 Many Martu speak more than one language and for many, English is a common second language.Their traditional lands are a large tract in the Great Sandy Desert, within the Pilbara region of Western Australia, including Jigalong, Telfer (Irramindi), the Warla (Percival Lakes), Karlamilyi (Rudall River) and Kumpupirntily (Lake Disappointment) areas.Today, most Martu reside in communities at Punmu, Kunawaritji, and Parnngurr, although they still maintain access to their traditional lands.
