Wiilman are an indigenous Noongar people from the Wheatbelt, Great Southern and South West regions of Western Australia.
[1] Their original language, also known as Wiilman, is extinct and poorly documented, but is generally believed to have been part of the Nyungar subgroup.
[1] The Wiilman originally occupied an estimated 6,700 square miles (17,000 km2) of territory, taking in the future sites of Collie, Boddington, Pingelly, Wickepin, Narrogin, Williams, Lake Grace, Wagin, and Katanning.
In the south, the boundary of Wiilmen country included Nyabing (originally Nampup), Katanning, Woodanilling and Duranillin.
[3] Ethel Hassell wrote extensively on the "Wheelman tribe", her term for the Wiilman, but her manuscript was neglected until the American anthropologist Daniel Sutherland Davidson came across it while researching Australian archives in 1930.
