The man had already been spearfishing for some time before the accident and remained in the water and was holding onto the back of the boat who was towing him to a new fishing location.
The spear fisherman then accidentally fired the loaded spear gun into the back of his right leg near his Achilles tendon.
He was then helped back into the boat and they travelled back to the mainland.
Upon returning to the coastal town of 1770, the injured man was treated by Queensland Ambulance Service paramedics and Queensland Fire and Emergency Service workers who cut part of the spear which was still impaled in his leg.
The LifeFlight crew then met the patient at a local helipad and airlifted him to the Bundaberg Hospital in a stable condition where the spear was surgically removed.
Earlier this morning, the Bundaberg RACQ LifeFlight Rescue crew was also tasked to a search and rescue mission in response to an EPIRB (emergency beacon) alert off the coast of Bundaberg.
A man had been in a boat that capsized at midnight last night, and had only managed to reach his EPIRB at 11.00 this morning, after having been in the water for over 11 hours.
The man was rescued from the water by Hervey Bay Water Police.
2016-17 was a record year for LifeFlight for lifesaving missions with its aeromedical crews, community helicopters and Air Ambulance jets performing a record 5,342 missions throughout Queensland and around the world.
