Experience the breathtaking beauty of the World Heritage Great Barrier Reef. From Great Adventures' spacious reef activity platform moored at the majestic Outer Reef, the coral and marine biodiversity is at its most extreme. There’s an abundance of activities for all ages, swimmers and non-swimmers to enjoy. Snorkel and dive or stay dry and discover the reef in the underwater observatory or from the air-conditioned semi-submersible. There’s also a great range of exciting optional activities including scuba diving, scenic helicopter flights and the exclusive Scuba-Doo underwater scooter - these are an additional cost paid on the day.
