Western Australia

Western Australia is the country's largest state by area — covering roughly a third of the continent — and has a population of about 2.9 million, the majority of whom live in metropolitan Perth on the Indian Ocean coast. The state's economy is anchored by iron ore and natural gas exports from the Pilbara and the North West Shelf, supplemented by gold from Kalgoorlie, agriculture in the Wheatbelt, and tourism through the Margaret River wine region and the Ningaloo and Rottnest coastlines. Western Australia operates on a time zone two hours behind the eastern states and is closer, by some flights, to Singapore than to Sydney.

Plates issued in Western Australia follow the 1ABC-456 format: one digit, three letters, then three digits, e.g. 1ABC-456. The current series is administered by the Department of Transport on a white base with black characters and a black swan emblem — the state's symbol, taken from the Swan River around which Perth is built. The seven- character alphanumeric pattern has been the default since the late 1990s. The black swan emblem distinguishes WA plates at a glance from the mainland-east issues and is one of the few state insignia that appears on the plate face itself rather than only on the wordmark.

Western Australian plate strings carry no regional signal. A plate first issued in Geraldton or Karratha looks identical, in form, to one issued in central Perth. The Department of Transport runs personalised and custom-content series alongside the standard issue; those sit outside the standard validator. Heavy vehicles, trailers, and motorcycles each carry their own parallel sequence. The 1ABC-456 shape is what you will see on the vast majority of passenger cars on a Western Australian road today.
