Noxious Weeds are declared by an "order" under the Noxious Weeds Act 1993 (NWA). Weeds may be declared over the entire state or in one or more Local Government Area (LGA). The Local Control Authority (LCA) for land within a LGA is the council of the LGA or the County Council or the Noxious Weeds Authority.
For a complete list go to www.dpi.nsw.gov.au/noxweed and choose your LCA.
Both environmental and production weeds may be declared under the NWA and all land managers are responsible for controlling Noxious Weeds as specified by the below weed control classes.
Class 1, State Prohibited Weeds, must be eradicated from the land and the land must be kept free of the plant *
Class 2, Regionally Prohibited Weeds, must be eradicated from the land and the land must be kept free of the plant *
Class 3, Regionally Controlled Weeds, must be fully and continuously suppressed and destroyed and where applicable the plant must not be sold, propagated or knowingly distributed
