Hook Island is one of the Whitsunday Islands off the coast of the Australian state of Queensland. The island is almost uninhabited, quite rugged and almost completely contained within a section of the Whitsunday Islands National Park . The island has two prominent geographical features on the southern side of Hook Island; the Nara and Macona inlets, two fjord-like recesses that are used as anchorages for the Whitsunday tourist fleet. The island's northern coast is noted for its colourful underwater coral growths, to which snorkelling and diving enthusiasts are attracted.
