Australia is a vast and sparsely populated land with diverse geography, including rainforests and deserts, and is home to unique species such as kangaroos and koalas. The Aboriginal people have inhabited Australia for over 40,000 years, maintaining a deep connection to the land and its history through art and music. Despite its harsh environment, Australia has a rich biodiversity, particularly in coastal areas like the Great Barrier Reef, and its society is a blend of various cultures, with a significant urban population concentrated mainly in coastal regions.
