RII Supervisor – S123

Become a certified mine supervisor, also known as G189, G1 G8 G9, QMS and MSSSContact Us

Description

S1 S2 S3 training is the nationally recognised pathway for mine workers stepping into a supervisory role in Queensland. It is designed for experienced workers ready to take on responsibility for a team, a shift, or a section of a mine site. No prior supervisory experience is required to enrol.

The course covers the core competencies needed to lead and manage safely in a mining environment. Successful participants leave with a nationally recognised qualification that meets Queensland’s statutory requirements for supervision roles on mine sites. This satisfies the regulatory obligations set out under Queensland mining legislation for anyone appointed to a supervisory position. 

This program is ideal for workers moving into supervisory duties or those already performing them. Basic language, literacy, and numeracy are required for assessment. Participants must bring government-issued photo ID and their USI. Supervisors must refresh their competencies every 5 years — see the S123 Refresher for details.

Training covers:

  • Applying risk management processes
  • Conducting safety and health investigations
  • Communicating and reporting effectively onsite
  • Supervisor responsibilities aligned to Queensland mining legislation

Units of Competency:

  • RIIRIS301E – Apply risk management processes
  • RIIWHS301E – Conduct safety and health investigations
  • RIICOM301E – Communicate information

Delivery is two full days (7:45am–4:00pm), delivered through classroom learning, group discussions, and case-based activities. Locations include Emerald, Moranbah, and TAFE Eagle Farm (Brisbane).

Assessment includes theory activities and practical tasks mapped directly to the S123 outcomes. Certificates are issued 2–3 business days after competency is met, payment is confirmed, and USI verification is completed.

These terms all refer to the same qualification or its direct equivalent. The naming has changed over time as the national competency framework was updated, and different sites and providers use different codes, but the underlying certification is the same.

S1, S2 and S3 can be completed as separate units or as a combined course depending on your prior recognition and the delivery schedule available. Contact the team to confirm the right enrollment pathway for your situation.

Course duration varies depending on whether you are completing all three units or individual components. Contact us directly for current scheduling and delivery timeframes at your preferred location.

Bring valid photo identification, your USI, and any evidence of prior training or competencies if you are seeking recognition of prior learning. Wear appropriate clothing for a training environment and arrive on time for the scheduled start.

If you do not pass the assessment, you will have the opportunity to be reassessed. The trainer will give you feedback on where you need to focus, and the pathway to resubmission will be outlined clearly at the time.

Certificates are typically issued within a short period following successful completion and assessment. Contact the team at enrolment if you have a specific start date requirement so this can be factored in.
