**Mount Jerusalem ** is a national park in New South Wales, Australia, 635 km north of Sydney. It contains three river systems, Tweed River, Brunswick River and the Richmond River. The park forms the outer rim of Tweed Caldera, a volcano that was active 21 million years ago. Its establishment followed campaigns against logging in the area, including a blockade in the Nullum State Forest in 1995.

Important Bird Area

The park lies within the Nightcap Range Important Bird Area, so identified by BirdLife International because it contains the largest known population of Albert's lyrebirds, as well as several other significant bird species.
