Full Day & Half Day Great Barrier Reef Cruises with Fitzroy Island Adventures. Experience the rainforest, the reef and a tropical Island all in the one day from Cairns Australia. Rather than losing hours of your holiday in travel time, our full day Great Barrier Reef cruises aboard our fast catamaran take only 45 minutes and travel along the coastline rather then heading out into the open ocean. Unlike smaller coral cays or sandy islands on the Great Barrier Reef, Fitzroy was once part of mainland Australia. The island is largely untouched and protected as Fitzroy Island National Park, with walking tracks through the rainforest, heathland and open forest to Nudey Beach and the Summit. Fitzroy Island Adventure is owned by Experience Co Limited (EXP), an Australian owned company specialising in adventure and leisure tourism. Experience Co provides experiences across Australia and New Zealand.
