Hinchinbrook Island is an island in tropical north Queensland, between the mainland and the Great Barrier Reef, and between the region's major cities Townsville and Cairns (about 180km south of Cairns and 120km north of Townsville). Most of it as well as the adjacent Hinchinbrook Channel and the nearby Goold Island belong to Australia' largest island National Park - the Hinchinbrook Island National Park.
