About the guide

Prickly acacia is a Weed of National Significance. It is regarded as one of the worst weeds in Australia because of its invasiveness, potential for spread, and economic and environmental impacts.

At present over 6.6 million ha of arid and semi-arid Queensland are infested with prickly acacia, mainly in the Mitchell Grass Downs. Prickly acacia could potentially infest vast tracts of grasslands and woodlands throughout Australia.

The economic impacts of prickly acacia on Queensland's grazing industry are estimated at $5 million per year. Even at medium densities, it halves the primary productivity of grasslands, interferes with stock mustering and restricts stock access to water. Control costs considerably outweigh its benefits as a shade tree and drought fodder.

This management guide was prepared in 2003. The state and territory contacts in this document may be out of date.

For advice on weed control in your state or territory see the primary contacts on the State and territory weed control page.
