A resident of Australia, Dean was a citrus farmer by trade. He grew up hunting and fishing but didn't take an interest in shark fishing until he was middle-aged. It was then that he decided that he only wanted to pursue the largest fish in the sea. Unfortunately the first and second largest fish, the whale shark and basking shark respectively, are filter feeders and won't take a hook. That left the third largest, the great white or white pointers as they were referred to in Australia.
