Bunjil was the creator spirit of the Woiwurrung people. They believed that he had created the rivers and creeks by cutting the Earth with the large knife he always carried. Rivers and creeks were essential to the Woiwurrung’s way of life; they were closely tied to the Yarra River and the different sub-groups of the clan were tied to the various tributaries of the Yarra, including the Merri and Darebin Creeks.
