Duncraig, WA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Duncraig is a leafy residential suburb in Perth's northern suburbs, about 16 km from the city centre between Marmion Avenue and the Mitchell Freeway, within the City of Joondalup. Little was developed here before the 1960s; the Scottish-sounding name Duncraig was approved in 1969 and first used to promote the new estates. Most of the suburb was built through the mid-1970s, its schools, library and shopping centres rising almost in step with the housing, and in 1986 the extension of the Mitchell Freeway linked it directly to central Perth. One of Duncraig's quirks lies in its north-western corner, where a cluster of streets is named after Gilbert and Sullivan operas and their characters — Gilbert Road meets Sullivan Road near Savoy Place and Pinafore Court. The suburb has produced some notable residents, including Formula One driver Daniel Ricciardo and Melanie Perkins, who began the graphic-design company Canva in her family's Duncraig home.
