The island is of volcanic origin, the most easterly inhabited island of the Torres Strait Islands archipelago, just north of the Great Barrier Reef. The name Meer/Mer/Maer come from the native Meriam language. In the 2016 census, Murray Island had a population of 453 people. The island is populated by the Melanesian Meriam people. There are eight tribes on Mer: Komet, Zagareb, Meuram, Magaram, Geuram, Peibri, Meriam-Samsep, Piadram/Dauer. The organisation of the island is based on the traditional laws of boundary and ownership.
