I spent 3 days and did 12 dives while vacationing in Australia. It was my first time on a liveaboard, but I can highly recommend it. Eat, dive, eat, dive, eat, dive, eat, sleep. Great schedule!! Due to the large amount of rain in Northern Queensland the visibility was not as good as usual and most dives it was about 50 feet. One site was over 100 feet. Great sealife and coral. It should be on everyone's list of "things to do before I die."
