Which city is the state capital of Western Australia?

Perth is the state capital of Western Australia and is located on the southwestern coast of the continent, along the banks of the Swan River. As the capital city, Perth functions as the political, economic, and cultural center of the state. It is known for its vibrant cultural scene, extensive parklands, beautiful beaches, and as a hub for the mining and resources sectors, which are significant for the state's economy.

Western Australia's position and geographic characteristics, including its significant urban population and development, solidify Perth's role as the capital. The other cities mentioned—Adelaide, Hobart, and Darwin—are capitals of their respective states (South Australia, Tasmania, and the Northern Territory), but do not hold the title for Western Australia. Thus, the correct identification of Perth as the capital highlights not only its importance to the state but also its distinct place within Australia's geographic landscape.
