A BASE jumper who competes in the sport internationally has faced court after he leapt off Brisbane's iconic Story Bridge.

Richard James Convery, 25, of Hope Island pleaded guilty in the Brisbane Magistrates Court on Wednesday to unregulated high risk activities on the bridge on September 20.

Police told the court it was 10.20pm when Brisbane City Council asked them to go to the bridge.

When officers arrived, they spotted Convery driving a black 4WD with water dripping off the back of it.

Three other people were found in the car, before police found a wet helmet and parachute in the tray of the vehicle.

The court heard Convery readily admitted he had been base jumping, and that he had previously done 250 jumps all over the world.

He was taken to the watchhouse where he was charged.

Defence counsel Andrew Preston said his client had checked for traffic and pedestrians before completing the jump, but added he was remorseful and had no intention of coming before the court again.

He said while Convery was an experienced base jumper who competes overseas, he regretted his actions on this night.

Magistrate Alan Taylor told the mine worker the offence was serious, and had safety implications not only for himself but for members of the public.

He sentenced Convery to a 12-month good behaviour bond and did not record a conviction against him.
