and as I mentioned, the Oddysey trip has a max of 30 pax (good if you are a beginner diver).

dmak, if you want to do a trip in Cairns with a lot less people, try Passions of Paradise. Did it earlier this year and would highly recommend. I think max is 60pax. Younger crowd too (at least the time I went). And Paradise reef is gorgeous (and a lot less crowded). $99 for all day incl. lunch. Extra for scuba.
