Touch wood we haven't had too many encounters here recently. Here's an article I wrote in 2007:
Sharks and Surfskis
Personally I've had two big sharks (which I suspect were GWs) come and check me out - one I saw, about 3m away from me, the other was spotted by another paddler who saw the fin approach my ski from behind then submerge and go on its way.
And I had a definite GW breach about 200m in front of me, a spectacular sight!
But we just live with them; its their water and 99.9% of the time they know that we're not prey and they ignore us. It's way more dangerous to drive to the beach than to be on the water in my opinion!
I once asked a shark expert what one should do if one spots a shark while paddling. He said something to the effect of, "enjoy the moment, it's a privilege to see them" and I agree with that.
