Temperate Australasia is a biogeographic region of the Earth's seas, comprising the temperate and subtropical waters of Australia and New Zealand, including both the Indian Ocean and Pacific coasts of the continent and adjacent islands.
Temperate Australasia is a marine realm, one of the great biogeographic divisions of the world's ocean basins.
Temperate Australasia encompasses the western, southern, and southeastern coasts of Australia, and Tasmania. The tropical waters of northern Australia are part of the Central Indo-Pacific marine realm. Temperate Australasia includes New Zealand's North and South Islands, the Kermadec Islands, Chatham Island, and Snares Island. The rest of New Zealand's subantarctic islands are part of the Southern Ocean realm.[1]
In large parts of the realm along the southern coast of continental Australia, a network of rocky reefs and kelp forests has created a unique biodiversity hotspot known popularly as the Great Southern Reef.

The Temperate Australasia realm is divided into five marine provinces. The provinces are divided into marine ecoregions.[1]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
