuel was 134.6 cents on Sunday, with the cost trending upwards, according to the RACQ.
