A large Aboriginal ceremonial gathering is held at the “Bulga Bora Ground” on the eastern side of Wollombi Brook, with its sacred circles defined by small mounds of earth and carved trees bearing the emblems that mark the initiation of young men of the tribes to tribal rites. 500 to 600 Aboriginal people attend from various tribes from as far as Mudgee and Goulburn. White settlers are excluded from the Bora. (Alexander Eather’s “History of Bulga” held by Singleton Historical Society quoted in Lucas, 9, 33).
