There are more than 350[citation needed] suburbs in the Perth metropolitan region (colloquially known as Perth, the capital city of Western Australia) as of 2021.
[update] The name and boundary of a locality (commonly referred to as a suburb in the metropolitan region[according to whom?])
is determined under the authority of the Minister of Lands in Western Australia, and form an official component of addresses.
[1][definition needed] Some of the suburbs are contained within two or three local government areas – these have been marked and cross-referenced.
