Perth

Perth (Nyungar: Boorloo) is the capital city of Western Australia. It is the fourth-most-populous city in Australia, with a population of over 2.3 million within Greater Perth as of 2023^[update]. The world's most isolated major city by certain criteria, Perth is part of the South West Land Division of Western Australia, with most of Perth's metropolitan area on the Swan Coastal Plain between the Indian Ocean and the Darling Scarp. The city has expanded outward from the original British settlements on the Swan River, upon which its central business district and port of Fremantle are situated.

Perth was founded by Captain James Stirling in 1829 as the administrative centre of the Swan River Colony. The city is situated on the traditional lands of the Whadjuk Noongar people, where Aboriginal Australians have lived for at least 48,000 years. Perth was named after the city of Perth in Scotland. Initially established as a free settlement, the colony accepted transported convicts from 1850 to supply labour for public works and construction. Perth was proclaimed as a city by Queen Victoria in 1856. Substantial population growth occurred during the late 19th-century Western Australian gold rushes, and the city has continued to expand, particularly after World War II due to a high net migration rate. Post-war immigrants were predominantly from the British Isles and Southern Europe, while more recent arrivals see a growing population of Asian descent. During the late 20th and early 21st centuries, a series of mining booms in various regions of Western Australia propelled Perth into the role of the regional headquarters for significant mining operations. It became Australia's fourth-most populated city in 1984, overtaking Adelaide.

Ranked as one of the world's most liveable cities, Perth was classified by the Globalization and World Cities Research Network as a Beta global city in 2020. As of 2021,^[update] Perth is divided into 30 local government areas, comprising over 350 suburbs. The metropolitan contours span 125 kilometres (78 mi) from Two Rocks in the north to Singleton in the south, and 45 kilometres (28 mi) from the west coast to Sawyers Valley in the east. Beyond the central business district, predominant urban centres within the metropolitan area include Armadale, Fremantle, Joondalup, Midland and Rockingham. Most of those were originally established as separate settlements and retained a distinct identity after being subsumed into the wider metropolitan area. Mandurah, Western Australia's second-largest city, forms a conurbation with Perth along the coastline. Despite this, it is generally regarded as an independent city.

Perth is home to many parkland areas and nature reserves, the most-visited being Kings Park and Botanic Garden, one of the world's largest inner-city parks. Other popular natural features include Cottesloe Beach and Rottnest Island. Notable heritage buildings and cultural sites include Perth Mint, WA Museum Boola Bardip and the World Heritage-listed Fremantle Prison. All five of Western Australia's universities are based in Perth. The city is served by Fremantle Harbour and Perth Airport.

The name of the city is taken from Perth, Scotland, in honour of the Secretary of State for War and the Colonies, and Member for Perthshire in the British House of Commons, Sir George Murray. Murray's association with the city was included in Stirling's proclamation of the colony, read in Fremantle on 18 June 1829, which concluded with the statement, "Given under my hand and Seal at Perth this 18th Day of June 1829. James Stirling Lieutenant Governor". The only contemporary information on the source of the name comes from Charles Fremantle's diary entry for 12 August 1829, which records that they "named the town Perth according to the wishes of Sir George Murray".

The Noongar name Boorloo is sometimes used to denote the central business district area, the local government area, or the capital city in general. The name Boorloo was initially recorded by Robert Menli Lyon as Boorlo in 1833, which was interpreted as "Perth, properly Point Fraser" (a location in East Perth). He also gave the name Byerbrup for "the highland stretching along from Mount Eliza through the centre of the town of Perth". In 1947, Ludwig Glauert posited that Lyon may have misunderstood his sources and that "boorloo" or "belo" (now transcribed as "bilya") is simply the Noongar word for "river". Another source has interpreted Boorloo to mean "big swamp", describing the chain of lakes where the central business district and Northbridge are situated.

In November 2024, when announcing the opening of Boorloo Bridge, the premier of Western Australia, Roger Cook, and two of his ministers, deputy premier Rita Saffioti and John Carey, referenced "the Noongar name for Perth – Boorloo", and earlier in the year the Government of Western Australia stated "the name, Boorloo Bidee Mia, represents 'Perth pathway to housing' in Whadjuk Noongar language".

Archaeological evidence attests to human habitation in the Perth area for at least 48,000 years; according to Noongar tradition, they have occupied the area since "time immemorial". Noongar country encompasses the south-west corner of Western Australia, with particular significance attached to the wetlands on the Swan Coastal Plain, both spiritually (featuring in local mythology) and as a source of food.
