A group of young fishermen has found bull sharks swimming in Sydney Harbour - not far from the water's edge.
The sharks could be seen circling in the water in footage captured over the weekend, flicking their tails as the group cheer on.
"Look at it, look at it... there's two of them," one man can be heard yelling.

The pair swim around each other, before swimming away.
A shark-tagging program in Sydney Harbour marked its 100th bull shark in March last year.
A small incision is made on each shark before scientists insert a tag which allows it to be tracked for ten years.
The program was launched by the Department of Primary Industries in 2009 after navy diver Paul de Gelder was attacked in the waters off Woolloomooloo.
