Australia, a vast continent-country in the Southern Hemisphere, is known for its unique wildlife, stunning landscapes ranging from the outback to the Great Barrier Reef, and a vibrant, multicultural society. Its economy is one of the world's largest, driven by mining, agriculture, and tourism. Cities like Sydney, with its iconic Opera House, and Melbourne, renowned for its cultural scene, contrast with the country's vast, sparsely populated interior. Australia has a strong tradition of sports, particularly cricket, rugby, and Australian Rules Football.
