Perth is the capital and largest city of Western Australia, with a population of approximately 2,098,239 inhabitants. Situated on the southwest coast of Australia along the Swan River and the Indian Ocean, Perth is one of the most geographically isolated major cities in the world. Founded in 1829 as part of the Swan River Colony, the city developed through maritime trade, gold rush wealth in the late nineteenth century, and later mining and energy industries.

Perth is known for its Mediterranean climate, extensive parklands, and coastal scenery. Prominent landmarks include Cottesloe Beach, a popular destination for swimming and surfing, and the historic port city of Fremantle, noted for its preserved colonial architecture. Cultural institutions, universities, and festivals contribute to the city’s role as a regional hub. Notable individuals born in Perth include actor Heath Ledger and professional footballer Samantha Kerr.
