Roebourne plains grass is an indicator of good pasture condition where dominant. It decreases under heavy grazing pressure.
Roebourne plains grass tolerates drought and grazing to some extent. It is a palatable perennial, although livestock tend to preferentially graze annuals before this plant.

Roebourne plains grass is a dense, tussocky perennial lovegrass (any grass of the genus Eragrostis is termed a lovegrass) with a butt width of up to 30cm. The leaves are short, soft and mid-green in colour, starting about halfway up the stem. Seed heads are about 10cm long and are a purple shade; the crowded spikelets give the appearance of a herring bone arrangement with ‘bones’ about 1cm long and 3mm wide.
