Local Government NSW (LGNSW) provides support and advocacy on behalf of member councils on biosecurity issues, including weeds and pests.

Weeds and pests threaten valuable agricultural industries, reduce the economic viability of communities, affect human health, and pose a major threat to our unique biodiversity. Weeds alone cost NSW $600 million and Australia $4 billion every year in lost production and control measures.


Biosecurity is the protection of the economy, environment and community from negative impacts associated with pests, diseases and weeds. The NSW Biosecurity Strategy (2013-2021) introduced the principle of shared responsibility for biosecurity.

The Biosecurity Act 2015 establishes a general biosecurity duty to make sure responsibility for biosecurity risk is shared among government, industry and the community. This means if you deal with biosecurity matter or are a carrier, you need to identify the risks it may pose and act to manage or mitigate the risk.

Weeds management

Noxious weed management has been the responsibility of local government in NSW for over 100 years, most recently under the Noxious Weeds Act 1993. With the commencement of the Biosecurity Act 2015, the Noxious Weeds Act (and 13 other pieces of legislation) was repealed. However, local control authorities (often councils) have specific responsibilities for the regulation of weeds. Councils can fulfil these responsibilities either individually or as a collective to harness resources and capabilities.

Local Land Services are responsible for coordinating Regional Weeds Committees in each region. These committees are made up of local control authorities, public and private landholders, and community members. Each Regional Weeds Committee has developed a five-year Regional Strategic Weed Management Plan to focus on managing weed biosecurity.

Pest Management

Local Land Services also has responsibility for coordinating Regional Pest Animal Committees, which have prepared five-year Regional Strategic Pest Management Plans.
