Western Australia History & Heritage Guide 2025

Aboriginal Australians have continuously inhabited what is now Western Australia for at least 50,000 years — among the oldest continuous cultural traditions on Earth. The Noongar people occupy the south-west; the Yamaji, Malgana, and other groups the mid-west; the Martu and Ngaanyatjarra the Western Desert; and numerous Kimberley groups including the Bardi, Yawuru, Bunuba, and Kija peoples the north. WA's rock art — particularly the Murujuga (Burrup Peninsula) petroglyphs — represents one of the world's largest collections of ancient rock art.

Dutch East India Company captain Dirk Hartog made the first recorded European landing on Australian soil at Cape Inscription, Shark Bay, on 25 October 1616. He left behind a pewter plate (the Hartog Plate) inscribed with his vessel's details — Australia's oldest surviving European artefact, now held in the Rijksmuseum, Amsterdam. A replica is on display at the Shark Bay World Heritage Discovery Centre in Denham.

Dutch explorer Willem de Vlamingh explored the WA coast, naming the Swan River (Zwaanenrivier) after the black swans he found there. He also visited Rottnest Island, naming it 'Rat's Nest' (Rotte Nest) due to the abundance of quokkas, which he mistook for rats. De Vlamingh replaced the Hartog Plate with his own plate.

Britain established a military outpost at King George Sound (now Albany) in December 1826, primarily to forestall French territorial claims to the western portion of the continent. This was the first British settlement in what became Western Australia.

Captain James Stirling established the Swan River Colony on 2 June 1829, with the city of Perth formally founded on 12 June 1829. Fremantle was settled the same month as the colony's port. The colony was unique in early Australian history as a free settlement (not a penal colony) — though convict transportation later began in 1850 due to chronic labour shortages.

In response to the colony's dire labour shortage, WA requested transportation of convicts from Britain. Between 1850 and 1868, approximately 9,720 male convicts arrived in WA aboard 43 ships. Convict labour built much of Fremantle's early infrastructure including Fremantle Prison (opened 1855, now World Heritage listed), Government House, and the Fremantle Courthouse. WA was the last Australian colony to receive convicts and the only one to request them.

The discovery of gold at Coolgardie in 1892 and at Kalgoorlie in 1893 triggered one of the world's great gold rushes, transforming WA from a struggling colony into a prosperous state almost overnight. The population quadrupled in a decade. Engineer C.Y. O'Connor designed and built the 560km Goldfields Water Scheme pipeline from Mundaring Weir to Kalgoorlie — one of the engineering marvels of its era. The Kalgoorlie-Boulder Golden Mile remains the world's richest gold deposit, and the Kalgoorlie Super Pit is still operating today.

Western Australia reluctantly joined the Australian Federation on 1 January 1901, following a referendum in which WA voted 44,800 to 19,691 in favour. The 'Inducements' promised by eastern states — including construction of a transcontinental railway — were key factors in the 'yes' vote. Many West Australians remained ambivalent about federation, and the state's independent spirit persisted.

At the height of the Great Depression, Western Australians voted overwhelmingly (two-thirds majority) to secede from the Australian Federation. The result was never enacted as it was deemed outside the British Parliament's jurisdiction without federal approval. The episode reflects the enduring sense of WA's distinct identity and its economic grievances against the eastern states.

Albany's King George Sound was the final assembly point and departure port for the first ANZAC convoy — 38 troop ships carrying 30,000 Australian and New Zealand soldiers — which departed on 1 November 1914, bound for Egypt and ultimately Gallipoli. The National Anzac Centre in Albany, opened in 2014 on the centenary of the departure, is one of Australia's finest museums and commemorates this momentous event.

Fremantle served as the largest Allied submarine base in the Pacific during WWII, supporting American, British, and Dutch submarines in operations against Japanese shipping throughout South-East Asia. Over 170 submarines operated from Fremantle. Rottnest Island's gun emplacements and military fortifications from this period are still visible today. The WA Museum's maritime galleries preserve this history.

The discovery of massive iron ore deposits in the Pilbara region (1962), nickel in Kalgoorlie (1966), North West Shelf natural gas (1971), and subsequent mining developments transformed WA into Australia's wealthiest state. Companies including BHP, Rio Tinto, Woodside, and Fortescue Metals have built enormous operations in the remote Pilbara. WA now accounts for over 50% of Australia's total export revenue.
