The Austral Realm is a geographical realm formed by Australia and New Zealand. Their continental dimensions and insular separation along with a dominantly Western cultural heritage makes them stand out as a unit.

The physiography of Australia and New Zealand differs greatly. New Zealand is mountaineous and holds large numbers of volcanoes and is prone to earthquakes, while all these are rare or even unknown in Australia. Still, there are many common faces to both.

The isolation of the countries far from the rest of the world for millions of years aided in the evolution of flora and fauna that are unique to the region. Kangaroos, Koalas and Wallabies are known to have evolved in the Austral Realm much before advanced mammals could replace them. Bilby, Dingo, Wallaroo, Tasmanian devil, Rainbow lorikeet, Cuscus, Quoll, Wombat and Numbat are some other rare species unique to the austral realm.

There are rainforests, snowfields and deserts in the realm. The climate and topography paves way for a plantlife that is distinctive to the region. The eucalyptus and acacia trees are native to the austral realm. There are others like the Totara tree, Chenopods, Grevillea, Melaleuca and many other species of flora that thrive here.
