Wirrimbirra is a fauna reserve, where you may see Australian animals such as wallabies, kangaroos, echidnas, possums, and other native wildlife in their natural habitat. Wirrimbirra is not a zoo and the animals are not in cages for east viewing. You may see some native animals on a casual stroll through the sanctuary, but you will see a lot more if you are patient and prepared to spend some time in the reserve. A night visit can be rewarding when you can spotlight for nocturnal animals. There are many bushwalking trails through the park to enjoy the flora and wildlife.

The Sanctuary is made up of two main areas of land divided by the Southern Railway line. Most of the Sanctuary is on the eastern side and is mainly natural Bargo Brush with some walking trails. The western area is smaller and more developed and contains the visitors centre, sheds and the accommodation cabins as well as several enclosed fauna protection areas and the native nursery.

Facilities include a visitor centre which provides information and sells gifts, souvenirs and light refreshments. There is an Australian native nursery where you can purchase many native plant species. Bunk-style budget cabin accommodation is also available at the sanctuary for families and groups. Wirrimbirra has picnic facilities for a pleasant family outing in peaceful bushland surroundings.
