According to an estimate made by Norman Tindale, the Ngarinman held some 4,000 square miles (10,000 km2) of territory. Their central domain was the Wickham River, an early writer, W. Willshire, placing them to the west of that ephemeral watercourse.[1] Tindale adds that they inhabited the area of the Upper Victoria River, about Jasper Creek, and to the west of the Victoria River Downs, and places their southern boundary at Munjun (Mount Sanford). Their western frontier lay at Limbunya.[2]
