Energy Minister Anthony Lynham said Queensland software company Informed Sources was selected to develop a system to collect and distribute petrol prices to fuel price app and web developers, as part of a two-year trial beginning in December.

"With fuel prices hitting a four-year high in the past couple of weeks, our fuel price reporting trial is on schedule to put informed buying power into motorists' hands before Christmas," he said.
