Slender, sparingly branched shrub, usually 1–3 m high; branchlets acutely angled to flat, glabrous, sometimes pruinose. Phyllodes ascending to erect, narrowly linear to linear-oblanceolate or very narrowly elliptic, usually 7–12(–16) cm long and 3–8 mm wide, frequently slightly curved, thin to moderately coriaceous, glabrous, narrowed at base, mucronate; midrib prominent, lateral veins absent or obscure; glands not prominent, one 0–2 mm above pulvinus, usually another at base of mucro. Racemes with rachis 1–2.5 cm long, 6–12-headed, enclosed when young by conspicuous, imbricate bracts; peduncles 3–5 mm long, slender, glabrous; heads globular, 3–10-flowered, pale cream to lemon-yellow; bracteoles absent. Flowers 5(–4)-merous; sepals free, narrowly linear. Pods oblong, 2–5 cm long, 1–2 cm wide, thinly coriaceous-crustaceous, glabrous, purplish-brown to blue-black, pruinose; seeds transverse, elliptic, 6–7 mm long, shiny, black, aril brown-black. Flowers Apr.–Oct.

Similar to the South Australian species (naturalised in Victoria) A. iteaphylla which has a different habit, branchlets angled only at the extremities, heads with more flowers, peduncles longer, and pods longer, usually broader and with longitudinal seeds.

Morrison & Rupp (1995) recently erected 5 subspecies of Acacia suaveolens. Of these, 2 are reported from Victoria: the widespread subsp. suaveolensand the geographically restricted subsp. grampianensisMorrison & Rupp. However, due to the substantial overlap and uncertainty of the diagnostic features, these new taxa are of doubtful utility and not recognized here.
