What's On

Biosecurity Legislation

Biosecurity Legislation for Weed Management in NSW.

Biosecurity ACT 2015

Biosecurity Regulation 2017


The financial impact of weeds on agriculture alone is approximately $2.5 billion in lost production and $1.8 billion in control activities every year. Effects on social and environmental values include a decline in native biodiversity due to competition and human health impacts such as triggering hay fever and allergies.

The biosecurity framework and tools safeguard our economy, environment and community.

The information on this page provides a brief summary of management arrangements for weed biosecurity risks in NSW.

More detailed information is available in the Biosecurity Regulation 2017, Biosecurity Order (Permitted Activities) 2017 and other documents at:

General Biosecurity Duty - What does it mean?

The outcome is to prevent, eliminate and minimise risks

  • Any land managers and users of land have a responsibility for managing weed biosecurity risks that they know about or could reasonably be expected to know about
  • Applies to all land within NSW and all waters within the limits of the State
  • Your local strategic weed management plan will provide guidance on the outcomes expected to discharge your duty for the weeds in that plan.

Control Order - What is it and what does it mean?

The outcome is to Prevent, Eliminate, Minimise or otherwise manage

Duty to notify the presence or suspected presence, certain movement controls and destruction requirements for specified plant species.


1) Visit the National Herbarium of New South Wales to see if the plant is present within NSW, at  

2) If the species is considered absent from NSW, you need to NOTIFY the Invasive Plants and Animals Enquiry Hotline on 1800 680 244 or by email to  

Mandatory Measures - What are these?


The outcome is to Prevent, Eliminate or Control the risk

  • A person cannot import into the State, or sell, any plant listed in Schedule 3 of the Biosecurity Regulation
  • A person cannot import into the State, a species of vascular plant if that species is not present in the State, unless 20 days prior notification has been provided to NSW DPI of the plant and its proposed location.
  • For example a person cannot import into the State from Queensland, certain machinery or equipment unless certain conditions are met to remove the risk of Parthenium Weed.

Biosecurity Zone - What are these and where do they apply?

The outcome is to Prevent, Eliminate, Minimise or Otherwise manage

Three zones have been established to manage high priority weeds - where a person must notify their local control authority within one working day of the presence or suspected presence of a new infestation of the weed; and take action to eradicate those weeds, or destroy as much as practicable and suppress its spread.

Alligator Weed Zone has been established for all land within the State with exception of the Greater Sydney, and parts of Hunter Local Land Services regions


Bitou Bush Zone has been established for all land within the State except land within 10 kilometres of the coast line between Cape Bryon and Point Perpendicular.


Water Hyacinth Zone has been established for all land within the State with exception of the Greater Sydney, North Coast and parts of North West, Hunter and South East Local Land Services regions.

Prohibited Matter - What is this ?

The Outcome is to Prevent entry into NSW

  • Listed in Schedule 2 of the Biosecurity Act.
  • Offence to deal with or possess prohibited matter
  • Includes Parthenium Weed, Hawkweed and Mexican Feather Grass
  • Duty to notify the presence or suspected presence
  • Duty not to test or attempt to test unless certain conditions are met
  • Authorised officer may accept a biosecurity undertaking from an owner or issue a biosecurity direction to manage a weed

How will the general biosecurity duty apply to me?

You are not expected to know about all biosecurity risks, but you are expected to know about risks associated with your industry, business, day-to-day work and hobbies.

Some measures you could take include If a weed poses a biosecurity risk in a particular area, but is not the subject of any specific legislation, the general biosecurity duty would apply to manage that weed or prevent its spread.

Property owners may fulfill their general biosecurity duty by controlling the movement of weeds on and off their land, by:

  • Finding out where products brought onto the property (such as fodder, soil, mulch or gravel) originated and taking steps to manage any risks from it
  • Holding newly acquired livestock in a restricted area before releasing them onto the property
  • Holding stock in a weed-free area before transporting them off the farm if they had been exposed to weed seed
  • Not selling feed, soil, gravel or other products that might contain weed seed
