Noxious Weeds of the Illawarra

The plants shown in the following table are declared noxious throughout the local government areas of Kiama, Shellharbour City and Wollongong City. For more detailed information click on the name of the weed you are interested in. There are a small number of weeds which are listed throughout NSW as noxious in Class 1 or 5 for which no information is presented on this website. These are generally either rare or not yet present in NSW, or in some cases Australia. If you want more information about these species an Australian or world-wide Google search on the scientific name will usually provide information. It is better to use the scientific name because it is constant throughout the world, while common names vary from place to place.
