Operator competency sits at the centre of plant safety and productivity, whether the operator comes with a wet hire or from your own crew. Australian requirements combine licensing for certain high risk work with a broader duty to ensure workers are trained and competent for the plant they use. This guide explains the main elements and how to check them without relying on paperwork alone.
01 / High risk work licences
Under the harmonised work health and safety framework, certain classes of work require a high risk work licence issued by a state or territory regulator. These include operating forklifts, many types of cranes, boom-type elevating work platforms where the boom length is 11 metres or more, and work such as dogging, rigging and scaffolding. Licences are generally recognised across jurisdictions, and each licence class covers specific plant.
Check that the licence class matches the plant and task, that it is current, and that it belongs to the operator on site. Many regulators offer an online licence check. Note that a licence confirms the holder met a standard at assessment; it does not confirm experience with a particular make, model or site condition. For operated crane hire, also confirm the licensing of the dogman or rigger working with the crane, whoever supplies them.
02 / Plant that does not require a licence
Much common earthmoving plant, including excavators, loaders, rollers and dozers, does not require a high risk work licence in most jurisdictions under the current framework. The same applies to scissor lifts and boom-type platforms under the 11 metre threshold. That does not reduce the duty to ensure the operator is competent; it means competency must be demonstrated in other ways, such as nationally recognised training and workplace assessment.
Because there is no single licence to check, contractors and principal contractors typically set their own requirements. These might include a statement of attainment in a relevant unit of competency, a verification of competency on the specific machine, and a documented record of experience. If you are unsure what applies to a machine or jurisdiction, check the regulator's guidance rather than relying on what was accepted on a previous project.
03 / Verification of competency
A verification of competency, or VOC, is an assessment confirming that an operator can safely operate a particular type of plant in the relevant conditions. It is not a licence and is not usually defined in legislation, but it is widely used across construction, civil and resources work as evidence that a person's skills are current. Many sites require VOCs to be renewed periodically, and some require them for each machine type.
When reviewing a VOC, check who conducted it, what plant and attachments it covers, the date, and whether it included practical assessment rather than a document review. A VOC from a reputable assessor for the same make and class of machine is more useful than a generic one. For wet hire, ask the supplier to provide current VOCs for the nominated operator before mobilisation, and for any replacement operator.
04 / General induction and site-specific inductions
Anyone carrying out construction work in Australia generally needs to complete general construction induction training, commonly known as the White Card. It is a baseline requirement covering construction hazards and basic safety, and it does not relate to any particular machine. Check that the operator holds a card and that it was issued by a registered training organisation, keeping in mind that card formats and issuing arrangements vary between states.
Site-specific inductions then cover the hazards, rules and emergency arrangements for your project. For plant operators, that should include traffic management plans, exclusion zones, underground and overhead services, ground conditions, communication methods and the pre-start process. A short machine-specific walk-around with the site supervisor on the first day often catches issues that an induction presentation cannot, such as a blind spot near a busy pedestrian route.
05 / Confirming competency in practice
Paperwork establishes a minimum; observation confirms it. In the first hours of a hire, supervisors should watch how the operator conducts the pre-start check, sets up, communicates with spotters and responds to changing conditions. Warning signs include skipped checks, unfamiliarity with the controls or attachments, and reluctance to stop when conditions change. Raising concerns early is far easier than addressing an incident later.
Keep records in a form that can be retrieved quickly: licence details and verification dates, VOC copies, induction sign-off and any supervisory observations. For wet hire, agree with the supplier in advance how an operator will be replaced if competency concerns arise. For dry hire, set a clear rule about who may operate each machine, because damage waivers and insurance often exclude damage caused by unauthorised operators.
Field checklist
- Confirm whether the plant and task require a high risk work licence
- Check the licence class, currency and holder identity with the regulator where possible
- Obtain a current VOC covering the specific machine type and attachments
- Confirm the operator holds a White Card for construction work
- Complete a site-specific induction covering plant hazards and exclusion zones
- Observe the first shift, including the pre-start check and set-up
- Record who is authorised to operate each hired machine
Frequently asked questions
What is an operator VOC?
A VOC, or verification of competency, is an assessment confirming that an operator can safely use a particular type of plant under relevant conditions. It is not a government licence, but many principal contractors and sites require one. Check who carried it out, what plant it covers and when it was completed.
Do you need a licence to operate an excavator in Australia?
Under the current harmonised framework, excavators do not generally require a high risk work licence. Operators must still be competent, and sites commonly require evidence such as nationally recognised training, a VOC and relevant experience. Check your regulator's guidance for your jurisdiction, as requirements and site rules can differ.
When does an elevating work platform need a licence?
A high risk work licence is generally required to operate a boom-type elevating work platform where the boom length is 11 metres or more. Scissor lifts and shorter boom lifts do not usually require a licence, but operators still need appropriate training and competency. Check the regulator's guidance if you are unsure about a specific machine.
Is a White Card enough to operate plant?
No. The White Card is general construction induction training that covers basic safety on construction sites. It does not demonstrate competency to operate any particular plant. Operators also need a relevant high risk work licence where one is required, and suitable training and assessment for the machine they will use.
