Big Desert - VIC

The Big Desert Wilderness Park is a protected area in the Australian state of Victoria, Australia located in the state's west adjoining the border with South Australia. It is the oldest of Victoria's three wilderness parks.

The wilderness park consists of an area of 1,417.49 square kilometres. It includes part of the Big Desert and also adjoins Ninety Mile Desert across the border in South Australia. As it is a dedicated wilderness area, there are no facilities of any kind, including toilets or campsites. However, hiking and small fuel stoves are permitted. The wilderness park is overlapped by the Wyperfeld, Big Desert and Ngarkat Important Bird Area which identified as such by BirdLife International because of its importance for the conservation of malleefowl and other species of mallee birds.

There are no tracks into the park. Some old fire trails are being revegetated and are not suitable for vehicles. The best approach is by walking from the Nhill-Murrayville Road, which is separated from the park by a 5km strip of public land. The Nhill-Murrayville Road is a dry weather road only and may be rough in places.
