The C6 slewing mobile crane is one of the most widely used pieces of heavy lifting equipment in Australian construction, mining, logistics, and manufacturing. Unlike smaller non-slewing cranes, a C6-class crane can rotate a full 360 degrees on its base, giving operators the flexibility to position and move heavy loads with precision in tight or congested work sites.
Under Australian Work Health and Safety (WHS) regulations, anyone operating a slewing mobile crane with a maximum rated capacity of up to 60 tonnes must hold a National High Risk Work Licence (Class C6). This licence confirms that the operator has the practical skills and theoretical knowledge to run this kind of equipment safely and in compliance with national standards.
What Is the C6 Licence?
The C6 High Risk Work Licence covers slewing mobile cranes with a lifting capacity of up to 60 tonnes. It is issued under the nationally recognised unit of competency TLILIC0023 – Licence to operate a slewing mobile crane (up to 60 tonnes capacity).
Holding a C6 licence doesn’t just qualify you to operate slewing cranes. It also allows you to operate:
- Any mobile crane up to 60 tonnes
- Non-slewing cranes, such as telehandlers or Franna cranes
- Vehicle loading cranes, such as Hiab and Palfinger units
This makes the C6 one of the more versatile high-risk work licences available, and a strong asset for anyone building a long-term career around heavy lifting equipment.
What Does the C6 Course Cover?
The C6 Slewing Mobile Crane course is delivered by a Registered Training Organisation over five days, combining theory and hands-on practical assessment. By the end of the course, participants will have developed the skills and knowledge to:
- Plan operations — hazard identification, risk management, and site consultation
- Carry out pre-operational inspections — checking the crane and associated lifting equipment before use
- Set up the crane — outriggers, boom configuration, and rigging equipment
- Transfer loads — safely shifting loads using slings and other lifting gear
- Conclude operations — safely shutting down and packing up equipment according to site-specific procedures
Because the margin for error with a 60-tonne crane is so small, safe practice has to become second nature well before an operator is working solo on site. Our guide on C6 crane safety checklist: best practices before every shift walks through the pre-start routine every operator should follow, and it’s worth reviewing alongside your course notes.
Who Can Enrol?
To enrol in the C6 Slewing Mobile Crane course, you must:
- Be at least 18 years of age
- Provide valid photo identification
- Pass a basic literacy and numeracy assessment
No prior crane licence is required to start the C6 course itself, though many operators progress into it after holding a C2 licence or working in a related trade such as dogging or rigging.
What Do You Receive on Completion?
Once you successfully complete the course and assessment, you’ll receive a nationally recognised Statement of Attainment. This document allows you to apply for your High Risk Work Licence (Class C6) through your state or territory WHS authority — SafeWork or WorkSafe, depending on where you’re based.
New operators often make avoidable errors in their first few months on the job, simply because a habit hasn’t been drilled in yet. It’s worth reading the top 7 safety mistakes new C6 crane operators make and how to avoid them before you start work, so you know what to watch for from day one.
Career Opportunities With a C6 Licence
Demand for licensed crane operators remains strong across Australia’s construction and resources sectors. With a C6 licence, common career paths include:
- Crane operator — operating the crane safely and efficiently on site, including day-to-day maintenance checks
- Crane mechanic — servicing and repairing crane equipment
- Crane inspector — verifying that cranes meet safety regulations and are fit for use
Qualified C6 operators are in demand across construction, civil infrastructure, mining, logistics, and shutdown work, with opportunities to progress further into higher-capacity licences, such as C0 for cranes over 100 tonnes, as experience builds.
Why This Course Matters
Operating a 60-tonne slewing crane is high-risk work by definition. Proper training reduces the chance of dropped loads, boom collisions, and outrigger failures — all of which can be catastrophic on a busy site. The C6 course exists to make sure every licensed operator understands load charts, crane components, and safe lifting principles before they’re trusted to run the equipment unsupervised.
