Noxious Weeds

• Class 1, State Prohibited Weeds,
• Class 2, Regionally Prohibited Weeds,
• Class 3, Regionally Controlled Weeds,
• Class 4, Locally Controlled Weeds,
• Class 5, Restricted Plants.

The characteristics of each class are as follows:

• Class 1 noxious weeds are plants that pose a potentially serious threat to primary production or the environment and are not present in the State or are present only to a limited extent.  "The plant must be eradicated from the land and the land must be kept free of the plant".  

• Class 2 noxious weeds are plants that pose a potentially serious threat to primary production or the environment of a region to which the order applies and are not present in the region or are present only to a limited extent.  "The plant must be eradicated from the land and the land must be kept free of the plant".

• Class 3 noxious weeds are plants that pose a serious threat to primary production or the environment of an area to which the order applies, are not widely distributed in the area and are likely to spread in the area or to another area.  "The plant must be fully and continuously suppressed and destroyed".

• Class 4 noxious weeds are plants that pose a threat to primary production, the environment or human health, are widely distributed in an area to which the order applies and are likely to spread in the area or to another area.  "The growth and spread of the plant must be controlled according to the measures specified in a management plan published by the local control authority".

• Class 5 noxious weeds are plants that are likely, by their sale or the sale of their seeds or movement within the State or an area of the State, to spread in the State or outside the State.  "Requirements in the Noxious Weeds Act 1993 for a notifiable weed must be complied with". "The plant must not be Sold, propagated or knowingly distributed".

A noxious weed that is classified as a Class 1, 2 or 5 noxious weed is referred to in this Act as a notifiable weed.  An occupier of land on which there is a notifiable weed must notify the local control authority for that land within 3 days of becoming aware that a notifiable weed is on the land.
