Overview
PTSD can be a NSW workers compensation injury, but the dispute is usually about proof, not labels
What you need to know: PTSD may be compensable, but the legal test depends on the notification date, whether the condition is primary or secondary, the worker category and the event relied upon. A diagnosis or distress after an event does not establish liability by itself.
For a primary psychological injury first notified on or after 1 July 2026, PTSD must arise from one or more statutory relevant events, such as an act or threat of violence, indictable criminal conduct, qualifying traumatic witnessing, vicarious trauma or a qualifying death in the worker’s immediate and primary care. The evidence must also establish a real and direct employment connection and employment as the main contributing factor. Earlier and secondary claims use different rules. Insurers may also dispute diagnosis, competing causes, treatment, capacity or section 11A.
The safest early response is to build a dated evidence trail: what happened at work, when symptoms started, what treatment was needed, how capacity changed, and why any insurer medical examination misses important context. This page is general information only, and PTSD claims should be checked against your own medical evidence, insurer notices, and time limits.
This is general information, not legal advice, and it is not a substitute for advice about your own diagnosis, work history, insurer correspondence, and limitation position.
Which psychological-injury rules apply?
Law reviewed 2026-07-21
The new primary psychological injury rules apply where the employer first received notification of the injury on or after 1 July 2026. A primary psychological injury notified before that date continues under the earlier provisions. The amendments also do not apply in the same way to secondary psychological injuries, exempt workers such as police officers, paramedics and firefighters, coal miners, volunteers or dust-disease claims. The notification history, worker category and transitional provisions must be checked before choosing a legal test.
New primary psychological injury
For a primary psychological injury within the post-1 July 2026 framework, the claimed condition must be a mental or psychiatric disorder causing behavioural, cognitive or psychological dysfunction. Compensation is only payable if one or more statutory relevant events caused the injury, there is a real and direct connection between those events and the employment, and employment is the main contributing factor.
Bullying, sexual harassment, racial harassment and excessive work demands are “relevant conduct”. A post-1 July 2026 primary psychological injury caused by relevant conduct uses a special claim process. A completed claim form and prescribed minimum information are required; the insurer has 42 days after receiving a completed claim to decide liability. Interim weekly payments and up to $7,500 for eligible outpatient treatment may be available during that determination period. Provisional liability does not apply to this special claim type. If liability remains disputed, the insurer review and the correct IRC or PIC pathway depend on the stated reason for the decision.
Section 11A and earlier claims
For a claim to which the amended section 11A applies, no compensation is payable if the psychological injury was predominantly caused by reasonable management action taken or proposed by the employer, the worker's expectation of reasonable management action, or the worker's perception of reasonable management action. The action must be taken in a reasonable way and be reasonable in all the circumstances. The amended provision applies to both primary and secondary psychological injury.
For an earlier psychological injury claim governed by the pre-reform section 11A, the question was whether the injury was wholly or predominantly caused by specified reasonable action taken or proposed by or on behalf of the employer concerning matters such as transfer, demotion, promotion, performance appraisal, discipline, retrenchment, dismissal or employment benefits. The action and the way it was taken also had to be reasonable.
What the insurer should examine in a PTSD claim
- The decision should address all relevant evidence; a single insurer opinion is not automatically decisive.
- Timeline clarity matters: incident pattern, symptom onset, treatment progression, and work impact.
- The statutory event, notification-date framework, section 11A reasoning and work-capacity evidence must be analysed separately.
Where PTSD claims usually come unstuck
PTSD claims are rarely straightforward. Insurers often accept that a worker is distressed but dispute whether the diagnosed condition is compensable under NSW legislation. The case can then pivot to section 11A, “reasonable action” arguments, and selective reliance on independent examination reports.
If your claim has already been declined or narrowed, cross-check this page with the section 11A guide, claim denied pathway, and PIC disputes process.
What usually goes wrong before a PTSD dispute escalates
1. Section 11A is not challenged early
Workers focus on symptoms only, while the insurer builds a legal narrative around reasonable managerial action.
2. Capacity records drift apart
Inconsistent certificates and vague restrictions create openings for payment reductions and unsuitable work proposals.
3. Treatment denials are treated as separate issues
Refused psychology or psychiatry treatment can weaken ongoing causation and capacity evidence if not disputed quickly.
4. IME reports set the narrative
A single adverse exam often drives denial, work-capacity cuts, and delay unless treating evidence directly addresses it.
Evidence checklist for psychological injury disputes
- Initial incident/exposure records and chronology of symptom onset.
- GP and psychiatrist notes that clearly address diagnosis, causation, and work-related contribution.
- Certificates of Capacity with practical functional limits and treatment plan continuity.
- Section 78 notices, denial letters, and any section 11A reasoning relied on by the insurer.
- IME reports plus documents needed to challenge inaccuracies or missing context.
A useful chronology is usually more specific than a general statement that work caused stress. It should identify the work events or exposure pattern, who was involved, what records exist, when symptoms became clinically significant, when treatment began, how duties or hours changed, and how the condition affected ordinary work capacity. If there are non-work stressors, the evidence should address them honestly rather than ignoring them, because insurers often rely on gaps or competing explanations.
