Weeds of National Significance (WoNS)

Under the Australian Weeds Strategy, 32 WoNS have been identified by Australian governments based on their:

  • invasiveness
  • potential for spread
  • environmental, social and economic impacts.

A list of 20 WoNS was endorsed in 1999 and a further 12 were added in 2012.

Note that some of the 32 WoNS are grouped together together as one (e.g. Asparagus weeds, Brooms, Opuntioid cacti, and Bitou bush/Boneseed).

Most WoNS have species-specific management manuals and guides. Click through for these resources on the weed profile where you will also find distribution maps, image gallery and references and related links.
