Workers Compensation for Mental Health: Can I Claim for Stress and Anxiety? (2026)
Yes, you can claim workers compensation for mental health conditions in Australia — but the rules are strict. Learn the 'significant contributing factor' test, state-by-state thresholds, evidence required, provisional liability, and your rights if your employer disputes the claim.
Can you claim workers comp for stress, anxiety, or depression?
Yes, Australian workers compensation schemes cover psychological injuries — including stress, anxiety, depression, post-traumatic stress disorder (PTSD), and adjustment disorders — where the injury arises out of or in the course of employment. However, psychological injury claims face a higher threshold than physical injury claims in every state and territory. The general requirement is that employment must be a 'significant contributing factor' to the psychological injury, rather than simply 'a contributing factor' as required for physical injuries. This higher bar exists because lawmakers recognised that people experience stress from many sources — personal relationships, financial pressure, health issues — and the workers compensation system is only designed to cover injuries substantially caused by work. The most common work-related psychological injuries involve exposure to traumatic events (emergency workers, healthcare staff), sustained workplace bullying or harassment, excessive workload and unreasonable management demands, organisational change causing chronic uncertainty, and secondary trauma from handling distressing material. Claims for psychological injury have increased substantially in recent years, accounting for approximately 9% of all serious claims but over 30% of total workers compensation costs because of their longer duration and higher treatment costs.
The 'reasonable management action' exclusion you need to know about
Every state and territory workers compensation scheme excludes psychological injuries that arise wholly or predominantly from reasonable management action taken in a reasonable manner. This is the most common reason psychological injury claims are denied. The exclusion covers the same types of management action discussed in bullying law: performance management, disciplinary processes, restructuring, roster changes, transfers, demotion for valid reasons, and termination for genuine operational or performance reasons. In NSW under s11A of the Workers Compensation Act 1987, if an employer can establish that the injury was wholly or predominantly caused by reasonable management action carried out in a reasonable manner, the claim will be rejected. In Victoria under s40 of the Workplace Injury Rehabilitation and Compensation Act 2013, the exclusion applies where employment was not the predominant cause or the injury arose from reasonable management action. Queensland's Workers Compensation and Rehabilitation Act 2003 has a similar exclusion under s32. The critical distinction is between management action that follows proper processes and management action that is carried out unreasonably — for example, publicly humiliating an employee during a performance review, or conducting a sham investigation designed to build a case for termination.
State-by-state differences in psychological injury thresholds
While all states require a stronger employment connection for psychological injuries, the precise tests differ. In NSW, employment must be the 'main contributing factor' to the injury (Workers Compensation Act 1987 s11A) — the toughest test in the country following 2023 amendments. In Victoria, employment must be the 'predominant' cause (WIRCA 2013 s40), and the worker must have a degree of permanent impairment of at least 30% for common law damages (one of the highest thresholds). In Queensland, employment must be the 'major significant contributing factor' (WCRA 2003 s32). In South Australia, employment must be 'the significant contributing cause' (Return to Work Act 2014 s7). In Western Australia, employment must be a 'significant contributing factor' (Workers Compensation and Injury Management Act 1981 s5). In Tasmania, employment must be 'a significant contributing factor' (Workers Rehabilitation and Compensation Act 1988 s25). The ACT and NT follow the Comcare scheme, where employment must be a 'significant contributing factor.' These differences matter because the same set of facts could succeed in one jurisdiction and fail in another. Workers in NSW face the hardest test, while those in Tasmania and the ACT have a somewhat lower threshold.
What evidence do you need for a psychological injury claim?
A successful psychological injury claim requires strong medical and workplace evidence. You will need a report from a treating doctor (GP or psychiatrist) diagnosing a recognised psychological condition (typically using DSM-5 or ICD-11 criteria) and stating that employment was a significant (or main, or predominant, depending on your state) contributing factor. Treatment records from psychologists, counsellors, or Employee Assistance Programs (EAPs) strengthen your case. Your insurer will almost certainly arrange an Independent Medical Examination (IME) with a psychiatrist of their choosing — the IME report often determines the outcome, so being thorough and honest in that assessment is vital. Beyond medical evidence, you need workplace evidence: incident reports, emails documenting bullying or excessive demands, formal complaints you have made, witness statements from colleagues, performance reviews (especially if they show a sudden change correlating with the onset of the hazard), and any records showing you raised concerns with management or HR. If your claim relates to a traumatic event (witnessing an accident, being assaulted), incident reports and police reports are important. A timeline showing the progression from exposure to symptoms to diagnosis is particularly persuasive.
Provisional liability: your employer must start paying quickly
One of the most important protections for injured workers is provisional liability, which requires the insurer to start paying weekly benefits and reasonable medical expenses before the claim is fully determined. In NSW, provisional liability must commence within 7 calendar days of the claim being made and lasts for up to 12 weeks. In Victoria, the insurer has 28 days to accept or reject the claim, but must pay weekly benefits during that period. In Queensland, the insurer has 20 business days to decide, with provisional payments in the interim. This means that even if your psychological injury claim is ultimately disputed, you should receive income support and funding for treatment in the early weeks. Provisional liability applies to psychological injuries just as it does to physical injuries. If your employer or their insurer fails to commence provisional liability within the required timeframe, contact your state regulator (e.g., SIRA in NSW, WorkSafe in Victoria, WorkCover Queensland). During the provisional period, you should be receiving your normal weekly earnings (subject to step-downs that apply later). Use this time to engage with treatment, gather evidence, and obtain a detailed report from your treating practitioner.
Stigma and your rights during a mental health claim
Workers with psychological injuries often face stigma that workers with physical injuries do not. Colleagues may question the legitimacy of the claim, managers may treat the worker differently, and the adversarial claims process itself can worsen the injury. It is important to know your rights. Your employer cannot terminate you solely because you have made a workers compensation claim — doing so is discriminatory conduct under WHS legislation and may also constitute adverse action under the general protections provisions of the Fair Work Act (s340-342). In most states, you cannot be dismissed while receiving weekly workers compensation payments for the first six months (in NSW, this period is six months from the date of injury under s248 of the Workplace Injury Rehabilitation and Compensation Act). Your medical information is confidential and your employer is only entitled to receive information relevant to the claim and your capacity to work. You do not have to disclose your diagnosis to colleagues. If you experience retaliation, document it and report it to your insurer, your union, or the relevant regulator. Many workers find that engaging a lawyer who specialises in workers compensation helps navigate the process, and most workers compensation lawyers operate on a no-win-no-fee basis for initial consultations.
Practical steps if you are considering a claim
If your mental health has been affected by work, take these steps. First, see your GP and be honest about how work is contributing to your condition — ask for a referral to a psychologist or psychiatrist and request a workers compensation medical certificate if your doctor agrees the injury is work-related. Second, notify your employer in writing that you are making a workers compensation claim — most states require notification within specified timeframes (e.g., 6 months in NSW, but as soon as practicable is best practice). Third, complete the workers compensation claim form for your state (available from your employer's insurer or your state regulator's website). Fourth, gather and preserve evidence: emails, incident reports, diary entries, text messages, and the names of potential witnesses. Fifth, engage with the insurer's process — attend the IME, respond to reasonable requests for information, and continue with treatment. Sixth, consider getting legal advice early, especially if your claim is disputed. Workers compensation lawyers can assess the strength of your claim, negotiate with the insurer, and represent you at any conciliation or hearing. Finally, lean on support networks: your GP, your psychologist, your union, and trusted friends or family members.
