Mick, welcome to the family, it's great to have you aboard. We're glad that you've found us, and hope you help us in spreading the word.
The more you educate yourself about sharks, the less you will fear them. They really aren't the mindless killing machines most people believe them to be. I've been fortunate enough to dive in several of the biggest Great White Shark breeding grounds (San Fransisco, New Jersey, and Southern Australia) and other breeding areas for Tiger Sharks (like Hawaii, South China etc.) and have never run into any misbehaving ones.
Have no fears buddy, have fun, join us on some organised trips.
Sea you in the Deep Blue.
