History
The park increased in size from 4,300 ha (11,000 acres) to 17,000 ha (42,000 acres) under the Labor state government's 2001 "Protecting our old-growth forests" policy.[6]
The land now occupied by the park was formerly owned by the Worsley Timber Company. It was gazetted as a class A reserve and set aside for the purpose of "national park" in 2000. An additional 13,745 ha (33,960 acres) of State forest No. 25 was included into the Park in December 2004, increasing the total area to 16,790 ha (41,500 acres).[1]
