What's On

Biosecurity - Weeds Management

What are weeds?

The definition of a WEED is a plant that is growing in the wrong place at the wrong time.

Some plants require specified management control actions and obligations under relevant legislation due to their detrimental impact on human health, agriculture and/or our environment.

Why should we manage weeds?


  • Negative effects on social and environmental values including a decline in native biodiversity due to competition and human health impacts
  • There are weeds that are poisonous or harmful to livestock and to people.
  • Some weeds cause dermatitis, skin inflammations, health problems, asthma, hay fever and poisoning.
  • Others can decrease the quality of water making it unsuitable to drink.
  • Some water weeds impede the flow of water along creeks, rivers, watercourses and drainage channels.
  • Weeds can also cause tainting of milk, meat, eggs and other products.
  • Plus they can rapidly invade natural bushland and reduce the density and variety of native plant species.

The Noxious Weed Act 1993  has been replaced by the Biosecurity Act 2015, which came into force as of 1 July 2017.

For further information please refer to the Biosecurity page or contact NSW Department of Primary Industry. 

Biosecurity: A Shared Responsibility

Government industry and the people of NSW working together to protect the economy, environment and community from the negative impacts of animal and plant pests and diseases, weeds and contaminants for the benefit of all people in NSW.    

Why do we need to manage weeds?

Weeds can be found anywhere and everywhere, from a farmer's paddock to your own flower garden at home.

No matter what the situation or the person, weeds are seen as a pest and/or a problem and they can prove to be very costly.

How much do weeds cost Australia per year?

The financial impact on agriculture alone is approximately $2.5 billion in lost production and $1.8 billion in control activities every year.  This does not include the cost of the decline in native biodiversity and natural environment. It also does not include the cost of our unsung volunteer groups such as: Landcare, Greening Australia and other volunteer conservation groups.

What is Councils role in Biosecurity management?

Council’s Weeds Biosecurity Unit, manage and provide effective services of weed management within the Local Government Area to ensure compliance with all relevant Acts, Regulations and Standards.

The Weeds Biosecurity Unit provides a number of services including:

  • Weed identification, management and eradication.
  • Safe storage, transport and handling of pesticides within Council.
  • Weed control on Council land and vacant Crown Land.
  • Property inspections including: private, business and commercial and other government departments.
