The more useful comparison is internal, since heavy duty mechanic listings in the same city pay $23,000 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 $189,000, 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.
