Recent Federal Court Decision
A recent Federal Court decision has brought renewed attention to the complex balance between workplace safety, operational efficiency, and employee consultation – particularly when it comes to Drug and Alcohol (AOD) policies. The case, involving Opal Packaging and the Australian Manufacturing Workers’ Union, (AMWU), highlights a reality many organisations face in evolving safety programs in a way that is both legally sound and operationally practical.
The Background – Policy Under Review
Opal Packaging sought to modernise its AOD policy following disruptions and inconsistencies experienced across its sites. Key proposed changes included:
- Moving from blanket testing of all workers at certain sites to random sampling
- Removing self-testing breathalyser units
- Eliminating provisions that allowed workers to self-exclude after a positive test
- Tightening controls around prescription and over-the-counter (OTC) medication disclosures
The goal was clear – reduce operational disruption while maintaining a robust safety framework.
The Dispute – Consultation & Compliance
The union challenged these changes on two main grounds:
- Insufficient consultation with workers
- Alleged breach of the enterprise agreement
Initially, the Fair Work Commission sided with the union, finding that Opal Packaging had not provided all relevant information about the rationale behind the changes. However, the matter escalated to the Federal Court – where the decision ultimately shifted.
The Outcome – Employer Rights Clarified
The Federal Court found that:
- The enterprise agreement did not prescribe a specific testing method
- Opal Packaging had not breached the agreement by introducing random sampling
In essence, the Court confirmed that if a workplace agreement does not explicitly restrict how testing is conducted, employers retain flexibility to adapt their approach.
Key Takeaways
- Drug & Alcohol policies sit at the intersection of risk and rights
Changes (particularly those involving testing and monitoring) will always attract scrutiny. - Clarity in agreements is critical
Ambiguity can leave room for interpretation, often favouring employers where changes remain consistent with the broader intent. - Consultation is a safeguard, not a formality
Even though Opal Packaging ultimately succeeded, the earlier ruling highlights the importance of genuine consultation – clearly communicating the why behind changes. - Random sampling, when implemented correctly, can:
Maintain a stronger deterrent effect, reduce operational downtime and be legally defensible. - Clarification from the Court
Random sampling is acceptable, unless an agreement specifically mandates otherwise. This is a significant point for organisations reviewing their AOD frameworks.
What This Means for Your Workplace
For organisations managing drug and alcohol safety programs, this case offers a timely reminder:
- Review your enterprise agreements – understand what is (and isn’t) prescribed
- Document your safety rationale clearly – especially when making changes
- Engage early with your workforce – consultation reduces both risk and resistance
- Design practical, scalable drug and alcohol testing models – not all sites require the same approach
Most importantly, it reinforces that effective AOD programs are not static and must evolve alongside:
- Operational realities
- Workforce expectations
- Legal frameworks
This doesn’t just affirm an employer’s right to adapt; it underscores the importance of doing so strategically, transparently, and with safety at the centre.
Critical Consideration – Self-Testing Breathalysers
While the case supports flexibility in testing models, one proposed change (removing self-testing breathalyser units) raises important safety considerations.
Retaining self-testing breathalyser plays a valuable role in proactive risk management and fostering a culture of accountability including:
- Objective data over guesswork
Alcohol affects individuals differently based on fatigue, food intake, and metabolism. Self-testing replaces unreliable assumptions with precise, scientific measurement—enabling informed decisions before risk occurs. - Proactive risk mitigation
Removing self-testing eliminates a frontline control. Retaining it demonstrates a commitment to harm reduction and due diligence, potentially reducing liability exposure. - A visible deterrent
The presence of a breathalyser reinforces workplace expectations. Seeing an actual Breath Alcohol Concentration (%BrAC) provides a clear, immediate reality check.
Removing self-testing breathalysers doesn’t eliminate alcohol-related risk – it removes a practical tool for managing it. Without these units, organisations rely more heavily on detection after the fact rather than prevention beforehand. This can shift a safety program from proactive to reactive.

The Federal Court decision reinforces that effective AOD programs require balance – between enforcement and prevention, flexibility and compliance. The strongest programs are those that not only detect risk, but actively help prevent it – building workplaces where safety is embedded, behaviour is informed, and operations continue with confidence.
