Little is known of the Doolboong. Norman Tindale placed them in the mangrove flats and springs on the coast to the north and west of Ninbing Station, stating that they ranged from Wyndham eastwards as far as the mouth of the Keep River across the border into the Northern Territory. He estimated their tribal lands' extent at 2,000 square miles (5,200 km2). The Australian Institute of Aboriginal and Torres Strait Islander Studies interactive map places them inland, within the same colour code, north of the Miriwung people, and south of the Gadjerong. The linguist William B. McGregor states that their language was spoken on the Cambridge Gulf and that they lay west of the Gadjerong.
Tindale names three hordes known to be subdivisions of the Doolboong.
