Usage

In J.W. Turnbull (ed.), Multipurpose Australian Trees and Shrubs 112–113 (1986), there is an account of V. bidwillii (as Acacia bidwillii) before it was split into several species, while a more recent brief account is given in J.C. Doran & J.W. Turnbull (eds), Australian Trees and Shrubs: Species for Land Rehabilitation and Farm Planting in the Tropics 346 (1997). Young plants may be browsed by cattle, fide E. Anderson, Plants of Central Queensland 22 (1993).
