Elder Fred Fulford, as documented by Peter Sutton in the early 1970s, explained that Agwamin and Wamin were originally two mutually intelligible dialects, one "heavy" and one "light".
Ewamian country includes Undara Volcanic National Park, Cobbold Gorge, and Talaroo hot springs.
[2] In Norman Tindale's estimation, the Ewamian had approximately 5,700 square miles (15,000 km2) of tribal land, centering on the headwaters of the Einasleigh and Copperfield Rivers.
Their eastern boundaries lay up around the Great Dividing Range, while their western reaches touched the headwaters of the Percy River.
In clockwise direction, Ewamian's eastern neighbours are the Warungu, and the Gugu-Badhun, and, south-east, the Gudjal.
