Cabomba (Cabomba caroliniana) is an introduced perennial, native to America, which has now naturalised in Australia. It is a State-declared category 3 pest plant species, and has a Weeds of National Significance (WONS) status which means the species is already spread over substantial areas of Queensland, but its impact is so serious that it requires active control to avoid further spread onto properties that are still free of the pest (Department of Employment, Economic Development and Innovation, 2011).

The species has the potential to obstruct water flow and dominates nutrient-rich freshwater lakes such as Robina Lakes. The species has little value to wildlife. Control is very difficult and shows some resistance to herbicides (Sainty and Jacobs, 2003).

Management of Cabomba has previously relied on mechanical removal. Recently, a new herbicide has been registered for use on Cabomba. City of Gold Coast is investigating the use of this herbicide to reduce the spread of this pest plant by reducing density around boat ramps.
