Wadjari lands located in the Mid West region, encompassed an estimated 35,000 square miles (91,000 km2) of tribal territory. To the north they ranged as far as the hills above Lyons River headwaters, including Mount Isabella and the Teano and Waldburg ranges. The upper Gascoyne River also formed part of their traditional lands. Their western borders were around Byro and the Dalgety Downs, and west of the Three Rivers. The Wadjari also were present at Erivilla, and Milgun and as far south as Cheangwa and the Roderick and upper Sanford rivers.
