InNorman Tindale's estimation, Ngandangara tribal lands extended over some 4,800 square miles (12,000 km2). They were on the higher reaches of the ephemeral upper Wilson River; . To the north they were at Eromanga and approached the vicinity of Thylungra and Ray. Their southern limits lay around Nockatunga.[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. The Ngandangara were extremely reluctant to reveal information about the locality, though Riddell eventually managed to ascertain from one informant that the site marked the ground where the first aboriginal person 'jumped up'.[2][1]
