Marsupials are animals such as koalas and wombats.The kangaroo is perhaps the best known of the marsupials. Besides the marsupial, the strange animals of the continent include emu and the duckbill platypus. There are many physical feature of Australia that also are unique, including the central part of the country known as "Outback" , which consists off three main deserts. More than half of all Australians live in large, morden cities along the coast. There are so many people living in the small towns on the edge of the Outback, where there is plenty of grassfor raising sheep and cattle. Autralia rates first in the world for sheep raising. In fact, there are more than 10 times as many sheep in Australia as there are people!
