Job description

If you're a heavy diesel mechanic anywhere in QLD and you've wanting a serious career move - then this is it!

A world-class OEM workshop in central N.QLD is looking for tradespeople who are open to relocating and stepping into the mining industry in a long-term position. You'll work residential, building a specialist skillset making you seriously marketable for the rest of your mining career alongside an outdoor lifestyle most tradies chase on their days off.

• Flexible 5:2 or 8:6 roster - starting on day with 12-hr shifts
• Specialise on a challenging variety of underground mining equipment
• Collaborative, experienced workshop team with a strong culture
• Competitive hourly rate with a clear pathway to permanent employment
• Build rare underground expertise that's always in demand across mining

The Workshop Role

Reporting to the workshop supervisor, you'll be hands-on with the full range of underground mining machinery, working alongside a tight, experienced crew. Your day-to-day will include:

• Major rebuilds and heavy maintenance projects
• Component change-outs and machinery upgrades
• Commissioning, testing, and quality auditing
• Inspections and compliance checks

The Company

Join a respected global OEM with a serious commitment to developing their people - structured training, consistent workflow, and a genuine team culture that accelerates careers rather than stalling them.

• World-class OEM training - become a true underground specialist
• Stable, consistent workflow with strong earning potential
• Tight-knit, supportive team with genuine mentorship culture
• Real temp-to-perm pathway

Location & Relocation

If you've been chasing big mining money while sacrificing time at home, this is the rare role where you don't have to choose.

Your Skills & Experience

You'll come from a heavy vehicle, civil or earthmoving background. Mining exposure is a bonus but not needed - what matters most is your attitude and your foundation as a tradesperson.

• Previous mining experience - underground a definite advantage
• Strong work ethic with a genuine commitment to safety and quality
• Ready to relocate to Mount Isa and commit to the role
• Drive to develop into a true underground mining specialist
• Interest in stepping into a leadership and mentoring capacity over time
• Motivated to convert from temp to permanent role
