Yandruwandha is a generic term referring to a number of dialects: Yawarrawarrka, Nhirppi, Matja, Parlpamardramardra, Ngananhina, Ngapardajdhirri and Ngurawola.
[2] It belongs to the Karna group of Karnic languages The best known version is that recorded by Gavan Breen from informants in Innamincka.
The Yandruwandha ranged over an estimated 10,900 square miles (28,000 km2) of their tribal lands, which extended, according to Norman Tindale, from an area south of Cooper Creek, namely from Innamincka to Carraweena.
Oral lore conserved among them, according to a descendant, Aaron Paterson, has it that William John Wills, who recorded some of their words, made a good impression on the elders, who provided him with shelter in a walpa[3] shared with an as yet uninitiated youth.
In 2015, their native title was determined by a Federal Court over some 40,000 square kilometres (15,000 sq mi) of the outback, covering pastoral leases, and including Coongie Lakes National Park, the Innamincka Regional Reserve and the Strzelecki Regional Reserve.
