NSW Department of Primary Industries
The NSW Department of Primary Industries (DPI) provides support to councils and the community through Invasive Species Officers. District Agronomists are also able to provide advice on the control and management of a range of weeds including serrated tussock.
The DPI website is a great source of information on weeds. www.dpi.nsw.gov.au/agriculture/pests-weeds
