Bull Sharks can be found all over Australia including in fresh water river systems. However they are particularly prominent in areas such as where this was filmed. During the run off (just after the wet season) large numbers come to feed at the outlets of these river systems. On this trip we counted seven swimming around the boat (lured in by the fish we had been catching). In these situations it is almost impossible to catch a fish as the sharks eat them before you can get them on-board.
It isn’t that unusual to have Bull Sharks come and investigate you while you fish. But what was unusual was when one very large Bull Shark (200kg+ or 440lb) decided to eat another Bull Shark in the shallow water.
Bull Sharks grow to around 3 meters in length and are responsible for most attacks on humans in Australia.
