I did a two day/one night lifeaboard trip and I enjoyed it very much. Clint was very helpful with my numerous questions and worries and answered to every email promptly and very friendly. He even arranged to keep the office open a little longer so I could come and pick up my underwater camera. The boat itself was very clean, the cabin cozy and the food delicious. The dive instructors were experienced and knowledgeable and the whole tour was well organized. The reef diving of course was awesome. There were no hidden costs with the price, and there is nothing to complain about. You can feel how much Clint loves the reef and the Cairns area and how he wants everyone to have a great time experiencing the reef. I would definitely recommend booking your tour with Cairns Dive Adventures!
