Adelaide Mechanic Banned from Taking on Apprentices After Leaving Trainees Unsupervised

Introduction
An Adelaide mechanic has been banned indefinitely from employing apprentices after he left two trainees to run his service centre alone while he went on holiday. The unprecedented disciplinary action has sparked discussion about employer accountability and apprentice safety in South Australia’s vocational training sector.

Details of the Case
Scott Thornton, a former owner of Ultra Tune franchises at Aberfoyle Park and Seaford, was found to have left two apprentices unsupervised for a week. South Australia’s Skills Commissioner Cameron Baker described the conduct as “some of the most extreme” he had seen in his tenure.

“When apprentices and trainees are left alone, that’s when injuries happen. And dare I say, that’s when fatalities can happen,” Baker said.

The ban marks only the second time in state history that such powers have been used to prohibit an employer from hiring apprentices. Earlier this year, a Domino’s franchisee was handed a similar penalty following breaches of training and safety obligations.

Thornton’s Defence
Thornton defended his decision, arguing that the apprentices were capable of managing the workshop independently.
“It was my understanding at the time that senior apprentices could work unsupervised. They had been in the trade for three-plus years and were more than capable of doing basic servicing,” he said.

He also highlighted his long-standing record as a trainer:
“I’ve been training apprentices for 20-plus years and never had a problem. My track record is unblemished.”
Thornton has indicated his intention to appeal the decision and hopes to employ apprentices again in the future.

Government and Regulator Response
Education Minister Blair Boyer said the decision sends a clear message that the welfare of trainees cannot be compromised.
“We know apprentices are vulnerable because of their age and the fact they are starting out. We take this very seriously and want to make sure apprentices are safe at work.”

Commissioner Baker reinforced that the disciplinary action is about setting precedent and deterrence:
“This case demonstrates that when employers fail in their duty of care, there will be serious consequences.”

Broader Context
Apprenticeship supervision has become a growing concern for regulators, particularly in high-risk trades like automotive servicing, construction, and electrical work. Industry bodies have warned that unsupervised training environments not only endanger young workers but can undermine the integrity of the vocational system.

South Australia’s training oversight framework gives the Skills Commissioner authority to suspend or permanently ban employers who breach workplace and training obligations, particularly where safety or competency risks are identified.

Conclusion
The ban on Scott Thornton serves as a high-profile warning to businesses about the duty of care owed to apprentices. While Thornton maintains he acted in good faith, authorities say the outcome reinforces the fundamental principle of vocational safety — that supervision and training must never be compromised for convenience.
