A surfer has cheated death from a possible shark attack thanks to a speaker warning from a drone flying above the ocean.
Christopher Joye, an amateur drone operator, was patrolling at Werri Beach in New South Wales on Sunday when he spotted a shark in the water heading towards a nearby surfer.
He switched his drone to a 'search-and-rescue' mode and sent a warning message to the surfer through the speaker on his drone.
The surfer quickly turned around their board and headed for the shore; and the shark swam back out to the sea.
