The cost of psychological injury claims in Australia
Luke Giuseppin
A single serious psychological injury claim in New South Wales now costs $288,542 on average. That figure has nearly doubled in five years, and it is the number most Australian employers cannot produce when a CFO, auditor, or board member asks what a psychological injury actually costs the organisation. The cost is not hidden. It is in the workers' compensation data, the premium schedule, and the productivity of the workforce that carries the claim's absence. The gap is that it is rarely measured, and the gap between what is being paid and what is being understood is the defining feature of the cost of psychosocial claims in Australia today.
This page sets out what psychological injury claims actually cost Australian employers, drawing on Safe Work Australia's Key Work Health and Safety Statistics and scheme-specific data. It covers the single-claim cost and its trajectory, the disproportionality between claim volume and claim cost, the multipliers that sit underneath that disproportionality, the hazard categories driving the claims, the industry patterns that rewrite the national average, and the premium trajectory that turns a single claim into a five-year cost. It closes with where prevention sits in the picture, and where to start. For the wider cost picture beyond claims, see the cost of psychosocial non-compliance.
The single-claim cost: $288,542, and rising
The most-cited claim cost figure in Australia is the NSW average. A serious psychological injury claim in NSW cost $288,542 on average in 2024-25, per NSW Workers' Compensation Parliamentary Inquiry data cited by the NSW Treasurer. That figure has risen from approximately $146,000 in 2019-20. The near-doubling over five years is the trajectory that matters more than any single figure, because it tells a prospective buyer of workers' compensation cover, or a CFO modelling forward, that the cost base is not stabilising.
Nationally, the median compensation for a mental health claim is $67,400, per Safe Work Australia's 2023-24 Key Work Health and Safety Statistics. The NSW average is higher because the NSW scheme settles a greater share of claims at the upper end, but the direction of travel is the same across every state scheme: claim costs have moved from a middle-five-figure range to a low-six-figure range within the past decade.
The aggregate tells the same story. The total national cost of mental injury workers' compensation claims crossed $1 billion in 2024-25. That threshold was projected by Committee for Economic Development of Australia modelling to arrive in 2030. It arrived five years early.
The disproportionality: 12% of volume, 38% of cost
The single statistic that resets the conversation for CFOs and finance committees is the gap between how often psychological claims occur and how much of the system's cost they consume.
Mental health claims represent 12% of all serious workers' compensation claims in Australia. They represent 38% of total compensation costs. That is a roughly threefold disproportionality in a single category. If psychological injury were costed at the same rate as physical injury, its share of the system would match its volume, but it does not. The 26-point gap between the claim share and the cost share is the measurable expression of why psychological injury is now the dominant financial risk in the Australian workers' compensation system. It is also the stat the NSW Treasurer referenced when warning that the scheme would collapse under the rising toll of workplace psychological injuries, and it is visible across every state scheme where the data has been broken out.
Why the cost is higher: four measurable multipliers
The disproportionality is not arbitrary. Four measurable gaps between psychological and physical injury explain it, and each sits in the Safe Work Australia data.
Claim cost. Psychological injury claims cost approximately four to five times more than physical injury claims on a per-claim basis. The median national compensation for a mental health claim is $67,400, compared with $14,600 to $17,600 across physical claim categories.
Time off work. The median time off work for a psychological injury claim is 35.7 weeks, compared with 7.2 to 7.7 weeks for physical injury. That is a near fivefold multiplier in claim duration, and because claim cost scales with duration, it feeds directly into the cost multiplier above.
Time to resolve. Average time to resolve a psychological injury claim runs roughly five times the physical injury benchmark. That means more medical assessments, more disputed elements, more case-management time, and more insurer administration per claim.
Return to work. Only 50% of workers with a psychological injury return to work within twelve months, compared with 95% for physical injury. For the employer, that means a single psychological claim is roughly twice as likely to end in a separation rather than a return. The recruitment and replacement cost that follows a non-return sits outside the workers' compensation system entirely, and it compounds on top of the claim cost itself.
The 50% versus 95% gap is the most important stat for HR and people leaders. It connects the financial argument to the human argument. A psychological injury is not only more expensive to process, it is materially more likely to end a career with the employer, and the cost of that outcome is absorbed by the organisation through recruitment, onboarding, and ramp time long after the claim itself has closed.
What is driving the claims: the hazard mix
Safe Work Australia's breakdown of mental stress claims identifies three dominant causes across the sample. The exact shares move slightly year to year as the Key Work Health and Safety Statistics methodology evolves, but the ordering has been consistent for several reporting periods.
Harassment and workplace bullying account for 27.5% to 33.2% of mental stress claims.
Work pressure accounts for a further 25.2%.
Workplace violence accounts for 16.4%.
Between them, those three categories explain roughly 70% of the mental stress claim volume in Australia. Each maps directly to a hazard category named in the Managing Psychosocial Hazards at Work Code of Practice, which means the causes are not novel, unobservable, or unmanageable. They are defined hazards with specific control frameworks that regulators now expect PCBUs to be using, and an organisation that can demonstrate active management of bullying, work pressure, and violence is addressing the drivers that produce the majority of its claim exposure. The full 17-category hazard framework under the Commonwealth Code of Practice 2024 sets out the rest.
Industry patterns that rewrite the national average
The national average hides significant industry variation, and that variation changes the cost picture for any employer assessing its own exposure against the benchmark.
