Yanchep, WA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Yanchep is a coastal suburb on the northern edge of the Perth metropolitan area in Western Australia, about 56 km north of the city centre. Its name is thought to derive from a Noongar word, recorded as 'Yandjip' or 'Yanget', for the bulrush reeds that grow around the area's wetlands. Long a small crayfishing and holiday settlement, it was promoted from 1970 by businessman Alan Bond as a 'Sun City' resort before the project later passed to Japanese developers. Today it is one of Perth's fastest-growing outer suburbs, reached by a railway extension that opened in 2024. The adjoining Yanchep National Park is a major drawcard, with Loch McNess, limestone caves, walking trails and a colony of koalas.
