About
Including the Central Business District of Greater Perth, and stretching north of the Swan River and west to the Indian Ocean, Perth - Inner consists of :
The City of Perth, The City of Vincent, parts of the Cities of Bayswater and Stirling, The Town of Cambridge, The City of Subiaco, The City of Nedlands, The Town of Claremont, The Town of Cottesloe, The Shire of Peppermint Grove and the Town of Mosman Park.
The radial Perth commuter rail network is centred on Perth Railway station (and the Perth Underground Railway station), and major highways such as the Graham Farmer Freeway, Stirling Highway and Mitchell Freeway pass through the region.
Unlike the other metropolitan Perth SA4s, the Perth-Inner region includes mainly of more densely populated inner city suburbs and established middle ring suburbs with no greenfield development. Significant redevelopment plans are in place for East Perth and Subiaco, and densification is being directed across the major arterial routes of the SA4.
This SA4 region is home many of the key government, commercial and recreation sites of the State, including the State Parliament and Supreme Court, headquarters of large companies, the WACA and Kings Park.
