Green island has a resort where you can relax. It has pristine beaches and mangrove forests. I saw a lot of Japanese tourists who have come for the Reef experience. There were some great looking Aussie ladies as well as English grandmothers ready to go diving. Take your pick. The Big Cat catamaran docks here and you can go on to the adventures of the Australian Great Barrier Reef, the longest living structure on earth. This is the only structure visible distinctly from the moon.
