Why Completing the G189 (Formerly S123) Mining Supervisor Course Online is Good for Business

The G189 Mining Supervisor Course (formerly known as S123) is a nationally recognised qualification required for those supervising teams in the mining and resources industry. For businesses, enabling employees to complete this training online through a Registered Training Organisation (RTO) like Core Crew Training – is not only convenient, it’s a smart strategic move.

Here’s why opting for online G189 training benefits both your people and your bottom line:

1. Minimises Downtime

In a 24/7 industry like mining, every hour counts. Online delivery allows team members to complete their G189 training at their own pace, without needing to travel off-site or take extended time away from their role. This flexibility helps maintain operational continuity while ensuring compliance.

2. Improves Safety Leadership On Site

The G189 course covers critical components of mine site supervision – risk management, safety systems, communication, and leadership. By making this training accessible online, businesses can accelerate the development of capable, safety-focused leaders who are ready to step up when needed.

3. Cost-Effective Training Solution

Online delivery often reduces training costs for businesses. There are no travel or accommodation expenses, and course fees are generally lower than in-person alternatives. This makes the G189 online course a cost friendly solution for developing your workforce.

4. Meets Compliance Requirements

In Queensland and other mining regions, holding a G189 (formerly S123) certificate is a requirement for all mining supervisors. Online training through a certified RTO ensures your team is meeting these compliance standards while staying productive.

5. Scalable for Teams

Whether you’re onboarding a new crew or upskilling future supervisors, online training makes it easy to roll out the G189 course to multiple team members at once—across multiple locations if needed.

Investing in online G189 Mining Supervisor training is a practical, efficient, and forward-thinking move for any mining business. It supports regulatory compliance, strengthens your leadership capability, and delivers training that works with the realities of site operations.

Make it easier for your team to get certified.
