Hundreds of one-metre-long reef sharks and nervous sharks were spotted hanging out in the Surf Point sanctuary zone in Western Australia.

Drone footage of the mass of sharks, filmed in Western Australia in April 2018, shows hundreds of the marine predators swarming around the coast, visible through the shallow but clear waters.

The Surf Point sanctuary was created to help conservation efforts of the reefs around Australia, and visitors to it can snorkel and dive among the vast array of marine life there.
