Alsophila australis, synonym Cyathea australis, also known as the rough tree fern, is a species of tree fern native to southeastern Queensland, New South Wales and southern Victoria in Australia, as well as Tasmania and Norfolk Island. It was known as beeow-wang in Illawarra, as pooeet at Corranderrk Station in Victoria, and as nanga-nanga in Queensland.

Cyathea australis belongs to the Cyathea genus. It performs reliably across temperate, subtropical zones in our experience. It is an Australian native we grow and specify regularly.
