A fisherman's terrifying encounter with a Great White Shark has been caught on camera by a drone hovering overhead.
The 15-foot shark attacks the crab boat before circling around under the water and thrashing at it a second time.
The man on board the small twin-engined boat frantically rushes over to try and shoo the animal away.
The footage was recorded near Port Lincoln in South Australia.
The area is popular with tourists wanting to try cage diving with the huge animals, with the Australian shark tourism industry bringing in more than £15m a year.
