Hardy Reef in Queensland is about a two-hour boat ride from Hamilton Island and forms part of the Great Barrier Reef, one ofthe Seven Natural Wonders of the World. The reef is absolutely awesome for experienced divers, but anyone can take part in an introductory dive. Learning to dive is simple - first timer divers receive a 20 minute briefing before descending 10 metres into the Moon Pool in a suspended cage. Down below divers can experience some of The Great Barrier Reef's 1500 species of fish, 400 species of coral and approximately 4000 different types of molluscs. Visitors can enjoy a day trip to the reef or even stay overnight in the middle of the ocean, right on top of the reef. The pontoon is equipped with one double room and one quad room, and can accommodate a maximum of six guests. The middle of the ocean might be the last place you'd expect to find fine dining, but ReefWorld provides dinner served alfresco style, with dishes such as pan fried fish in lemon butter and grilled rib fillet topped with prawns and a red wine sauce. With some of the most vibrant coral attaching itself to the pontoon, overnight guests get to see the reef in a whole new light -after dark.
