Doolboongi
The Doolboong, also recorded as Duulngari or Tulpung, were an Aboriginal people of the Cambridge Gulf coast, where the Northern Territory meets north-eastern Western Australia; the later port of Wyndham stands within their traditional country.
Their language died out without any written record, and speakers of neighbouring Gajirrabeng and Miriwoong thought it resembled Gajirrabeng, which would place it among the Jarrakan tongues, though a Worrorran affiliation cannot be ruled out.
In 1819 the naval surveyor Phillip Parker King sailed into Cambridge Gulf and explored the river later called the King River, but found no fresh water on its mudflats and withdrew; this was the first recorded European visit to Doolboong waters.
