NEWA Control Program

The Biosecurity Act 2015 came into effect on 1 July 2017 and replaces all or part of 14 Acts including the Noxious Weed Act 1993.

The regulations, instruments, policies and procedures that underpin the Biosecurity Act 2015 have been developed in consultation with industry, community and government partners to ensure the development of a regulatory framework that will effectively respond to and manage biosecurity risks.

Central to the control of invasive plants is the enforceable concept of General Biosecurity Duty. This means any person dealing with plant matter must take measures to prevent, minimize or eliminate the biosecurity risk (as far as practicable). Further background information on General Biosecurity Duty and the other regulatory instruments of the Act can be found in the Northern Tablelands Regional Strategic Weed Management Plan 2017-2022 and at NSW DPI Weedwise
