Location & Borders

Perth is situated on the southwestern coast of Australia, in the state of Western Australia. It is nestled between the Darling Scarp to the east and the Indian Ocean to the west, with the Swan River flowing through the city. The city's location on the western coast of Australia makes it a unique and isolated urban center, with the nearest major city, Adelaide, over 2,700 kilometers away. The surrounding region is characterized by a mix of urban, suburban, and natural areas, with the nearby Darling Scarp and the Swan Coastal Plain providing a diverse range of landscapes.

The city's coastal location and proximity to the Indian Ocean have a significant impact on its climate and weather patterns.
