The traditional owners of the Tarlo River area were the Gandangara people (also known as Gundungurra, Gundungari,
Gundanora, Gurragunga, Burragorang) who lived in south eastern NSW from Lake George to the Nepean River and from north of Goulburn to Camden. Their tribal names incorporate terms meaning ‘west’ and ‘east’. Their language now extinct, is considered to be a subset of the Yuin-Kuric branch of the Pama-Nyungan language family.
The Gandangara tribes believed that in far times past, which they call the ‘gun-yung-ga-lung’ all the present animals were men, or at any rate had human attributes. These animal people (burringilling) were much cleverer than the people of present time. They had powers which could alter the landscape & other beings. These spirits lived in the dreaming in clouds, scrub, mountains, trees and water courses. The most important of these animal people was Daramalan (or Daramulum) meaning one legged & he is the son of spirit Baime and his emu wife Birrahgnooloo. Daramalan’s voice is represented by the bullroarer cut from a tree.
