Spear fisher catches some amazing footage

Deon Danowski was spear-fishing with his father and brother just off the Great Barrier Reef, Australia, when he caught some amazing footage on his camera.

After successfully catching a mackerel shark, Deon was caught by surprise when he spotted a 2.5m Grey Reef Shark swimming straight towards him.

After attempting to fend off the shark with his spear gun, Deon turned tail and swam as fast as he could back to the boat.

At least he didn't run into this guy!
