About
Why Tethra exists
Too many mining and industrial operations spend money on consulting that produces reports but not results. Leaders get advice that sounds right in a boardroom but falls apart on site.
Tethra was built to do it differently. Senior, practical advisory for operations leaders who need someone to look at their business honestly, tell them what is actually going wrong, and help them fix it.
No large teams. No junior consultants learning on your time. Just experienced people who have worked in the industries they advise.
Founder
Mark Mullins
Mark Mullins has spent over two decades working in and around mining and heavy industry across Australia. His background spans operational leadership, workforce strategy, and business management, with deep experience across gold, iron ore, lithium, and industrial services.
Before founding Tethra, Mark built and led a specialist recruitment business serving the resources sector. That experience gave him an uncommon perspective on why operations succeed or struggle: he has seen hundreds of teams from the inside, assessed thousands of leaders, and learned what actually makes the difference between a site that runs well and one that just gets by.
Tethra is the consulting firm Mark wished existed when he was advising clients on their people and operational challenges. Practical, senior, and direct.
Approach
How we work
Three steps. No twelve-month programmes. No death by PowerPoint.
Understand
We spend time on your site, talk to your people, and look at your data. No assumptions, no templates.
Plan
A short, honest assessment of what needs to change and a practical plan to do it. You will know exactly what you are paying for.
Deliver
We work alongside your team to implement changes, build capability, and make sure improvements stick.
Senior from day one
You work directly with experienced consultants. No bait and switch, no graduate teams doing the heavy lifting.
Practical, not theoretical
We work on your site, with your people, using your data. Recommendations are built to be implemented, not just presented.
Honest and direct
If something is broken, we will say so. If something is working, we will not try to change it. You hire us for clarity, not comfort.
