The main objective of the Noxious Weeds Act 1993 is to prevent the spread of noxious weeds. Cootamundra-Gundagai Regional Council (CGRC) has a ranger to manage and control Council’s noxious weeds operations and to establish strategies and statements to control noxious weeds in accordance with the Noxious Weeds Act 1993 within the Council region.

Weeds are declared noxious according to the extent of the weed, available control methods and the weed’s importance. Noxious weeds have potential to become widespread and cause harm to agriculture, human health and the environment.

Weed spraying in townships are conducted after a formal advertising in the local newspapers of such activities.  Roadside weeds spraying outside of township is exempt though Council maintains a program by its inspector.

The ranger is also responsible for informing Council of any breaches of the Noxious Weeds Act by individual landowners.

Latest News
The NSW State Government has made some changes to the Noxious Weeds Act.

For the Cootamundra-Gundagai Region, these changes include:

  1. A change in the definition of a Class 4 Noxious Weed, which now reads

“The growth of the plant must be managed in such a manner that reduces its numbers spread and incidence and continuously inhibits its reproduction (and the plant must not be sold, propagated or knowingly distributed).

  1. Class 4 Weed Management Plans are now to be used as a guideline for land owners on controlling these noxious weeds.
  1. Additions to the Noxious Weeds list include:

Class 1 – Heteranthera, Hydrocotyle and Kosters curse
Class 2 – Black willow, Boneseed, Cape broom, Mesquite, Parkinsonia
Class 4 – East Indian Hygophilia – (changed from Class 1)

  1. An updated list of non-saleable weeds is also available from Council and will be distributed to retail outlets.

Council has received advice from the Department of Primary Industries that Tropical soda apple (Solanum viarum) has been declared a Class 2 Noxious Weed across the Riverina. This C2 classification means the plant must be eradicated from the land and the land must be kept free of the plant. As Tropical soda apple is found on properties located on the North Coast of NSW, farmers who have had any cattle come in from this area should check their stock yards and holding paddocks for the weed and seek advice on its eradication.

Cootamundra-Gundagai Regional Council is a member of both Eastern Riverina Noxious Weeds Advisory Group (ERNWAG) and Lachlan Valley Noxious Weeds Advisory Committee LVNWAC) are the leading committees for weed management in the Riverina region including the catchments of the Murray, Murrumbidgee, Lower Murray Darling and Lachlan.



FIREWEED (Senecio madagascariensis)
The Cootamundra-Gundagai Regional Council is joining with other Councils to make Fireweed as a Class 3 Noxious Weed in the eastern Riverina region.

Fireweed is a highly invasive and opportunistic weed which quickly colonises overgrazed pastures and disturbed areas.

Fireweed is a serious pasture weed of coastal New South Wales and is now invading inland areas, including the South West Slopes.

Regionally, Fireweed has been found in the Gundagai, Wagga and Yass areas, often along the Hume Highway.

Fireweed is a daisy-like plant that grows from 10 to 60 cm high. It has a variable growth habit and leaf structure, but the most common form of fireweed is a low, heavily branched, annual or short lived perennial plant.

Generally bright green in colour, fleshy and narrow, leaves are 2-7 cm long, alternately arranged on the stem, and have serrated, entire or lobed margins. Broader leaves usually clasp around the stem.

Small, yellow and daisy-like, flowers are 1-2 cm in diameter and arranged in clusters at the end of each branch. They can number from 0 to 200 per plant, and each flower will commonly have 13 petals and 21 bracts forming the ‘cup’ under the flower.

Fireweed has a shallow, branched taproot with numerous fibrous roots growing from 10 to 20 cm deep.
