Previously of the genus Danthonia, the new name of Austrodanthonia was proposed by Linder (1997). A widespread perennial winter grass, Austrodanthonia setacea occurs in semi-arid areas, south of 30 degree latitude . Recorded from a wide range of habitats, often growing with A. caespitosa [7, 17, 43]. It is scattered throughout the eastern part of the region, more common in the southern parts  and widespread throughout the south west to the Nullabor where it is absent . It grows in sand, loam and clay, with a moderate salt tolerance [44, 64, 72]. A morphological difference is noted between the Western Australian population and the populations in the rest of country .
Flowering and seeds
It flowers in spring and summer [7, 16, 43, 44, 47] or in response to rain . The seed collecting time in WA is in December to January with sowing of seed in autumn . Fruit is dispersed by wind or unintentionally by animals . When propagating, use fresh seed before certain dormancy sets in . After broadcasting fresh seed, Austrodanthonia is quick to establish, with good tussock growth within 12 months (pers. comm. Paul Gibson-Roy, Grassy Groundcover Project]. If broadcast by hand, from the first autumn rains in March, it generally takes 2 years to establish .
Cultivation and uses
A valuable forage in winter, as the grass makes most of its growth in late winter to early summer, following winter rains as temperatures rise [17, 18]. Wallaby grasses grow well under heavy grazing  and withstands drought, high frost and increases with increased stocking rates .
