Native water rats

The native water rat (Hydromys chrysogaster) grows to 40 centimetres in length. It has partially webbed hind feet, water-repellent fur and a tail that is tipped white. The species is one of only two Australian mammals living in freshwater, the other being the platypus.

Their diet consists primarily of crustaceans (animals such as crabs, lobsters, crayfish, shrimps, prawns, krill, woodlice, and barnacles), insects and fish. Occasionally, they also feast on small birds, frogs, spiders and reptiles.

Grassy foreshore vegetation surrounding the Robina Lakes has the potential to provide suitable habitat and conditions for the species.

In terms of controlling or removing the Native Water Rat from the lakes, it should be noted that they are a native species and are protected under the Nature Conservation Act 1992. Under this legislation, it is a requirement to conserve native wildlife and to identify and conserve their habitats.
