Noxious weeds

bioThe Noxious Weed Act provides the regulatory framework for controlling weeds in NSW. The Act requires all land occupiers to notify and control noxious weeds on their land, Local Control Authorities are established to manage weed control programs, and noxious weed inspectors and officers are given authority to enforce the Act.

Control classes of noxious weeds

There are five classes of Noxious Weeds that each require a certain treatment and management strategy.

Class 1= State Prohibited Weeds. The plant must be eradicated from the land and the land must be kept free of the plant. Control Objective: to prevent the introduction and establishment of those plants in NSW

Class 2 = Regionally Prohibited Weeds. The plant must be eradicated from the land and the land must be kept free of the plant. Control Objective: to prevent the introduction and establishment of those plants in parts of NSW.

Class 3 = Regionally Controlled Weeds. The plant must be fully and continuously suppressed and destroyed. Control Objective: to reduce the area and the impact of those plants in parts of NSW.

Class 4 = Locally Controlled Weeds. The growth of the plant must be managed in a manner that reduces its numbers spread and incidence and continuously inhibits its flowering and reproduction

Class 5 = Restricted Plants. The requirements in the Noxious Weeds Act 1993 for a notifiable weed must be complied with.A noxious weed that is classified as a Class 1, 2 or 5 is referred to in the NWA 1993 as a notifiable weed. This means, inter alia, that the LCA (Council) must be notified of the presence of such weeds within three (3) days of their detection. Control Objective: to prevent the introduction of those plants into NSW, the spread of those plants within NSW or from NSW to another jurisdiction.
