Noxious weeds

A noxious weed is any plant that is declared noxious under the Noxious Weeds Act 1993. To be declared, a weed must have a detrimental effect on, or cause serious economic loss to, agriculture or the environment. A weed will only be declared noxious if there are reasonable and enforceable means of controlling it.

Weeds may be declared noxious on a Council-area basis or on a part or whole state basis. Weeds may be declared or deleted from declaration, and weed categories may change from time to time.

Randwick City Council is the Local Control Authority for implementing the Noxious Weeds Act 1993.
