Australia is an island continent located in the Southern Hemisphere, so its seasons are opposite of those in Europe. It is composed of 7 territories and has a population of around 22 million people. The capital is Canberra, and the largest city is Sydney. Aboriginal Australians have lived in Australia for over 40,000 years, but now only represent 1% of the population. Some iconic Australian symbols include Uluru, kangaroos, and the Sydney Opera House.
