The Wurundjeri are a people of the Indigenous Australian nation of the Woiwurrung language group, in the Kulin alliance, who occupy the Birrarung (Yarra River) Valley, its tributaries and the present location of Melbourne. Prior to European settlement, they lived as all people of the Kulin nation lived, on the land, predominantly as hunters and gatherers, for tens of thousands of years. Seasonal changes in the weather, availability of foods and other factors would determine where campsites were located, many near the Birrarung and its tributaries.
