What is a noxious weed?


What is a noxious weed?

A noxious weed is a plant that poses a threat to agriculture, the environment or the community, and has the potential to spread to other areas. It has been declared, by order of the Minister published in the Gazette, to be a noxious weed for the purposes of the Noxious Weeds Act, 1993.

Other weeds, known as environmental weeds, are plants that aggressively invade native bushland outside their normal geographic range, and displace native flora and fauna.

How does Council deal with noxious weeds?

Noxious weeds in parks and streets are controlled by means of the application super-heated steam. This work is carried out on a regular cycle by contractors.

Weeds in bushland areas are controlled by community volunteers and Council’s bushcare crew using standard bush regeneration methods. This mostly involves hand weeding, planting native groundcovers and grasses, and the application of mulch. 

For further information on weeds in bushland areas contact Council’s Biodiversity Officer at

There are weeds growing in my street that require treatment. When will Council remove them?

If the weeds are in a street which has grass verges, the weeds will be removed as part of the regular street cleaning crew’s 20 day maintenance cycle. If the street does not have grass verge, the weeding is carried out by Council’s weed contractor using steam treatment.

If you provide Council with the details, Council’s Parks & Streetscape Coordinator will arrange for the works and will contact you to let you know when this will be done. Contact Council's Customer Services on 93679222.

Where streets are treated by Council’s weed contractor, this system uses super heated hot water to control the weeds. This works by destroying the cells of the plant and is carried out 8 times per year. Council will have our contractor contact you to tell you when they are next going to carry out this treatment in your street.

What if noxious weeds are on private property?

If the weeds are on private property, Council’s Compliance Section will inspect and issue an order under the Noxious Weeds Act for the property owner to control and remove this weed from their property.

If you provide the location of these weeds, a compliance officer will contact you to let you know what can be done. Contact Council's Customer Services on 93679222.

Under the Noxious Weeds Act, Council can, as the regulatory authority, issue orders to the property owner to clear, control or suppress the growth of weeds dependent on their classification.

Noxious Weeds Act, 1993

The Noxious Weeds Act 1993 states that occupiers of land have a responsibility for controlling noxious weeds on the land they occupy. The Act applies to a plant declared, by order of the Minister published in the Gazette, to be a noxious weed for the purposes of this Act.

The objects of this Act are to:

  • identify noxious weeds in respect of which particular control measures need to be taken
  • specify those control measures
  • specify the duties of public and private landholders as to the control of those noxious weeds 
  • provide a framework for the State-wide control of those noxious weeds by the Minister and local control authorities
