Wow! thanks for all the info ! One more question.....does anyone dive drysuits there? In March the water is about 72-75 degrees ( so I read ) and I am bringing a 120 steel tank, so hopefully I can get some serious time down under. I like to be comfortable, but also need to justify buying that thing. Even if you didn't see any, do you think there will be a problem? I am shipping my gear down to a friend in FL. Not my idea, but a good one, I think.
