Understanding the Perth Market

The median fell $6,570 to $150,000 with listings flat at 36. Perth carries three overlapping heavy plant titles this month: heavy duty fitter at $160,000, heavy diesel mechanic at $150,000 and general mechanical fitter at $125,000, all describing broadly similar mining maintenance work. That $35,000 spread between near-identical titles is worth knowing before accepting an offer. No other city has enough listings to compare, and only 29% of these stated a salary.

Frequently Asked Questions

What is a good starting salary for a junior Heavy Diesel Mechanic in Perth?
The $125,000 floor assumes a heavy vehicle or diesel trade qualification plus site experience, and it is exactly what general mechanical fitters earn as a median. Mine site inductions, OEM-specific training and shutdown experience are what move a mechanic up the band. General automotive and truck workshop roles sit well below this range.
Is $150,000 a good salary in Perth?
Yes. At $150,000 a heavy diesel mechanic earns 50% above Perth's all-roles median of $100,000, with take-home near $2,047 a week and moderate living costs. The more useful comparison is internal, since heavy duty fitter listings in the same city pay $10,000 more for similar work. Checking which title an employer uses is worth real money here.
How much does a Senior Heavy Diesel Mechanic make in Perth?
The ceiling is $211,000, reached through supervision, shutdown work and demanding roster arrangements rather than a different qualification. Roster type is the main lever on total earnings. Maintenance supervision and superintendent roles sit above this range.
