Ahead of the NSW state election on 25 March 2023, the NSW Government caretaker period has commenced. Limited updates will be made to this website during this period.
Weeds are a major threat to our unique natural environment, threatening the survival of hundreds of native plants and animals in NSW alone. They also impact on the price of food, human health through allergies and asthma, recreational activities and the NSW economy.
NSW WeedWise contains key information to help users reduce the impact of over 325 weeds in New South Wales.
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.
Control options are described for each weed and the herbicides registered for 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.
General, state or regional biosecurity duties under the Biosecurity Act 2015 are displayed for each weed.
NSW WeedWise can be accessed as web pages or as a smartphone app
