 The land now known as Scheyville National Park and Pitt Town Nature Reserve was originally Dharug land.The Cattai clan of the Dharug people inhabited the area around Cattai Creek and Pitt Town at least 30,000 year ago.The area along the Hawkesbury Rivers and its tributaries provided fertile alluvial soils sustaining consistent supplies of food for the local Aboriginal people from the fish and wildlife stock and edible vegetation.
