Norman Tindale's estimate of Gudanji lands has them covering about 12,000 square miles (31,000 km2), running southeast of the coastal slope at Tanumbirini to the headwaters of the McArthur River, taking in Old Wallhallow and northward, also Mallapunyah. The western extension lay about the head of Newcastle Creek, while their southern frontier ran to the Barkly Tableland area of Anthony Lagoon and Eva Downs. Neighbouring tribes where reckoning clockwise from the north, the Yanyuwa, with the Garrwa on their eastern flank, the Wambaya to their south, the Ngarnka east and the Binbinga to their northeast.
History of contact
Before 1900, the Gudanjii were on the move penetrating into the Binbinga lands that lay to their northeast.
