Perth's employment market is strongly linked to the fortunes of Western Australia's resources sector, but the city's economy has diversified considerably. Mining, oil and gas and resources services remain the highest-wage employers, with major companies including BHP, Rio Tinto, Woodside Energy, Fortescue and a deep supply chain of engineering, maintenance and professional services firms headquartered in the CBD and West Perth. The Perth-based operations of these companies generate substantial white-collar, technical, project management and corporate employment even for workers who never set foot on a mine site. Healthcare is the second major employment pillar, with Fiona Stanley, Royal Perth, Sir Charles Gairdner and Perth Children's hospitals among the major hirers, alongside a large private hospital and NDIS provider network.

Construction has been one of Perth's most active employment sectors over recent years, sustained by a residential building boom, infrastructure investment in Metronet rail extensions and road projects, and commercial development in the CBD and outer suburbs. Technology and professional services have grown significantly, with a cluster of digital, fintech and consulting businesses establishing in Perth attracted by its talent pool and business costs. For Jobseekers, Perth offers the combination of major city career opportunities, high average wages relative to national benchmarks, and a lifestyle centred on beaches, outdoor recreation and a genuinely sunny climate.
