Two collections of Amyema pendulum, drooping mistletoe have been made on Acacia dealbata. This mistletoe is more commonly found on species of Eucalyptus.

The fixation of nitrogen by A. dealbata seedlings was studied by Hopmans et al. (1983). Activity was markedly affected by soil moisture and was significantly reduced at wilting point. It was also reduced after long dark periods but only when this exceeded 12-15 hours. The addition of nitrogen fertiliser caused a rapid decline of nitrogen fixation. Increasing soil salinity also reduced activity though A. dealbata is not normally a species found in sub-saline areas.

A. dealbata was included in Forest Trees of Australia, Boland et al. (1984) where a description, illustrations and a map are given.

A. dealbata is now naturalised in New Zealand, Webb et al. (1988), and has become well-established in South Africa, Ross (1975) as well as southern Europe.

Henderson (1989) has shown that A. dealbata is one of the most prominent woody invasive aliens in the grassland biome of Orange Free State.

A. dealbata is the 'Mimosa' of southern Europe where it was early introduced and is grown for florists use. The timber is of poorer quality than many other Acacia but has been used for glued products, clothes pegs, pulping and woodwool.

In southern France A. dealbata is one of several species of Acacia to provide not only cut flowers but also a source of aromatic oils for perfumery, Poucher (1984).

Payne (1989) described the cultivar A. dealbata cultivar Kambah Carpet a prostrate form growing to 20 cm high and 3 m across. It was first recognised in Canberra in 1982 and has to be propagated by cuttings or suckers.

Wool may be dyed with A. dealbata leaves to yellow-fawn or green depending on the mordant used, Martin (1974).
