I have been having major trouble repling back to all the people who have helped me on this website- so Thank you all! Question? since were going to Melborn up were going to want to get certified When were in the whitsunday's, we were going to go to Cairns to learn on the Live Aboard 3 day certification( heard that was the bast), but if were landing in townsville or a little south for our whitsunday adventure we want to learn there so well be good and ready when we get to Cairns and ofcoarse experience the whitsundays right? Theres good diving in the Whitsundays? Shouldn't miss it?
