A VOC, or Verification of Competency, is a practical assessment that confirms a worker can still safely and competently perform a specific task or operate certain plant and equipment to the required workplace standard. It is not a training course and it does not teach new skills. Instead, it checks that someone who already holds a ticket, licence or unit of competency can still apply that knowledge and skill on site.

VOCs are common across construction, mining, oil and gas, transport, warehousing and heavy industry, where a mistake operating machinery or performing high risk work could cause serious injury or damage. If you work in these industries, there is a good chance an employer or site will ask you to complete a VOC before you start.

What Does a VOC Actually Involve?

A VOC is a structured, practical check carried out by a qualified assessor, usually through a Registered Training Organisation (RTO). Rather than sitting through a full course, you demonstrate that you can operate the equipment or perform the task safely using the actual procedures and conditions you would encounter on the job.

In plain terms, it is a way of proving you can still do the job safely with real equipment, not just that you once passed a course. The assessment typically includes a short knowledge check and a practical demonstration, and it produces documented evidence that you were assessed as competent on that date.

Why Do Employers Require a VOC?

Under Australian Work Health and Safety (WHS) laws, a person conducting a business or undertaking (a PCBU) has a duty to ensure workers are competent to perform the tasks they are assigned. That duty goes beyond simply sighting a licence or a training certificate. A qualification confirms someone was competent at the time they were assessed, but skills and knowledge can fade if they are not applied regularly.

A VOC gives employers documented proof that a worker can currently perform a task safely in real-world conditions. This helps the business meet its duty of care, demonstrate due diligence, reduce the risk of incidents and satisfy site and audit requirements. For workers, holding current VOCs is a strong way to prove your skills and boost your employability in high risk industries.

Who Needs a VOC?

VOC assessments are most commonly required for workers performing high risk work or operating plant and equipment where an error could result in serious harm. Typical examples include operators of forklifts, cranes, elevated work platforms, earthmoving equipment and other high risk machinery, as well as workers performing tasks such as working at heights or confined space entry.

You may be asked to complete a VOC when you start a new job, when you are mobilising onto a new project or site, when a company wants to verify your skills before allocating high risk tasks, or as part of preparing for a WHS audit. Many sites simply will not let you operate certain equipment until a current VOC is on file.

How Often Do You Need a VOC?

There is no single national law that sets one fixed VOC interval, so the requirement often comes from the site or employer rather than legislation. That said, a widely used industry benchmark is every two years, and many sites will not consider a worker current against a unit of competency if the evidence is more than 24 months old. Some sites and roles require a VOC every two to three years, or whenever a worker starts a new job.

Because the exact requirement varies between sites, it is always worth confirming what your specific employer or project expects so you can keep your evidence current and avoid delays getting on site.

What Is the Difference Between a VOC and a Licence?

A High Risk Work Licence is a formal regulatory licence issued by a state or territory authority, and it is legally required for certain classes of high risk work such as forklift operation, dogging, rigging and crane operation. A VOC is different. It is a workplace assessment that confirms current competency, and it is not a substitute for a licence.

There is one important limitation to understand. If a high risk work licence has expired, a VOC is not suitable for regulator licensing purposes. To reinstate an expired HRWL you generally need to complete the full training and assessment again. A VOC verifies current ability for a worker who already holds the relevant licence or qualification; it does not renew or replace the licence itself.

What Is the Difference Between a VOC and a Refresher?

These two are easy to confuse. A refresher is training delivered against a nationally recognised unit of competency, designed to update your skills and knowledge and, where relevant, renew that unit. A VOC is purely an assessment that verifies your existing competency without delivering new training.

In practice, some sites accept a VOC as evidence of current competency, while others require a full refresher, particularly where legislation, technology or best practice has changed. Always check what your employer or site induction specifies, as the two are not automatically interchangeable.

How Do You Prepare for a VOC?

To sit a VOC you must generally already hold the relevant current High Risk Work Licence, plant ticket or unit of competency, since a VOC verifies existing skills rather than creating them. On the day, bring your photo identification and evidence of your existing licence or qualification, and wear appropriate personal protective equipment such as steel-capped boots and any site-required clothing.

The assessor will confirm your knowledge and watch you perform the task safely, then issue documented evidence of the outcome. It is a focused, efficient process, and being familiar and current with the equipment is the best preparation.

Conclusion

A Verification of Competency is a practical, documented check that confirms a worker can still perform a specific high risk task or operate equipment safely to workplace standards. It is not a course, not a licence and not automatically the same as a refresher, but it is a vital part of meeting WHS obligations and keeping workers safe. For employers it provides proof of due diligence, and for workers it is a powerful way to stay job-ready and get onto site without delay.
