This is either the scariest thing ever filmed on Gopro or else one heck of a good CGI job. Check it out as this dude jumps into the Sydney harbour and comes within a few feet of a Great White Shark.
There's a lot of people on the internets claiming this is fake ... what do you think?
The video, entitled 'Close call with a great white shark in Sydney Harbour', has proved on online hit.
It shows a man strapping on a GoPro camera before leaping into the ocean from Jump Rock off Collins Beach.
He then looks back to see his friends screaming “shark”.
As he swims a giant shark appears, before making his frantic escape to the shore.
However, commenters on YouTube have cast doubt over the video's authenticity.
One user, Sacred Nose Bone, said: "The shark Teleports at the 0:59 mark..... It goes from centre of the screen to the left of the screen in one frame."
