The NSW WeedWise app provides key information to help users reduce the impact of weeds in New South Wales (NSW). The app profiles over 300 weeds, describing biosecurity duties under the NSW Biosecurity Act 2015, control information and registered herbicide options. 

Users, ranging from home gardeners and residents to farmers, land managers and weeds professionals, can search or browse weed names (common or scientific); recognise a weed by its physical description and image gallery; and find out about its impacts, where it occurs, how it spreads and its preferred habitat. 

It is important to understand the biosecurity duties associated with plants that pose weed risks in NSW and users can view the state and regional priorities for each weed under the NSW Biosecurity Act 2015, listed by Local Land Services regions.  

Control options are described for each weed and the herbicides registered for its control by the Australian Pesticide and Veterinary Medicines Authority are listed, including application rates and techniques, and any minor-use permits that must be complied with.  

Features include: 
User type - users experience different functions within the app depending on whether they are landholders/residents or weeds professionals. 

Landholders/residents can enter the contact details of their local council weeds officer, and then directly report sightings of state priority weeds via email or SMS. 

Weeds professionals can share information about a weed with clients via email or SMS, including a weed's profile, biosecurity duties, control advice and herbicide options.

NSW WeedWise incorporates the content contained in the Noxious & Environmental Weed Control Handbook, a free, biennial publication from NSW Department of Primary Industries.

NSW WeedWise was developed with the assistance of the NSW Weeds Action Program.​
