From The Pit To The Pad.
Built on one simple idea: be the team that actually shows up when downtime matters.
OMW Mechanical Services was built on one simple idea: be the team that actually shows up when downtime matters. After years working in heavy diesel maintenance across mining and civil operations, we understood what clients needed — not just another contractor, but a reliable partner who shows up prepared and solves problems properly.
We are a 100% Western Australian Indigenous owned and operated business, proud to be building long-term partnerships across the industry. Every job we take on reflects our commitment to honest communication, practical fault finding, and dependable field support.
"This business is built on showing up prepared, solving problems properly and working as part of the client's team rather than just another contractor on site."
— Brandon Nunn, Director
Our Values
These principles guide every job we take on.
Show Up Prepared
Right tools. Right parts. Ready to work from the moment we arrive on site.
Honest Communication
No guesswork passed off as diagnoses. We tell you what's wrong and what it takes to fix it.
Part of Your Team
We integrate into your operation's culture and workflow, not just turn up and invoice.
Dependable Field Support
WA-wide coverage. Remote sites welcome. If you're running, we can reach you.
