List of Australian butterflies

Australia has more than 400 species of butterfly, the majority of which are continental species, and more than a dozen endemic species from remote islands administered by various Australian territorial governments. The largest butterflies in the world are endemic to the Australasian ecozone. They are the birdwings—Ornithoptera and other genera—of the Troidini tribe of swallowtail butterflies (Papilionidae).

Australia has 8,222 islands within her maritime borders. This is small in comparison with her northern neighbour Indonesia, with about 18,300 islands (high geological activity is constantly adding and removing Indonesian islands). The British Isles include more than 6,000 islands over a much smaller area. The Greek islands include about as many islands depending on the minimum size to take into account, but in an even smaller area.
