Australia is one of the most important nations on Earth for biodiversity. In fact, Australia is one of only 17 “megadiverse” nations and is home to more species than any other developed country. Most of Australia’s wildlife is found nowhere else in the world, making its conservation even more important. 87% of our mammal species, 93% of reptiles, 94% of frogs and 45% of our bird species are found only in Australia.
