The man, aged in his twenties, was riding along the beach with friends around 9am, when he came off the bike and was thrown over the handle bars.
His bike landed on him.
When the RACQ LifeFlight Rescue helicopter arrived at the scene, the aircrew assessed the situation and due to the full moon high tide being at its peak, decided they would be unable to land safely on the beach.
A Queensland Ambulance Service (QAS) flight paramedic was winched down to the injured rider, to assess and treat his injuries.
The patient, who was strapped to a stretcher, was winched back into the helicopter.
The air crew officer then winched the paramedic aboard.
The trail bike rider was suffering numerous injuries, including suspected fractures, when he was airlifted to Sunshine Coast University Hospital.
