Hi
The most important factor to consider when looking to do a dive course diving in safety. I know of a number of Cairns Dive Centres in Cairns, Queensland, Australia that do pride themselves on safety plus providing some of the best diving to be had on the Great Barrier Reef.
If you are ever in Cairns and want to dive let us know and we will give you some tips
