Who Taught the Supervisor? The Overlooked Charge in the Chinchilla Apprentice Death

On 17 December 2021, a 16-year-old school-based first year apprentice was crushed and killed at a heavy vehicle repair business in Chinchilla when an inadequately supported truck body collapsed. Its on-board safety prop had been deployed in the wrong position and at the wrong angle with the bin still loaded. In August 2026 the Chinchilla Magistrates Court fined the company $550,000 and its sole director $100,000, with a conviction recorded against the director.

Most people reading that will focus on the prop. They should. But the part of this case I keep returning to is the second charge. The workshop managers supervising two 16-year-old apprentices had themselves never been trained or instructed in how to supervise young workers. They relied on their own experience in allotting tasks.

The Duty Nobody Writes Down

This is one of the quietest gaps I see in otherwise well-run workplaces. A business will invest in training apprentices. It will induct them, give them PPE and sign them up to a training provider. What it rarely does is ask whether the person standing next to that apprentice knows how to supervise someone who is 16.

Supervising a young worker isn't the same as supervising an experienced tradesperson. Young workers are less likely to recognise a hazard and less likely to question an instruction. They are also more likely to try a task they haven't been shown rather than admit they don't know how. A supervisor who has never been told any of this will default to how they were supervised. That might have been a very long time ago.

Ask Yourself About Your Supervisors

• Has anyone who supervises apprentices, trainees or school-based workers been given specific instruction on supervising young people?
• Is there a written list of tasks a first year apprentice can do alone, can do under direct supervision and must not do at all?
• Who decides which tasks get allotted to a young worker each day? On what basis? Is it a system or is it experience?
• Would your supervisors recognise when a young worker is out of their depth but not saying so?
• If a supervisor is on leave, does the replacement know the same limits?

Competence Has to Be Tracked, Not Assumed

A second story in this week's brief sits right beside Chinchilla. In South Australia, Jumbuck House Pty Ltd and Mulgathing Pty Ltd have each been charged over the 2024 death of a station pilot conducting aerial sheep mustering at Mulgathing Station without an aerial mustering endorsement. SafeWork SA alleges there was no system for tracking workers' qualifications and endorsements across the subsidiaries. It also alleges induction and supervision were inadequate.

Different industry, different age group. The same underlying question though. Did anyone actually know whether the person doing the work was competent to do it, or was it assumed? And did anyone know whether the person overseeing them was equipped to oversee?

In both cases the answer appears to have rested on someone's experience rather than on a system. Experience is valuable. But it isn't a control, because it can't be checked and it leaves with the person who holds it.

A Simple Starting Point

If you employ apprentices or young workers, list every person who supervises them. Next to each name, write down what training or instruction they have had in supervising young workers specifically. If that column is mostly blank, you're in the same position the Chinchilla business was in before 17 December 2021.
