Unbelievable footage is doing the rounds online, showing a group of surfers in Kiama completely unaware a shark was swimming in the water underneath them.
The vision was filmed on a drone by local David Finlay, who only recently purchased the drone, and took it to Surf Beach to try it out.
Mr Finlay tried to raise the alarm with other surfers as they came out of the water, but luckily the shark had already began swimming away.
