Due to its geographical situation and isolation Australia has distinct fish fauna, including many endemic species. From the 18th century, early colonisers began introducing a number of exotic species including mammals, plant, birds and fish. The introduction of the fish has led to serious ecological damage, most notable being the effect of common carp in the Murray-Darling Basin. Introduced carp now dominate the freshwater systems of southern Australia. While the damaging impact of carp is well recognised, little in the way of control measures have been employed to control their spread. Their ability to colonise almost any body of water, even those previously considered to be beyond their physical tolerances, is now well established. Control of exotic fish species is being undertaken by various government departments, though many problems are faced.

The marine waters of the Houtman Abrolhos, an island chain off the coast of Western Australia, are unusual in containing a mix of tropical, subtropical and warm-temperate fish species. This mix is largely due to the Leeuwin Current, which brings warm tropical water to the Houtman Abrolhos, especially in winter. Tropical species are the most abundant, eleven of the sixteen most abundant species being tropical fishes. However, there are also a large number of tropical species with populations so small that they are thought not to maintain populations be breeding at the Houtman Abrolhos.
