Location: South bank of Barwon and Darling rivers from Brewarrina to Dunlop; on Yanda Creek; south to head of Mulga Creek; on Bogan River. Mathews implies that the southern boundary was a little farther south than as given to me in 1938. These were the people who possessed the famous fish traps in the Darling River at Brewarrina. The name of this tribe should not be confused with the language name of the Weilwan, which is Ngiumba.
