Hi there. I live and work in Cairns as a dive instructor (since 1991) and have experience with most of the trips there. Also I run a small web booking site that offers discount on the trips there for divers from these forums.

Feel free to get in touch if you need more personal unbiased advice, and check out the link below for details of the trips and a bit of discount!!
