The 21-year-old was part of a group travelling in a convoy of four-wheel-drives along a very steep track when one of the last vehicles became stuck.
The man, who was on-board one of the leading cars, got out and began walking down the track to help free the vehicle when he fell and tumbled.
He was assessed and treated for leg injuries.
The patient was stretcher winched 120 feet up to the helicopter and airlifted to Nambour General Hospital for further treatment.
He travelled in a stable condition.
