There is no such thing as an Australian introduced species in the Murray River. If it is Australian, it is not introduced. Species which have been introduced from overseas include various species of Carp, Brown and Rainbow trout, Redfin perch and Gambusia. The most prolific of these is the carp.
Paddlesteamers were first introduced along the Murray River in Australia.Australia's first paddlesteamer, the 'Lady Augusta', was first launched from Goolwa by Francis Cadell in 1853.

In the first place, introduced species threaten the food supplies of native animals. Introduced species tend to breed more quickly than native species, so they eat more, often razing feeding grounds which would support native herbivores for months by eating vegetation right down to the roots. Secondly, many introduced species are predators, and native Australian animals have not developed effective defence adaptations against predators that are new to them. Introduced plant species tend to spread more quickly through native habitats, killing off native plant species which might provide the natural food of Australian animals.
