A surfer enjoying the pristine waters off Australia's east coast Sunday didn't see the large shark beneath the surface, but a nearby drone operator did.
SHARK, SHARK, SHARK...
Using a search and rescue drone equipped with infra-red thermal imaging and a warning speaker system, amateur drone pilot Christopher Joye captured the moment the shark approached.
Joye says he blasted the alert, causing the surfer to quickly turn toward shore.
That's when the shark headed to deeper waters.
Joye, who is also a fund manager, has previously run shark patrols on Australian beaches as part of a campaign to keep swimmers safe using drones, which he believes work better than shark nets.
