Shrub or tree to 5 m high, spreading. Bark furrowed, usually grey or brown. Branchlets terete except at apices, grey or brownish, slightly scurfy, glabrous. Phyllodes narrowly elliptic to very narrowly elliptic, sometimes ±oblanceolate to narrowly oblanceolate, flat, straight or very slightly curved, 3–7.5 (–9) cm long, 4–15 (–25) mm wide, with obtuse and often mucronulate apices, coriaceous, grey- or blue-green, glabrous, resinous when young, very finely multistriate, non-anastomosing, sometimes with 1–3 nerves slightly more prominent; gland ±basal. Peduncles 5–12 mm long, glabrous. Spikes 1 or 2 per upper axil, 1–2.5 cm long, dense, bright golden. Flowers 5-merous; calyx cupular, dissected to 1/3, hairy mostly at base; corolla 1.3–2 mm long, 2–2.5 times as long as calyx. Pods oblong to narrowly oblong, flat, 2–7 cm long, 1–1.6 (–2) cm wide, chartaceous, finely transversely reticulate, glabrous, often slightly resinous. Seeds transverse to slightly oblique. Fig. 60D–I.
Occurs in all mainland States except Vic. and N.S.W. Widely distributed in arid areas, where it occurs usually on stony hillsides or in coarse textured alluvial soils; often abundant in mulga woodlands on red sandy loam plains. Probably flowers whenever temperature and soil moisture are high. Fruiting mainly Aug.–Nov. Map 394.

It is closely allied to A. stowardii and A. duriuscula . Also related to A. aprepta .
Aborigines obtained witchetty grubs from the roots, as well as the bush providing edible gum and seed (A.Urban, Wildflowers & Pl. Centr. Australia 84, 1990). Details on fire tolerance and Aboriginal use of A. kempeana are given by P.Latz, Bushfires & Bushtucker 102 (1995).
Since publication of the Flora of Australia the Australian Plant Census recognises Acacia sibirica (placed in synonymy in the Flora of Australia ) as an accepted species. Acacia kempeana remains as an accepted name.
