From Wikipedia:
Although most of Australia is semi-arid or desert, it covers a diverse range of habitats, from alpine heaths to tropical rainforests. Because of the great age and consequent low levels of fertility of the continent, its extremely variable weather patterns, and its long-term geographic isolation, much of Australia's biota is unique and diverse. About 85% of flowering plants, 84% of mammals, more than 45% of birds, and 89% of in-shore, temperate-zone fish are endemic.[14] Many of Australia's ecoregions, and the species within those regions, are threatened by human activities and introduced plant and animal species. The federal Environment Protection and Biodiversity Conservation Act 1999 is a legal framework used for the protection of threatened species. Numerous protected areas have been created under the country's Biodiversity Action Plan to protect and preserve Australia's unique ecosystems, 64 wetlands are registered under the Ramsar Convention, and 16 World Heritage Sites have been established. Australia was ranked thirteenth in the World on the 2005 Environmental Sustainability Index.
Most Australian woody plant species are evergreen and many are adapted to fire and drought, including many eucalyptus and acacias. Australia has a rich variety of endemic legume species that thrive in nutrient-poor soils because of their symbiosis with Rhizobia bacteria and mycorrhizal fungi. Well-known Australian fauna include monotremes (the platypus and echidna); a host of marsupials, including the kangaroo, koala, wombat; and birds such as the emu, and kookaburra. The dingo was introduced by Austronesian people that traded with Indigenous Australians around 4000 BCE. Many plant and animal species became extinct soon after human settlement, including the Australian megafauna; others have become extinct since European settlement, among them the Thylacine.
Kangaroos, wombats, koalas, tazmanian devils, emus, the platypus, echidna, plus a whole host of poisonous snakes, scorpions, tarantulas, the ability to have a Great Barrier Reef Exhibit, the famous New Zealand kiwi bird. Tons of species throughout Australia and New Zealand are endangered with many many many species having gone extinct in recent years. Sounds like a perfect match to Disney's message of conservation. Australia is also home to incredibly diverse ecosystems from the reefs to the outback to temperate mountains and tropical rainforests. Suggesting that the place where Steve Irwin got his start is home to demure animals is a bit much...some of the most dangerous animals in the world come from Australia.
