Isolated from the rest of the world for millions of years, Australia's wildlife is nothing short of sensational. From the arid desert of Australia's red centre to the snow-covered peaks of the Alps, from the riches waiting to be discovered in the waters of Western Australia's shark coast to the lush jungles of the Daintree on the opposite side of this vast continent, and to the isolated rarities found only in Tasmania, Australia's national parks are home to some of the world's greatest treasures.