Healthcare and social assistance records the highest volume of psychological injury claims of any industry in Australia. The sector accounted for 19.9% of all serious claims nationally in 2023-24, and the mental health share within healthcare is believed to be materially higher than the 12% national average. Drivers include trauma exposure, chronic understaffing, high emotional demands, shift-based fatigue, and violence from patients. In NSW specifically, healthcare alone accounts for 20% of all psychosocial complaints received by SafeWork NSW.
Education and training sits among the highest-risk industries. Tertiary education workers report significantly lower psychosocial safety climate scores than the general working population. Common claim triggers include unreasonable workload, harassment and bullying, exposure to aggression from students or parents, poor organisational change management during restructuring, and lack of role clarity across multiple campuses or partnerships. Education accounts for 12% of NSW psychosocial complaints.
Accommodation, food, and hospitality carries a disproportionately high rate of psychological distress: 44% of hospitality workers report the job negatively affects their mental health, and roughly one in three experience high to severe psychological distress (approximately double the national average). Despite that, psychological injury claims in hospitality account for less than 1% of accepted claims in the sector. The gap indicates widespread under-claiming, not low risk. A compliance posture built around observed claim volume will systematically understate the actual hazard profile in these workplaces.
Public administration, emergency services, construction, and farming each carry elevated and partly distinct claim profiles. Cumulative trauma in emergency services and corrections. Elevated suicide risk in construction and farming, combined with job insecurity and low help-seeking culture. Claim rates in these sectors are under-represented in aggregate data because the mechanisms driving them are not fully captured by standard workers' compensation reporting, particularly for owner-operators and contractors outside standard coverage.
Professional services (including financial services, legal, consulting, engineering consulting, and architecture) carries lower absolute claim volume but the fastest-growing mental health share of total claims within the category. Drivers include high job demands, long-hours culture, remote monitoring and surveillance hazards, and poor work-life boundaries. For any employer in this bracket, the relevant baseline is not the national average; it is the sector's own trajectory, which is accelerating.
The premium trajectory: the cost that keeps appearing for five years
A workers' compensation premium is a lagging indicator. It reflects claim experience over a multi-year window, which means a single serious psychological claim can lift premium loadings for three to five subsequent years in most state schemes.
The cost of a claim, in other words, is not confined to the claim payout. It is the payout plus several years of elevated premium exposure, plus reduced bargaining position with workers' compensation insurers at renewal, plus the recruitment and replacement cost that follows the worker who did not return to work, plus the operational disruption during an extended absence of 35.7 weeks on average. For an organisation running at even one or two serious psychological injury claims per year, the compounded premium impact is material. It is also invisible on most financial dashboards until the premium schedule lands each year, which is one of the reasons the full cost is chronically under-modelled.
The picture for any Australian employer today
Pulled together, the cost of psychosocial claims in Australia looks like this.
A single serious claim costs approximately $288,542 in NSW, or a median $67,400 nationally. Claim volume has risen 161% over the past decade, with 17,600 mental health claims lodged in 2023-24 alone. The aggregate cost crossed $1 billion five years ahead of projection. Mental health claims account for 12% of claim volume but 38% of system cost, driven by a four to fivefold cost multiplier, a near fivefold duration multiplier, and a return-to-work rate half that of physical injury. Harassment, bullying, work pressure, and violence drive roughly 70% of the claim volume. Healthcare and education carry disproportionate exposure, hospitality under-claims against actual risk, and professional services is the fastest-accelerating category. A single claim typically feeds premium exposure for three to five subsequent policy years. Sitting alongside the claims picture is the personal exposure officers carry when controls fail, and the operational cost of running compliance manually.
Every number in that picture is moving in the same direction: up. No trend line points toward stabilisation, and no regulatory change in the past three years has moved in the opposite direction.
Where prevention sits in this picture
The cost of psychosocial claims is avoidable in a way that most other categories of workers' compensation cost are not. Physical injury claims often flow from hazards intrinsic to the work itself. Psychological injury claims flow from hazards that are identifiable, measurable, and controllable, and the Managing Psychosocial Hazards at Work Code of Practice has set out the methodology for doing that work. Organisations systematically identifying psychosocial hazards, assessing severity, implementing controls aligned to the hierarchy, and reviewing control effectiveness are producing a different claims trajectory from those that are not. The gap between the two groups is widening each year. The Psychosocial Compliance Internal Audit Checklist is a starting point for assessing where the organisation currently sits.
ReFresh's psychosocial compliance platform produces the systematic evidence layer that a well-managed claims exposure requires: a current hazard register, documented risk assessments, controls mapped to the hierarchy, and a review cadence that a regulator, auditor, or insurer can inspect. For the full regulatory context, the starting point is our pillar guide to psychosocial compliance in Australia. The broader cost picture for the organisation is covered in our pages on the cost of psychosocial non-compliance and the cost of officer liability. Jurisdiction-specific regulatory detail sits on the New South Wales, Victoria, Queensland, Western Australia, and Commonwealth reference pages.
Understand where your claim exposure sits
Most Australian organisations cannot describe their current psychosocial claim exposure with any precision, because the relevant data sits across the insurer's system, the HR system, and the WHS system, and it is rarely pulled together. A 5-minute psychosocial compliance readiness survey will give your leadership team a structured view of where the main exposure concentrations sit and where the first operational moves should land. If a conversation is more useful, Luke runs 20-minute operational walkthroughs of the current claims and compliance picture: no pitch, just a structured look at where the cost is accruing and what would change it.
