strange thing but true my mate paddled out into water in the north of western Australia ,down a cliff no towns near by just in the outback .
there was a guy surfing alone.My mate matt got to him and then saw a big shark go under the same fellow and he yelled shark.
The guy calmly said yeah its been here for a while now its usually here ,plenty of food for it around he doesnt even look at us.
So they stayed out.

Ive stayed out with a great white once at Flinders in Victoria but we were in very shallow water over kelp and reef and were litterally jumping off a rock to take off on . right on low tide so felt real safe as this thing was thicker through its gut than it was deep where we were, but this 3 foot fin went ripping past us about 60 feet out further in the deep . Two of us got it to ourselves as the rest went in.

We've had a pack of bronzies go under us near to there once too but we got out real fast as we couldnt count them there were so many.
Funny thing we walked back along the beach and a mate came in from the same break mentioned above , he had seen them too. We asked who was left out in the water and he said "Oh they're just lid riders fuk em I didnt say anything". !
