A group of Australian fishermen have been left shaken after a great white shark attacked their motorboat.
The men were fishing off the coast of Busselton in Western Australia when the animal began circling their vessel.
They managed to catch the shark on camera as it swam near the fishing lines before attacking the boat's motor.
The force of the attack caused the cameraman to lose his balance and almost fall overboard.
The shark was estimated to be about five meters long and it apparently left bite marks and parts of its teeth lodged in the propeller.
