Shrub or tree 1.5–10 m high; branches sometimes pendulous. Bark corky, furrowed. (1)

Often occurs as a scattered understorey tree in grassy, open eucalypt woodland, as well as growing in open forest, Acacia woodland or sometimes shrubland, in clay, loam, sandy or stony soils, on plains or on valley floors, slopes and ridges in undulating to hilly country, also in skeletal soils on rocky slopes. Flowers mainly Nov. and Dec., sometimes Apr.–Oct., also sporadic; fruits (Dec.–) Apr.–Oct. (1)

Previously known as Acacia bidwillii. Inflorescences are globular. Seed is available later than the majority of Acacias in Queensland, more specifically around February to April rather than from September to December. We often see Vachellia bidwillii regenerating on country extensively cleared for grazing across central and southern Queensland. This country is often undulating and constituted of basaltic soils supporting woodland remnants of Corymbia erythrophloia, Eucalyptus melanophloia, Eucalyptus populnea and Corymbia tesellaris and Eucalyptus tereticornis around drainage areas.

The roots of young trees were roasted and eaten by Aborigines, and young plants may be browsed by cattle, fide E.Anderson, Pl. Central Queensland 22 (1993). (1)
