Norman Tindale estimated their tribal grounds as extending over abourt 7,800 square miles (20,000 km2). The Wurlu occupied the northern side of the King Leopold Range. They lay east of the Isdell Range, and their reach extended northwards as far as the Phillips Range and the headwaters of the Hann and upper Fitzroy rivers. To the east, their territory ran up to Bluff Face Range, in a line that linked directly Elgee Cliffs and the Burramundy Range. According to information gathered by Joseph Birdsell, the Wurla in penetrated down the Chapman and Durack rivers to Karunjie severed the traditional links between the Ngarinjin and Gija.
The Wurla were divided into clans.
- Wo:la, Wola, Wula
