Garden Island Suburb Profile

Garden Island is Perth's most restricted suburb, a working naval base (HMAS Stirling / Fleet Base West) sitting off the Rockingham coast, connected by a causeway that's firmly off-limits to the public. Home to a tiny civilian community, ASC submarine workers, and allied defence personnel, it's defined by security gates, spectacular coastal scenery, and a growing role in Australia's AUKUS submarine program. Visitors can only admire it from the water or a drone.

The commute to Perth CBD is a 60-minute drive by car, and most residents drive (47%). With a safety score of 98/100, the area rates 46 points above the Perth metro average of 52, with low rates of both property crime and violent offences.
