Australia's biodiversity thrives in the diverse terrestrial and marine habitats that span the country. Lush rainforests offer a refuge for countless plants and animals, while the vast dry eucalyptus woodland is home to numerous specially adapted species. Kangaroos, wallabies and platypuses are just a few of the iconic animals that call Australia home, showcasing the country's evolutionary distinctiveness. Meanwhile, the waters surrounding the country support some of the most spectacular marine biodiversity on the planet. Vibrant coral reefs, seagrass meadows and rocky shorelines contribute to the country's rich marine tapestry. This is a unique world filled with stunning natural beauty, inhabited by some of the most extraordinary and deadly animals on the planet.
