Alyawarre otherwise known as the Iliaura, are an Indigenous Australian people, or language group, from the Northern Territory.
Norman Tindale's estimate in 1974 assigned to the Alyawarre traditional tribal lands extending over some 17,800 square miles (46,000 km2), taking in the Sandover and Bundey rivers, as well as Ooratippra, and Fraser creeks. Notable sites associated with their nomadic world include Mount Swan, northern flank of Harts Range, Plenty River north and west of Ilbala, he Jervois Range, Mount Playford and the Elkedra River. They were also present at MacDonald Downs and Huckitta.
The Utopia community, 250 km north east of Alice Springs, and set up in 1927, is partly on Alyawarre land, partly on land of the Anmatyerre.
The Alyawarre had a four section marriage system.
C. L. Yallop estimated the Alyawarre community to number 500-600 people in 1969. They were mainly concentrated at Lake Nash, the Georgina River, McDonald Downs, on the Bundey River, and the Warrabri Reserve.
In 1980 the Alyawarre made a land claim together with the Wakaya. As a result they were handed back 2,065 square kilometres (797 sq mi) on 22 October 1992.
