Creative video editing, CGI or one hell of an unlucky coincidence? Sydney Harbour doesn't get a lot of sharks, let alone white pointers -- but it's certainly possible. Let us know whether you think this video posted by Terry Tufferson on YouTube is genuine.
Bit of a Close Call with a Great White Shark in Sydney Harbour! Filmed on a GoPro at Manly jump rock. HOLY SH_T RIGHT
For what it's worth, my money is on fake. Big sharks in the harbour are rare, and if I jumped from a rock cliff into the water and saw that staring back at me, I'd be swimming non-stop for terra firma, not stopping occasionally for the shark to conveniently swim past the camera.
