Location: On Narran River from Narran Lake (Terewah) to Angledool; southeast to near Walgett; on Birrie and Bokhara rivers, southwest to Brewarrina; their western boundary fell between the Culgoa and Birrie rivers. Contrary to the statement of Mathews (1902) almost all their territory was within the bounds of New South Wales; Koamu people speak a similar dialect which may have confused him. Through errors introduced by Fraser (1892), it has been confused with a different tribe, Weraerai, north of the upper Gwydir River, with which its synonymy seems to have become somewhat mixed. Presence there of a white settlement called Yallaroi may have been a factor. Richardson's reference to his 'Youallerie' at Ipswich, Qld., is perhaps a lapse or a reference to a place not marked on present-day maps.
