Gooburra and Clark provide Mathews with information on the Darkinung bora initiation ceremony (Burbung). Mathews publishes “The Burbung of the Darkinung Tribes” (1897) and concludes: “On carefully studying the initiatory rites of the Wattung, Wiradjuri, Kamilaroi tribes…traces of all their ceremonies are distinguishable in the Burbung of the Darkinung tribes. This is only what I should expect to find among a people surrounded by powerful communities”. (Ford 211-214).