How PTSD evidence links to payments, treatment, and disputes
Weekly payments and capacity
Weekly payments usually depend on accepted incapacity, certificates of capacity, and any work-capacity decision. In a PTSD claim, vague restrictions such as “unfit due to stress” may be vulnerable if they do not explain functional limits, triggers, medication effects, treatment frequency, and why proposed duties are or are not suitable.
Treatment approvals
Psychology, psychiatry, medication reviews, and graded return-to-work support may need to be connected to the accepted work injury and described as reasonably necessary. If treatment is refused, the dispute should usually address both clinical need and why delay may worsen capacity or recovery.
Permanent impairment, PIRS and sources
PTSD may also raise permanent impairment, whole person impairment (WPI), and section 66 lump sum questions once the condition is sufficiently stable for assessment. Section 65A requires at least 15% WPI for permanent impairment compensation for a primary psychological injury. No permanent impairment compensation is payable for a secondary psychological injury, and secondary psychological symptoms are excluded from a physical or primary psychological impairment assessment. A diagnosis does not establish the threshold.
NSW uses the Psychiatric Impairment Rating Scale (PIRS) for primary psychological injury. The six functional areas are self-care and personal hygiene; social and recreational activities; travel; social functioning and relationships; concentration, persistence and pace; and employability. The median class and aggregate score are used under the NSW method. A PTSD diagnosis does not produce a fixed WPI result, and secondary psychological impairment associated with a physical injury is not assessed as WPI.
PIRS table illustration
If supported domain classes are 1, 2, 2, 3, 3 and 4, the two middle values average to 2.5 and round up to median Class 3. Their aggregate is 15, which NSW Table 11.7 maps to 15% WPI. The calculation cannot be used until each class is supported by the person's stable functional evidence.

Section 78 and section 11A notices
A section 78 notice may deny liability, dispute causation, or rely on section 11A. Read the stated reasons carefully. Evidence should answer the exact reason given, not just repeat that symptoms are severe. The response may need workplace documents, treating reports, and a clear explanation of why the insurer’s characterisation is incomplete.
IME and PIC preparation
If an independent medical examination (IME) report is adverse, compare it with the treating history before assuming it is final. Look for missing documents, incorrect timelines, unsupported capacity assumptions, or failure to engage with the worker’s actual duties. Some disputes may then need preparation for the Personal Injury Commission (PIC).
For related next steps, see the guides on weekly payments stopped, work-capacity decisions, unfair IME reports, and section 78 notices.
A practical process for PTSD claim pressure
1. Separate medical proof from legal issues
Confirm the diagnosis, treatment plan, and functional restrictions first. Then identify the legal reason the insurer is using, such as causation, section 11A, reasonable and necessary treatment, or work capacity.
2. Match evidence to the insurer notice
A section 78 notice, treatment denial, or work-capacity decision should be answered point by point. General statements of distress are rarely enough if the insurer has relied on a detailed IME report or workplace chronology.
3. Protect weekly payments and treatment together
Treatment denials, suitable employment assumptions, and reduced certificates can interact. Keep your GP, psychologist, psychiatrist, and lawyer aligned so capacity evidence supports the dispute pathway.
If a decision has already been made, do not assume the next step is the same for every PTSD claim. Some matters need internal review evidence first, some need urgent weekly payment strategy, and some are better prepared for the Personal Injury Commission (PIC). Time limits can apply, so get advice before waiting for the insurer to reconsider informally.
FAQs
Can I claim workers compensation for PTSD in NSW?
PTSD may be compensable, but a diagnosis is not enough. For a primary psychological injury first notified on or after 1 July 2026, the evidence must establish a statutory relevant event, a real and direct connection with employment and employment as the main contributing factor. Earlier, excluded and secondary claims use different provisions.
What is section 11A and why does it matter in PTSD claims?
For a claim governed by amended section 11A, no compensation is payable if the injury was predominantly caused by reasonable management action taken or proposed, or by the worker’s expectation or perception of it. The action must be reasonable in all the circumstances and taken in a reasonable way. Earlier claims may use the former wholly-or-predominantly-caused test.
Do PTSD claims affect weekly payments and work-capacity decisions?
They can. Even where liability is accepted, weekly payments depend on incapacity and the applicable weekly-payment rules. Certificates and treating reports should explain sustainable attendance, concentration, triggers, interaction, medication effects and why proposed duties are or are not suitable.
What evidence helps with a PTSD workers compensation dispute?
Useful evidence usually includes a clear diagnosis, a chronology of work events or exposures, GP and psychiatrist records, certificates of capacity, treatment plans, insurer notices, and a careful response to any IME opinion or section 11A reasoning.
Should I wait before disputing a PTSD claim denial?
Do not ignore a written decision. Different notices and proceedings have different review or filing requirements, and relevant-conduct claims may require insurer internal review before the correct IRC or PIC step. Prompt advice can identify the actual deadline and evidence needed without assuming one universal time limit.
