Allocasuarina fibrosa is a dioecious shrub that typically grows to a height of 0.5–1.5 m (1 ft 8 in – 4 ft 11 in). Its branchlets are 20–50 mm (0.79–1.97 in) long, the leaves reduced to erect, scale-like teeth 1.5–2.0 mm (0.059–0.079 in) long, arranged in whorls of four around the branchlets. The sections of branchlet between the leaf whorls (the "articles") are 8–16 mm (0.31–0.63 in) long. Male flowers are arranged in spikes 4–7 mm (0.16–0.28 in) long, the anthers 0.5–0.6 mm (0.020–0.024 in) long. Female cones are more or less cylindrical to spherical and covered with hairs, mature cones 11–25 mm (0.43–0.98 in) long and 9–11 mm (0.35–0.43 in) in diameter, often with awn-like projections up to 2 mm (0.079 in) long. The samaras brown to black and 6–7 mm (0.24–0.28 in) long. Flowering occurs in July and August. This sheoak is similar to Allocasuarina grevilleoides.

This species was first formally described in 1928 by Charles Gardner who gave it the name Casuarina fibrosa in the Journal of the Royal Society of Western Australia, from specimens he collected near Tammin in 1926. It was reclassified in 1982 as Allocasuarina fibrosa by Lawrie Johnson in the Journal of the Adelaide Botanic Gardens. The specific epithet (fibrosa) refers to the long fibres on the cones.
