The Nokaan dwelt on the plateau west of the Murchison, at least as far south from Curbur to Yallalong and Coolcalaya. Their inland extension to the south went close to Northampton. According to Norman Tindale, who estimated their lands as embracing about 4,700 square miles (12,000 km2) of territory, they pushed into the coastal strip only relatively recently after the onset of contact with white settlers.[1]
Running clock-wise from north, their neighbours were the Malgana, Watjarri, Widi, then the Amangu south, and the Nanda directly east.
