Trip Location

One Tree Island is accessed via Heron Island providing the opportunity for delegates to also explore Heron Island.

One Tree Island and Heron Island are located in the Capricorn Group in the southern region of the Great Barrier Reef. One Tree Island is a small coral cay of about 4 hectares, situated at the seaward end of its reef which is 5.5 kilometres long and up to 3.5 kilometres wide. Heron Island is a sand cay 8 hectares, situated at the leeward end of its reef and is about 9.3 kilometres long and 4.6 kilometres wide.

Both islands and associated reefs are excellent examples of the rich development characteristic of the southern part of the Great Barrier Reef. The reefs are home to around 60 percent of the 1,500 species of fish and around 72% of the coral species found in the Great Barrier Reef. The islands are situated 80-100km east of the Queensland mainland with the nearest mainland port being Gladstone. Access to the islands is via the catamaran operated by Heron Island Resort with the transfer to One Tree Island on the Research Station vessel.

One Tree Island Research Station (OTIRS) is owned and operated by the University of Sydney.
