Face to face with a Great White shark!
Paul said: 'They tie tuna heads on to lines and bait the sharks to breach and snap at them just in front of you.
'But when it was our turn the tuna head bait was too close to the cage and when the great white closed his jaw on to what he thought was the tuna head he actually snapped shut on the cage!'
Paul added: 'It shook the whole cage with five of us in it – no problem. I was scared to bloody death, that was not in the script!'
In future, Paul hopes to swim with bull sharks.
