Welcome to the Illawarra District Weeds Authority (IDWA) website.

This website has been designed to provide a guide to the identification and control of Priority weeds within the Illawarra region of southern New South Wales.

The Illawarra District Weeds Authority has been serving the Illawarra community since 1993. Our purpose is to administer the Biosecurity Act 2015 and control priority weeds within the three local government areas of Wollongong City, Shellharbour City and Kiama Municipal Council.
