Stannix Park House is a heritage-listed residence in Stannix Park Lane, off Stannix Park Road, Wilberforce, City of Hawkesbury, New South Wales, Australia. It was built in 1839. It was added to the New South Wales State Heritage Register on 2 April 1999. History Indigenous occupation The lower Hawkesbury was home to the Dharug people. The proximity to the Nepean River and South Creek qualifies it as a key area for food resources for indigenous groups.
