If you’ve been eyeing off a supervisor role or you’ve been tapped on the shoulder to step up, you’ve probably heard the same line:
“You’ll need your G189.”
But what does that actually mean? And more importantly, what do you genuinely learn from a G189 course that helps you do the job?
Let’s cut the fluff.
Completing a leading G189 online course isn’t about ticking a box. It’s about building the core skills that real mining supervisors rely on every single day, often without even realising it. Whether you’re aiming to get qualified for your supervisor job or you’re already unofficially supervising the crew, the G189 bridges the gap between industry experience and formal capability.
Here’s what the G189 really gives you.
Every mining supervisor faces this moment:
A job stops. Something feels off. A risk pops up that wasn’t in the JSEA. Two operators disagree on the best approach.
This is where the G189 training becomes gold.
The course teaches practical, structured decision-making using risk management frameworks that align with mining requirements and legislation. Not paperwork for paperwork’s sake, but the exact thought process that keeps jobs moving safely and protects you when things get questioned later.
You’ll learn how to:
Supervisors with strong industry experience often say they wish they’d learned this sooner, because once you understand the “why” behind the paperwork, the job gets easier, not harder.
Here’s the real shift: Going from operator to supervisor is a mindset change.
The G189 helps you transition from “doing the work” to “leading the work,” which is where most new supervisors struggle. Good leadership isn’t about being the loudest voice or the bossiest person, it’s about clarity, consistency, communication, and accountability.
In the G189, you learn how to:
These are the real-world skills that keep crews tight, productive, and switched on.
And yes…. the course also tackles the classic supervisor headache: managing mates.
It gives you practical tools for maintaining respect without compromising your authority.
This part surprises most people.
A lot of operators stepping into supervisor roles know the job, but they don’t fully understand the legal weight that comes with the position. As a supervisor, you’re responsible for ensuring work is conducted safely and in line with site obligations and the G189 lays this out clearly.
You’ll learn how mining law actually applies in everyday work, including:
This is designed to give you the confidence to do the job properly and protect yourself and your crew.
Being a mining supervisor means you’re constantly communicating:
pre-starts, radio calls, shift handovers, production updates, escalations, shutdown coordination – the list goes on.
Poor communication is the root cause of half the issues on any mine site.
A leading G189 online course focuses heavily on communication so you can:
Good communication doesn’t just support safety, it lifts production, culture, and trust.
If you’ve been in mining for a while, you’ve already got the hands-on skills.
What the G189 does is help you connect that industry experience with the requirements of leading a crew.
You learn how to:
This is what makes someone a good supervisor, not just a person wearing the title.
This is the part HR and hiring managers look for.
Completing the G189 shows you meet the formal mining requirements for frontline supervision and gives you the recognised qualification to get qualified for your supervisor job.
It’s a credential that:
And with online learning now available, you can complete the theory in your own time, without needing to take time off work.
A supervisor role isn’t just a pay rise; it’s responsibility, trust, and influence.
The G189 equips you with the skills, mindset, and qualification to step into that role with confidence, not guesswork.
If you’re ready to move up or you want your team members prepared for the next step, a leading G189 online course is one of the smartest investments you can make.
