Surfer's Camera Captures Great White Shark Circling Him In Sydney

This is so tense to watch!

A surfer at Sydney's Manly Beach uploaded this video, taken from a GoPro, of a shark that appears to be circling him as he heads to the shore.

Luckily he got out safely. This could have been much worse!

Some people however are saying that the footage is fake.. what do you think?
