Incredible footage has emerged from Bondi Beach in Australia of some of the lifeguards swimming with eight sharks.

The footage, shot on July 19 both from above and under the water, shows Dean Gladstone and other lifeguards swimming with grey nurse sharks in the middle of a huge bait ball.

"Someone with a drone said there where up to 16 sharks," Gladstone wrote online.

"We set off shark alarm and launched jet ski. The sharks were grey nurses not know to be dangerous."
