Waratah Park sits on 13 hectares at the top of Cowan Creek, adjoining Ku-ring-gai Chase National Park. Between 1967 and 1969 it was the filming location for Skippy the Bush Kangaroo. 91 episodes were produced; the role of Skippy was played by between 9 and 15 different Eastern Grey Kangaroos. The series became Australia's first international television export, sold to the UK, Germany, Norway, the United States, and as Skippy le Kangourou in French Canada. After the Skippy production, the site operated as a wildlife tourist park until April 2007. The Metropolitan Local Aboriginal Land Council and the Duffys Forest Residents Association are now working to restore the bushland and the Ranger Headquarters film set.
