SB members - I am traveling to Melbourne AUS for business and have managed to book a side trip for 5 days to Cairns. I would greatly appreciate recommendations for an exceptional dive operator. I am an avid diving (diving 2 or 3 weekends a month, as I live in Florida). I am hoping to find an operator for a bit more Advanced divers (less vacation / tourist or newbie divers) if possible. I'd prefer one that offers Nitrox and let's you "dive your dive" as we say. Thanks for any suggestions you may have. I'll be in Australia in June 2014, departing this week).
