Numerous marine introductions into Australian waters have occurred and will continue to occur. The mechanisms by which they occurred and the difficulties of eradication once they have become established are discussed. Introduced species are often categorised as being either a pest or cryptogenic and the criteria used to distinguish between these categories is discussed, although they may not be mutually exclusive. The main concern is that, for most species, we lack information as to the impact which they are having on native species and their associated marine communities. Finally, the difficulty in determining the native range of a species and the taxonomic difficulties of deciding if a species represents a new invasion, or just a natural range extension is commented on.
