About the role

Nitro Crushing is seeking a trade-qualified Crushing Fitter to join us in Cairns and keep our Far North Queensland crews running. This is a hands-on field role — you'll be out on quarry and mine sites, travelling and staying away as the work schedule requires, with Cairns as your home base. Reporting to the Maintenance and Parts Supervisor, you'll be the fitter on the ground — responding to breakdowns, changing wear parts, running scheduled services, and keeping the plant turning alongside the crushing crew.

This is a residential Cairns role, not FIFO from elsewhere. You'll live locally, work with the same FNQ crews, and head out to site when the schedule calls for it. Travel and accommodation are covered when you're away.

- Diagnose and rectify mechanical, hydraulic, pneumatic and basic electrical faults on crushers, screens and conveyors

- Change wear parts — jaw plates, cone liners, blow bars, screen media, skirting and conveyor rollers
- Complete cone and jaw changes, mantle and concave replacement
- Welding, oxy cutting and general fabrication repairs to plant, chutes and guarding
- Service and maintain loaders, excavators, gensets and site support equipment
- Assist with plant set-up,
