Can You Claim WorkCover for an Old Injury or After Resigning? NSW Rules Explained
The short answer
Yes — in most cases you can still claim WorkCover for an old injury, and yes, you can still claim after you've resigned. NSW workers compensation law protects the injury, not the job title you held at the moment you lodged the paperwork. What matters is when the injury happened, when you became aware it was work-related, and how well you can document it.
This guide walks you through the rules for both situations, the time limits that actually apply (they're longer than most people think), and what to do right now if you suspect you've missed the boat. Most of the time, you haven't.
How long after an injury can you claim WorkCover in NSW?
The general rule in NSW is that you should lodge a workers compensation claim within 6 months of the injury happening. That sounds strict, but the fine print matters enormously — and it's where most workers wrongly rule themselves out.
The 6-month clock can start from one of two dates, whichever is later:
- The date of injury — the day the accident happened, or
- The date you became aware the injury was caused by your work.
That second date is critical. For a broken wrist from a forklift accident, the two dates are the same. But for repetitive strain, hearing loss, chronic back pain, silicosis or a psychological injury, the "date of awareness" can be years after the physical cause began. The clock only starts ticking when a doctor tells you your condition is linked to your work.
Even beyond 6 months, claims can be accepted if the insurer is satisfied the failure to lodge was caused by ignorance, mistake or other reasonable cause. Don't assume you're out of time until a doctor and a lawyer have looked at your specific situation.

Claiming for an old injury — months or years later
Old injuries are one of the most common reasons people call us thinking they've missed the window. Often they haven't. The key is proving two things: that the injury happened (or materially worsened) because of your work, and that your current condition is a continuation of that original problem.
When the clock actually starts
For gradual-onset conditions, the "date of awareness" test changes everything. Common examples:
- RSI and tendon injuries — often creep up over months of repetitive work.
- Back and shoulder pain from years of lifting, driving or standing.
- Industrial deafness — hearing loss can be diagnosed years after exposure.
- Psychological injuries — anxiety, depression or PTSD from workplace stressors.
- Occupational diseases — dust, chemical or asbestos-related conditions.
In all of these, the 6-month clock starts when a medical professional first tells you the condition is work-related — not when the symptoms began.
Medical evidence — the missing piece
A claim for an old injury lives or dies on the medical report. You need a doctor who can examine you now, review your history, and write a clear opinion connecting your current condition to your previous work. Generic GP notes usually aren't enough — insurers scrutinise old-injury claims closely.
This is where our WorkCover doctors help. They're experienced in building the retrospective paper trail insurers actually accept: a certificate of capacity, a causation opinion and the right diagnostic codes. If you've already seen other doctors over the years, that's a good thing — those records become supporting evidence.
Aggravation of a pre-existing injury
A lot of workers assume that because they had a dodgy knee, a bad back or a previous accident before starting the job, they can't claim. That's wrong.
Under NSW law, you can claim if your work materially contributed to aggravating, accelerating or exacerbating a pre-existing condition. The employment doesn't have to be the only cause — it just has to be a significant one. A healed childhood injury that gets re-aggravated by lifting at work is a claimable injury.
The medical opinion needs to specifically address aggravation. If you're in this situation, tell your treating doctor the full history — don't hide the pre-existing condition, because the insurer will find it anyway, and the claim is stronger when it's upfront.
Claiming WorkCover after you've resigned
Resigning does not cancel your right to claim. This is one of the biggest myths we hear. If the injury happened during your employment, your former employer's workers compensation insurer is still on the hook — regardless of whether you quit, were made redundant, or were dismissed.
To lodge a claim after resignation, you generally need:
- Proof the injury occurred during your employment (incident reports, emails, witness statements, medical records from the time).
- To lodge within 6 months of the injury date, or the date you became aware it was work-related.
- A current medical assessment linking your condition to the work cause.
- Your former employer to be notified — you don't have to confront them directly; the insurer handles the notification and correspondence.
If you resigned partly because of the injury — you couldn't cope with the work, or the environment was making it worse — mention that in your medical consultation. It's often relevant to both the claim itself and any secondary psychological injury.
Can a WorkCover claim be reopened in NSW?
Yes. If you had an accepted claim that was closed — either because you returned to work or payments ceased — it can often be reopened if:
- Your accepted injury has worsened and you need further treatment or time off.
- A new related condition has emerged (for example, a knee injury leading to hip problems from altered gait).
- A previously undiagnosed consequence of the injury has been identified.
Reopening a claim is a separate administrative process from lodging a new one, and the insurer will usually ask for updated medical evidence. Our compensation lawyers can advise on the strongest path — reopening, a new claim, or a common law action — depending on the facts.
Common myths that stop people claiming
If you've resigned, you've lost your right to claim.
Many workers believe leaving a job cancels their WorkCover entitlement.
If the injury happened during employment, you can still lodge a claim after you've resigned — provided you're within the 6-month notice period (extendable in certain circumstances). Your former employer's insurer remains responsible.
You only have 3 months to lodge a claim.
People often confuse NSW rules with other states, or with notification deadlines.
The standard period in NSW is 6 months, running from the later of the injury date or the date you became aware the injury was work-related. Extensions beyond 6 months are possible where the delay is due to ignorance, mistake or other reasonable cause.
Pre-existing injuries are never claimable.
Workers assume that because they had a back problem before the job, the insurer will knock them back.
An aggravation or acceleration of a pre-existing condition is claimable if the work materially contributed to it. You don't need to have been perfectly healthy before the job — you just need the work to have made things worse.
What to do right now if you think you're in this situation
If you're reading this because you're worried about time limits, take three simple steps today. Don't sit on it — the clock moves faster than you think.
- 1. Get a medical assessment from a WorkCover-experienced doctor. This is the foundation of everything. Book an appointment with our WorkCover doctors — we handle the paperwork and the insurer pays our team directly, so there's no out-of-pocket cost to you for the certificate of capacity.
- 2. Check you're within the time limit. For gradual-onset or old injuries, the date of awareness is what counts. Our team can help you work out which date applies to your situation and whether an extension might be needed.
- 3. Lodge the claim — don't delay. Even if you think you're borderline out of time, it's better to lodge and let the insurer assess it than to assume you've missed out. If there's a dispute over time limits, our compensation lawyers can advise on extensions and review your case.
For a broader walkthrough of what to do after a workplace injury, see our injured at work guide, or if you're still weighing up whether to claim at all, this piece on whether you should claim covers the most common hesitations.
- You have 6 months to lodge a WorkCover claim in NSW — measured from the injury date or the date you became aware it was work-related (whichever is later).
- For gradual-onset, psychological, hearing or occupational-disease injuries, the "date of awareness" can be years after the physical cause began.
- Resigning does not cancel your right to claim — your former employer's insurer is still responsible for injuries that happened during your employment.
- Aggravation of a pre-existing injury is claimable if work materially contributed to it.
- A closed WorkCover claim can often be reopened if the injury has worsened or a new related condition has emerged.
- Medical evidence is the difference between an accepted and rejected old-injury claim — our doctors can assess your specific case and document the causation properly.
- If you think you might be out of time, lodge anyway — our compensation lawyers can advise on time-limit extensions and dispute resolution.
