Australia is one of the most important nations on Earth for biodiversity. In fact, it 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 per cent of our mammal species, 93 per cent of reptiles, 94 per cent of frogs and 45 per cent of our bird species are found only in Australia.
