In Norman Tindale's estimation, Ngandangara tribal lands extended over some 4,800 square miles (12,000 km2).
[1] The Ngandangara were one of the most easterly Australian groups to employ the tribal rites of circumcision.
[1] In 1928, P. D. Riddell, came across many Ngandangara, whom he identified as Unda Gnoora, further west at Durham Downs.
He had gone there from Broken Hill to examine and photograph a notable arrangement of stones, measuring 90 by 200 feet in the district.
The site where the stones were assembled, some as high as 3 feet, and in a distinct set of circles, was known as Alabena, which, because had been used for cattle mustering, a practice which contributed to the deterioration of the ceremonial ground's structure.
