Peduncles usually 2 per axil, 4–9 mm long, rarely in short raceme (see below), somewhat stout, often patent, usually pubescent-tomentose and bracteate at base; heads globular to slightly obloid, 30–45-flowered, golden. Flowers 5-merous; sepals united. Pods linear, raised over seeds, 3–9 cm long, 2.5–3 mm wide, firmly chartaceous, glabrous; seeds longitudinal, obloid, 3–4 mm long, shiny, dark brown, aril terminal.

CVU, Gold, MuF, VRiv. Also NSW. Scattered through north-central Victoria where it grows in dry forest and mallee communities.

A population from Mt Bernard, near Avenel, is characterized by its glabrous, basally ebracteate peduncles that are sometimes arranged in very short racemes.

Similar to some variants of A. leprosa but distinguished by its glabrous, resin-ribbed branchlets, normally tomentose-pubescent peduncles (hairs dense, normally spreading, subcrisped and somewhat matted), more numerous flowers in the heads and slightly narrower pods.

Putative hybrids between A. ausfeldii and A. paradoxa have been reported.
