Understanding the Perth Market

The median lands exactly on Perth's all-roles baseline: $100k against $100k, a zero-gap result that is high for an administrative title and marks this out as a resources-sector role, not a standard office job. The band is wide, $84.4k to $125k, reflecting site allowances and FIFO loadings. Demand is solid at 35 listings. What lifts this well above ordinary Perth admin pay is the mining and construction site context.
