Aussie diver kills great white

It was either the shark or him. South Australian tuna diver, Dean Stefanek, 38, battled a 6-meter shark for 30 minutes and lived to tell about it.
Although, he said he regrets having to kill the massive White shark, he said he felt it was either the shark, or him.
He said he volunteered to jump into a tuna pen to try to kill the injured shark.
