Hillarys is a northern coastal suburb of Perth, the capital city of Western Australia, in the local government area of the City of Joondalup. It is part of the Whitfords precinct, and is located 21 km north-northwest of Perth’s central business district. In preparation for Australia’s defence of the 1987 America’s Cup at Fremantle, the State Government commissioned the building of Hillarys Boat Harbour, the first major marina in the north metropolitan area. Hillarys Boat Harbour is also home to the Aquarium of Western Australia (AQWA). Hillarys is mostly a residential suburb, and relies on Westfield Whitford City, a large shopping centre in its northeast, and the smaller Hillarys Shopping Centre on Flinders Avenue for commercial services.
