Reading the numbers ## What does this mean for choosing a location in Western Australia? Higher spending per head and fast growth make Western Australia an attractive market, but the growth is almost all in Perth’s outer suburbs, where a site can open before its residents arrive. Timing matters as much as place: a site that is too early waits for its market. Because Perth is low-density and car-based, catchments are wide and drive times matter more than distance. Two sites five kilometres apart can share most of their residents. The mining towns earn the most but are small and remote, and depend on the cycle of the industry. For most formats they are single-site decisions, not part of a network.
