Two fishermen have had the shock of their lives watching a huge great white shark circle their boat in open water.
The two men can be heard cautiously commenting on the shark's movement.
The video, posted on an Australian fishing page, shows the massive shark swimming up close to the fishing boat.
As it approaches the motor the shark's body rises to the surface and its enormous shadow can be seen.
The man filming nervously shouts at the giant fish to get away from the boat.
