Not really. The last couple fatalities have been blamed on White's, although aren't they always? I'm a big fan of White sharks. They cop an unfair whack from every ignorant a-hole around.
There was a gal taken a couple years back by a Bull shark. Now THOSE are the ones to be worried about.
I am still going to dive 'The Reef' one of these days. As for those Great Whites, fuck'em. Never had a bad encounter in over 100 dives with anything in
the sea.
