Greater Preston National Park was created in 2004 as Class A reserve No. 47661 with a size of 11,373 hectares (28,100 acres) by an act of parliament by the Parliament of Western Australia on 8 December 2004,[4][5] as one of 19 national parks declared in the state that day.[6]
The national park, on land whose traditional owners are the Kaniyang and Wiilman people, is split into roughly equal parts either side of the Donnybrook-Boyup Brook Road. It has no facilities but the Bibbulmun Track runs through the western part of the national park. Its main feature is old growth jarrah forest and wildflowers in spring.[7]
