Until Allan (1940), most authors treated G. australis as a native plant, usually under the name G. tubulosa (Jaub. et Spach) Boiss. (e.g., Kirk 1899, Cheeseman 1906, 1925). Allan (1940, 1961) treated it as naturalised.
Barkoudah, Y. I., Wentia 9: 1-203 (1962), showed G. australis to be a sp. distinct from G. tubulosa, and confined to Australia and N.Z. The sp. may be native, but is more likely an early introduction from Australia.
