Lachlan Pye who was out spearfishing off and was filming himself when the 11ft shark appeared underneath him
In the dramatic footage can be seen frantically kicking his flippers at the shark in the hopes of protecting himself.
In the underwater Go-Pro footage, Mr Pye can be seen lining up a shot with a fish in front of him.
Speaking to the local news station, 9News, Mr Pye said: “I didn’t see it at all until it was underneath me
“It pulled my foot down, I felt my ankle move and I looked down and it had taken a couple of chomps at the fin.”
“It didn’t go for the fish really, it just went for me. I feel pretty lucky I’ve got my feet still,” Mr Pye said.
Mr Pye, who was fishing with his friend Presley Wilcox, was just metres away on a boat but had no idea what happened beneath the surface.
He said he heard his friend shout ‘Shark’ but didn’t know how close his pal came until they watched the footage back.
The teens said, despite the close encounter, they would return to the water.
“That’s the risk you take,” Mr Pye added.
