A perennial, tufted grass native to south-eastern Australia, Rytidosperma caespitosum forms dense, low-growing tussocks with fine, arching leaves and slender flowering stems. It thrives in grasslands, open woodlands, and well-drained soils, preferring full sun.
 
Common Wallaby Grass is valued in revegetation projects and native gardens for its drought tolerance, soil-stabilising roots, and ability to provide habitat and food for native fauna, making it an important species for maintaining biodiversity.
