Frequently Asked Questions

What is a good starting salary for a junior Heavy Diesel Mechanic in Perth?
A heavy diesel mechanic starting in Perth earns from around $117k, already high because the trade is tied to well-paid resources work. FIFO rosters, mobile-plant and earthmoving specialisation, and OEM-specific certifications are what push pay toward the $185k top of the band.
Is $138,320 a good salary in Perth?
Yes. At $138k the median runs 38% above Perth's $100k all-roles median and nets roughly $99k after tax, strong even in a resources-inflated city. The caveat is timing: pay eased this month as resources hiring cooled, so the peak numbers of a few months ago may not hold.
How much does a Senior Heavy Diesel Mechanic make in Perth?
There is no separate senior band here, but the $185k top decile shows what FIFO and specialised mechanics earn on mine sites. Getting there is about roster type and OEM or mobile-plant credentials rather than workshop tenure, with supervisor and maintenance-planner roles the next step.
