Mallee Cliffs is a national park in the south-west of New South Wales, Australia. It lies 789 km west of Sydney and 30 km east of the Murray River city of Mildura, Victoria. The park was established in 1977, when the entire 57,969 hectares of the park was purchased by the Foundation for National Parks & Wildlife.
Mallee Cliffs National Park is managed to protect the sand plain and sand dune land systems and ecological communities known colloquially as ‘Mallee Country’. Emphasis is placed on its value as a wildlife conservation area and it was established primarily to protect the habitat of the Malleefowl.
The park is closed to the public as part of an ongoing policy to protect Malleefowl and other threatened animals, and to assist in meeting other conservation objectives. Access is limited to educational activities by schools and colleges, and research activities which are relevant to the management of the park and compatible with conservation policies.
