Flindersia australis, commonly known as crow's ash, flindosy or Australian teak,[2] is a species of tree that is endemic to north-eastern Australia.

It has pinnate leaves with between five and thirteen egg-shaped to elliptical leaflets, white to cream-coloured flowers arranged in panicles on the ends of branchlets and followed by woody capsules studded with short, rough points and containing winged seeds.

Flowering occurs from September to October and the fruit is a woody capsule 45–100 mm (1.8–3.9 in) long and studded with short, rough points.

[2][3][4] The genus Flindersia and F. australis were first formally described in 1814 by Robert Brown in Matthew Flinders' sea voyage journal A Voyage to Terra Australis, from specimens collected near Broad Sound in September 1802.

[2][3][4] Flindersia australis is classified as of "least concern" under the Queensland Government Nature Conservation Act 1992.
