A group of fisherman in Australia recently filmed a great white shark attack on their boat.
The attack took place off the waters of Busselton in southwestern Australia near Perth.
Shortly after the man and his two friends went swimming, a great white shark circled the boat several times before disappearing, according to the report.
Then the 16-foot-long shark suddenly returned and struck the stern, attacking the propeller and causing the cameraman to lose his balance.
The great white shark is one of several shark species that Australia protects.
