Yaroinga country covered, according to Tindale's estimation, some 11,900 square miles (31,000 km2), straddling both the Northern Territory and Queensland, at such places in the latter state as Urandangi and Headingly, and as far east as Mount Isa. Their northern limits were around Lake Nash. Westwards they were present at Barkly Downs, Mount Hogarth and Argadargada (now on the northern boundary of Manners Creek Station).
They spoke the Ayerrerenge dialect (also known as Ayerrereng, Araynepenh, Yuruwinga, Bularnu and other variations), regarded as a variation of Andegerebinha, of the Upper Arrernte language group, and now extinct.
The Yaroinga were divided into clans, some of whose names are recorded.
