About the High Risk Work Licence — Slewing Mobile Crane C0 (over 100t) Exam
The C0 High Risk Work Licence is the highest slewing mobile crane class and authorises operation of slewing mobile cranes with a Maximum Rated Capacity (MRC) over 100 tonnes (and, under the published mobile-crane HRWL hierarchy, the lower slewing classes). Assessment is based on TLILIC0020 Licence to operate a slewing mobile crane (over 100 tonnes). The assessment covers complex lift planning, counterweight and boom configuration, advanced load-chart interpretation (including fly/jib and rubber vs outrigger ratings), net capacity calculations, outrigger packing and ground bearing pressure (QLD CoP Option 1: 0.65×(CM+L)/area when force unknown; Option 2: Force/Area when known), multi-crane/tandem lift planning (QLD CoP §11.3.2 20%/33%/50% minimum capacity allowances, also aligned with AS 2550.1 practice), dogger communication, safe crane movements, and shutdown/securing.
Assessment
Closed-book National Assessment Instrument (NAI) theory and calculation assessment administered by an accredited assessor at an RTO, plus a practical crane operation assessment on a compliant slewing mobile crane over 100 tonnes MRC. Loads must be moved with a licensed HRW DG class dogger. Many RTOs require prior C6 (or equivalent pathway) experience and logged hours before practical assessment.
Time Limit
Closed-book NAI theory and calculation papers plus practical assessment (session timing set by the accredited assessor; courses commonly run 4–5 days face-to-face)
Passing Score
Competent — calculations and practical require 100% accuracy; critical safety theory items must be answered correctly
Exam Fee
RTO courses commonly advertise about $2,000–$4,000+ AUD for C0 training and assessment (examples: ~$2,000 Saferight WA; from ~$2,200 Harness Energy; fees vary by location and funding), plus a separate state/territory HRWL application fee typically around $75–$160 AUD (State and Territory Work Health and Safety (WHS) regulators (e.g., SafeWork NSW, WorkSafe Victoria, WorkSafe Queensland, WorkSafe WA, SafeWork SA) using the national unit TLILIC0020)

Plan Work / Task
WHS duties, C0 hierarchy vs C1/C6/C2, SWMS, hazards, powerline exclusion zones, dogging interface, critical and multi-crane lift planning.
Prepare Crane & Site
Pre-operational checks, ground bearing capacity, outrigger and packing setup, counterweight configuration, level crane, load chart selection, and boom/jib configuration.
Operate & Advanced Lift Calculations
Advanced radius and boom configuration, gross vs net capacity, hook-block/rigging/fly deductions, outrigger ground-pressure calcs, multi-crane de-rating and load share, slew and hoist control, and dogger signals.
Shutdown & Pack Up
Safe parking, boom and outrigger stowage, isolation, post-operational checks, tagging faults, and logbook entries.

Frequently Asked Questions
What unit of competency applies to the C0 slewing mobile crane licence?
The current national unit is TLILIC0020 Licence to operate a slewing mobile crane (over 100 tonnes). Competence in the unit supports the High Risk Work Licence pathway; the HRWL itself is issued by the state or territory WHS regulator after a Notice of Satisfactory Assessment. Note the class code is C0 (zero), not the letter O.
What does a C0 licence allow me to operate?
C0 authorises slewing mobile cranes with an MRC over 100 tonnes. Under the published mobile crane High Risk Work hierarchy used by Australian WHS regulators, C0 is the highest slewing class and encompasses the lower slewing classes (C1, C6, C2). Confirm current encompassment rules for CN, CV and reach stacker with your state regulator, as Model WHS crane-licence amendments may change automatic encompassment of some non-slewing classes.
What happens if I fail the calculation component of the NAI?
NAI crane calculations require 100% accuracy. Failing any calculation item results in Not Yet Competent for that component and requires reassessment per the assessor's and regulator's rules. C0 assessments place heavy emphasis on load-chart, net capacity, outrigger/ground-pressure, and multi-crane calculations.
