Workers compensation claim deadline in NSW
In NSW, a worker must give notice of a workplace injury to the employer as soon as possible after the injury occurs, and lodge a workers compensation claim within six months of the injury date (section 261 Workplace Injury Management and Workers Compensation Act 1998 (NSW)). Late claims can still be accepted if the worker had a reasonable cause for the delay and the insurer is not prejudiced. However, the six-month deadline should be treated as firm — late claims face additional scrutiny and may be rejected.
Notice and claim deadlines
Notice to the employer: as soon as practicable after injury. Formal claim to the insurer: within six months of the injury date (or date of incapacity for gradual-onset injuries). The employer must forward the claim to their insurer within seven days of receiving it. The insurer then has 21 days to accept or decline (or request more information).
Late claims
Claims lodged after six months can be accepted under section 261(4) if the worker shows a reasonable cause for the delay (e.g., the worker did not realise the injury was work-related, or the injury was gradual onset) and the insurer or employer is not materially prejudiced by the delay. Prejudice typically means loss of evidence or inability to investigate.
How I help with workers compensation deadlines
I track claim deadlines for personal injury practices — flagging matters approaching the six-month limit. I also draft workers compensation claims and supporting medical evidence summaries, ensuring the claim is lodged correctly and within time. For gradual-onset injuries, I help establish the correct injury date based on the medical evidence.
Common issues
- Gradual-onset injuries (e.g., hearing loss, repetitive strain) have uncertain injury dates — the date of incapacity is often used
- Psychological injury claims in NSW have additional thresholds under section 11A — the injury must not be wholly or predominantly caused by reasonable management action
- The employer's insurer, not the employer, ultimately decides the claim — but the employer must forward it within 7 days
