How do you claim workers compensation in NSW?
To claim workers compensation in NSW, report the injury to your employer, see your nominated treating doctor, obtain a SIRA Certificate of Capacity, and lodge the claim with the employer or insurer. Then track the insurer response, check any weekly-payment calculation against your wage records, and act quickly if payments, treatment, or liability are delayed or disputed.
This page is a general guide, not a guarantee of entitlement. The evidence usually matters as much as the form itself: incident records, medical notes, certificates, rosters, payslips, witness details, and written insurer decisions all help show what happened and what support is being sought.

NSW workers compensation claim checklist
Use this checklist before the claim becomes a dispute. It keeps the core claim-process intent in one place for workers searching “how to claim workers compensation NSW”.
Medical certificate
Ask your nominated treating doctor to complete a SIRA Certificate of Capacity that records the work-related injury, capacity, treatment, and review plan.
Claim and incident evidence
Keep the claim form, Register of Injuries entry, incident report, photographs, witness names, and all emails or text messages about the injury.
Wage evidence
Collect recent payslips, rosters, overtime, allowances, shift penalties, and second-job income details so weekly payments can be checked.
Insurer decision trail
Save provisional liability notices, reasonable-excuse letters, treatment decisions, work capacity decisions, and any section 78 notice.
If the insurer does not accept the claim
A delay, reasonable excuse, treatment refusal, work capacity decision, or section 78 notice needs a different response. Start with the missing reason, gather targeted medical and factual evidence, and consider the PIC dispute pathway if review or negotiation does not resolve it.
The NSW Claim Journey
Report the injury and record it
Tell your employer as soon as possible after the injury and make sure the incident is recorded in the workplace Register of Injuries. If reporting is delayed, write down why, who you told, and when.
See Your Nominated Treating Doctor (NTD)
Consult your GP and explain clearly that the injury is work-related. They will issue a SIRA Certificate of Capacity. This is the single most important document for starting your weekly payments.
Lodge the workers compensation claim
Your employer should notify the insurer promptly after your report. You can also lodge a claim form directly with the insurer if there is delay or uncertainty. Keep copies of the claim form, certificate, incident record, wage records, and emails.
Provisional Liability Period
The insurer usually has 7 days to start provisional weekly payments and medical expenses (up to $10,000) while they investigate. This is not an admission of full liability but provides immediate financial support.
The Formal Liability Decision
Within a set period (usually 21 days after a formal claim), the insurer must decide to either accept full liability, deny the claim (Section 78 notice), or request more time for medical investigations.

What usually goes wrong before a claim becomes a dispute
The claim-start phase looks administrative, but this is usually where the insurer builds the position it later relies on. If the first certificate is vague, wages are not checked, treatment stalls, or a “reasonable excuse” stretches too long, the problem can shift from a simple claim into a much harder dispute.
Provisional liability delay gets normalised
Workers often assume silence means the insurer is still processing paperwork. Sometimes it does. Sometimes it is the start of a liability fight. Compare the provisional liability guide with the section 78 notice guide if time keeps stretching without a clear answer.
Early wage mistakes become weekly-payment underpayments
If overtime, penalties, or second-job income are missed at the start, the insurer may keep using the wrong figure for months. The PIAWE calculation guide and recalculation pathway help workers spot that before arrears build up.
Treatment delay weakens the whole file
A delayed scan, specialist review, or surgery opinion is not just a medical inconvenience. It can also weaken the later evidence picture used for work capacity, impairment, and causation arguments. See the treatment denial guide and surgery denial guide.
Capacity framing starts before workers realise it
Once the insurer starts focusing on “suitable employment” and current work capacity, the claim is already moving toward a weekly-payments dispute. The work capacity guide explains how that shift affects payments and strategy.
Frequently Encountered Friction
While many claims proceed without issue, most injured workers will encounter one of the following "friction points" where the insurer disputes an entitlement:
- The "Reasonable Excuse": Insurers using minor paperwork gaps to delay provisional payments. See provisional liability rules for what can and cannot be delayed.
- Liability Denial (Section 78): Formally rejecting the claim based on medical or factual disputes. Read how to challenge a section 78 notice.
- PIAWE Calculation Errors: Under-calculating your pre-injury earnings by omitting overtime or bonuses. Use the PIAWE calculation guide to benchmark your entitlement.

Claim Start FAQs
How do I claim workers compensation in NSW?
Start by reporting the injury to your employer, seeing your nominated treating doctor for a SIRA Certificate of Capacity, and lodging the claim with the employer or insurer. Keep evidence of the injury, work connection, wages, treatment needs, and every insurer response.
How long does an insurer have to start provisional payments in NSW?
In many cases, the insurer has 7 days from notification to commence provisional liability payments and treatment support unless a lawful reasonable excuse applies.
What if my claim is denied under section 78?
A section 78 notice can be challenged. You can seek an internal review, obtain stronger medical evidence, and escalate the dispute to the Personal Injury Commission where needed.
Can weekly payments be underpaid because of PIAWE errors?
Yes. Insurers sometimes exclude overtime, allowances, or shift penalties from pre-injury average weekly earnings (PIAWE). Reviewing payroll data early can materially increase weekly payments.
Has your claim been delayed?
If it has been more than 7 days since you reported your injury and you have not received a decision or payment, act quickly before delay turns into a formal dispute.
