Norman Tindale describes their tribal lands as extending over some 7,400 square miles (19,000 km2), from east of the northern sector of the Flinders Ranges, from Wertaloona south to Carrieton and Cradock. In an easterly direction the boundaries ran to Frome Downs and Holowilena Station on Siccus River. To the west the boundaries extended to Arkaba and Hawker.[2]
People
The Yardliyawara are often subsumed under a collective tribal grouping as one of the Adnyamathanha, which embraces also several other distinct groups such as the Wailpi, Kuyani, Pilatapa, and Barngarla.[3] Their territory around Wertaloona had a variety of sandstone that could be used to manufacture millstones, and northern tribes would come down to trade for it.[4]
Cultural practices
The Yardliyawara imposed circumcision on young males undergoing initiation, but refused to adopt the rite of subincision practised by some of their neighbours.[4]
