Ballajura, WA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Ballajura is a residential suburb of Perth, about 14 kilometres north of the city centre and part of the City of Swan. Its story begins in 1905, when Ernest Maltby Kerruish, a migrant from the Isle of Man, took up farmland on the site and named it Ballajora after a farm at Maughold in his homeland; over time the spelling shifted to Ballajura. Kerruish found the soil too poor for his liking and soon moved his operations to a vineyard at nearby Caversham, but the names of his Manx companions, Creer and Eaton, are still remembered in the houses of the local primary school. The suburb as it stands today took shape in the 1980s, when the Lakeshore and Lakes Estate subdivisions were laid out around a series of landscaped lakes and parks, drawing a wave of new family homes.
