Australia is a capitalist country with the capital of Canberra. As the most economically developed country in the southern hemisphere, the world's 12th largest economy, and the world's fourth-largest exporter of agricultural products, it is also the world's largest exporter of various minerals, so it is called "a country setting on a minecart." At the same time, Australia is also the country that raises the number of sheep and exports the most wool in the world, and is also known as the "country on the back of sheep." Australia's population is highly urbanized, with nearly half of its citizens living in the two major cities of Sydney and Melbourne. It is also a sports power, hosting many sports events around the world throughout the year. Australia actively participates in international affairs. It is a founding member of APEC and a member of the United Nations, the G20, the Commonwealth, the Organization for Economic Cooperation and Development, and the Pacific Islands Forum.
