Psychosocial safety and the role of mediation: prevention is now the legal standard

Every Australian jurisdiction now has formal regulations requiring employers to prevent psychological harm at work. Mediation is one of the most underused tools in that prevention toolkit. This article is here to help employers understand when mediation is the right intervention, how it should be used, and who is qualified to facilitate it.

The duty has shifted from response to prevention

From 1 December 2025, Victorian employers have a positive duty under the Occupational Health and Safety (Psychological Health) Regulations 2025 to proactively identify, assess, control, review and consult on psychosocial hazards. The same structured approach that has long applied to physical safety risks now applies to psychological ones.

Sitting alongside this is the federal Respect@Work positive duty under the Sex Discrimination Act, which applies in every state and territory. Employers must take reasonable and proportionate measures to eliminate sexual harassment, sex-based harassment, hostile work environments and victimisation.

Regulators are no longer asking whether an employer responded well after harm occurred. They are asking what the employer did to prevent foreseeable harm in the first place.

This is now a national picture

With Victoria’s regulations commencing in December 2025, every Australian jurisdiction now has formal psychosocial hazard regulations in place. The detail differs, but the direction is consistent: employers must identify and control psychosocial risks, with documented evidence of how they have done so.

For employers operating in more than one state, compliance now means meeting both the harmonised model provisions and the jurisdiction-specific variations and for Victorian employers, an entirely separate framework that runs in parallel.

Conflict and incivility are named psychosocial hazards

It is easy to read the headlines and assume psychosocial safety law is mostly about bullying, sexual harassment and violence. Those are serious hazards, but they sit at the more extreme end of a wider list.

The regulations and supporting codes across Australia recognise that psychosocial hazards also include:

• unresolved interpersonal conflict and workplace incivility
• poor work design, unclear roles and conflicting expectations
• sustained workload pressure and unrealistic demands
• inconsistent or low-quality management practices
• exclusion, isolation or breakdown of working relationships

For most workplaces, these everyday hazards are where harm starts. They are also where mediation has the strongest evidence base.

The hierarchy of controls applies — but the hazards are often people

The hierarchy of controls is the framework that has guided Australian workplace safety for decades. It ranks risk control measures from most to least effective:

1. Eliminate the hazard
2. Substitute it with something safer
3. Engineering controls — isolate the hazard from people
4. Administrative controls — policies, procedures, training, supervision
5. Personal protective equipment

Most safety practitioners have applied this model for years. It is now expressly required for psychosocial risks in New South Wales, Queensland, South Australia, the ACT, the Northern Territory and the Commonwealth. Victoria has not adopted the language formally, but the conceptual approach still applies — and regulators expect to see higher-order controls considered before lower-order ones.

The difference, and the challenge, is that in a psychosocial matter the “hazard” is rarely an unguarded machine or a toxic chemical. It is more often a person, a relationship, a team dynamic, or a way of working that has gone wrong. That makes elimination and substitution harder, but not impossible.

An EAP helps the individual cope with the hazard. Mediation can change the hazard itself — the relationship, the misunderstanding, the pattern of behaviour. That is what makes it a higher-order intervention rather than a wellbeing add-on.

Mediation is not the same as a facilitated discussion

When a manager or HR officer sits two staff members down to talk through a problem, that is a facilitated discussion or internal conflict coaching. It can be useful — but it is not mediation.

Mediation is a specific professional process. In Australia, the national benchmark is set by the Australian Mediator and Dispute Resolution Accreditation Standards (AMDRAS), which replaced the National Mediator Accreditation System (NMAS) on 1 July 2025. An AMDRAS Accredited Mediator:

• is independent of all parties and impartial in their faciliation
• has completed accredited mediation training and assessment
• is bound by the AMDRAS Practice Standards, including confidentiality, neutrality and informed consent obligations
• must meet Continuing Professional Development obligations each year
• is subject to a complaints process through their Recognised Accreditation Provider
• carries appropriate professional indemnity insurance

For psychosocial safety purposes, the distinction matters in three ways.

Independence

When the person leading the conversation is the supervisor, HR business partner or colleague of one or both parties, the process is not impartial. It can later be challenged as biased, coercive or part of the very system that contributed to the harm. An external accredited mediator removes that risk.

Higher-order control

Regulators have been explicit that policies, training and EAPs are lower-order administrative controls and are not, on their own, adequate where higher-order options are reasonably practicable. Engaging an independent accredited mediator to address a known interpersonal or team-level risk is a higher-order intervention — a documented change to how a specific risk is being managed.

Evidence of due diligence

An Agreement to Mediate, signed by all parties, and the records of any agreements reached provide concrete evidence of what control was implemented, when, and how. A file note from an internal HR meeting carries far less evidential weight if a matter ever reaches WorkSafe, the Fair Work Commission, the Australian Human Rights Commission or a court.

Mediation and internal facilitation are different tools. Each has its proper use. Where the matter calls for external, impartial intervention, AMDRAS accreditation is what gives the process its integrity.

You can verify the accreditation status of any mediator on the National Register of Registered Practitioners on the AMDRAS website.

Where mediation fits in a prevention system

Done well, mediation can de-escalate matters that would otherwise become formal grievances, WorkCover claims or resignations. In a psychosocial safety system, it can be used at several points.

Early intervention

When two team members are in sustained conflict, when a working relationship has broken down, or when a team is functioning poorly, a workplace mediator can address the issue before it becomes a complaint, a stress claim or a regulator notice. This is the most cost-effective use of mediation and the one most aligned with the prevention duty.

Restorative work after an investigation

Where a formal complaint has been investigated and substantiated, the team is often left with damaged relationships and lingering distrust. A mediator with experience in restorative practice can help rebuild a workable culture, with appropriate safeguards.

Change and transition support

Restructures, mergers and significant operational change are well-recognised psychosocial risks. Group facilitation and mediation can surface and resolve issues that would otherwise embed as long-term cultural problems.

Manager and team capability building

Conflict coaching and short courses for managers — drawing on mediation skills — help leaders deal with everyday workplace tension before it escalates. This addresses the regulators’ clear expectation that supervision and leadership capability are part of the control framework, not just policies and training.

Where mediation is not the right tool

The recent Federal Court decision in Magar v Khan [2025] FCA 874 is instructive. The Court awarded $305,000 in damages in a matter involving sexualised conduct, a significant power imbalance, and a culture that tolerated the behaviour. Cases like that need investigation, accountability and structural change — not a meeting with a mediator.

Skilled workplace mediators screen carefully for these factors before agreeing to mediate, and refer matters elsewhere when mediation is not the right intervention. That assessment is part of the professional standard.

What employers should be doing now

Wherever your business operates in Australia, the direction of regulation is the same. Practical steps include:

1. Identify psychosocial hazards in your workplace, with input from staff and health and safety representatives. Workplace conflict, unclear roles and management practice are common findings.
2. Build mediation and conflict resolution into your control framework — not as a substitute for investigation, but as a documented option for the matters where it fits.
3. Train managers and HR staff in conflict resolution skills so they can address everyday tension early.
4. Keep records that show what risks were identified, what controls were chosen and why, and how they were reviewed. The compliance benchmark is evidence of a proportionate, risk-based approach — not a paper policy.
5. Engage AMDRAS Accredited Mediators for matters that warrant external, impartial intervention — and verify accreditation on the National Register.
