Overview
How this affects your claim in practice
There is no single NSW workers compensation “payout”. A claim may involve weekly income support, medical and treatment expenses, a section 66 lump sum for permanent impairment, or work injury damages for economic loss where the threshold, negligence and other requirements are met. Each pathway uses different evidence and has different consequences, so an average settlement figure is usually misleading.
- Weekly payments are calculated income support, not a one-off settlement.
- Treatment expenses depend on the accepted injury and whether care is reasonably necessary under the applicable law.
- A physical section 66 claim generally requires permanent impairment greater than 10% WPI.
- A primary psychological section 66 claim requires at least 15% WPI; secondary psychological impairment is excluded.
- Work injury damages has a separate section 151H threshold and also requires employer negligence and economic loss.
- A diagnosis, scan or operation does not automatically establish WPI or a payment amount.
Four different compensation pathways
| Pathway | What it addresses | Core evidence |
|---|---|---|
| Weekly payments | Income support affected by PIAWE, current work capacity, earnings and statutory periods. | Payslips, rosters, tax and concurrent-employment records, certificates, actual hours and work-capacity decisions. |
| Treatment expenses | Reasonably necessary treatment and related expenses for the compensable injury, subject to the applicable rules. | Referral or request, clinical rationale, treatment history, expected function and insurer decision. |
| Section 66 lump sum | Permanent impairment once the condition is sufficiently stable for assessment. | Accepted injury, NSW-compliant WPI report, prior impairment evidence and any binding medical determination. |
| Work injury damages | Past lost earnings and future loss of earning capacity where threshold, negligence and other requirements are met. | WPI, workplace breach and causation evidence, wage history, capacity and vocational material. |
Section 66 permanent-impairment lump sums
For physical injury, permanent impairment must generally be greater than 10% WPI before section 66 compensation is payable. For primary psychological injury, the threshold is at least 15% WPI. Secondary psychological impairment is not assessed for permanent-impairment compensation and cannot be added to physical or primary psychological WPI.
The percentage must be assessed under the NSW permanent-impairment guidelines after maximum medical improvement. The assessment method, conversion and combination rules, prior impairment deduction and accepted injury scope can materially affect the result.
Work injury damages is not another name for section 66
Work injury damages requires the applicable section 151H threshold. From 1 July 2026 that is at least 15% for physical injury and at least 25% for primary psychological injury, with later staged psychological thresholds. The worker must also prove employer negligence, causation and economic loss.
Section 151G limits damages to past economic loss caused by lost earnings and future economic loss caused by impaired earning capacity. It is not a payment for pain and suffering or treatment expenses.
Why similar injuries can produce different outcomes
- Different pre-injury earnings, overtime, concurrent employment and current earnings.
- Different accepted injury descriptions and liability disputes.
- Different sustainable work capacity and return-to-work history.
- Different treatment needs and whether treatment is accepted as reasonably necessary.
- Different NSW WPI findings after maximum medical improvement.
- For damages, different negligence, causation and future earning-loss evidence.
Do not compare claim value by diagnosis alone. A back injury label, surgery or imaging result does not reveal the accepted pathway, WPI or economic loss.
Documents to gather before relying on an estimate
- Insurer acceptance, section 78 notices, work-capacity decisions and treatment refusals.
- Payslips, rosters, overtime, tax, superannuation and concurrent-employment records.
- Certificates of capacity, treating reports, imaging, operation reports and rehabilitation plans.
- The complete WPI assessment and the injuries or body systems it includes.
- A dated claim, treatment, payment and return-to-work chronology.
- For damages, workplace safety records, witnesses and evidence of past and future earning loss.
Before accepting or negotiating a figure
Ask which benefit the figure relates to, which injuries are assumed to be accepted, what evidence and calculation were used, and what rights or future payments may be affected. A weekly-payment arrears calculation is not the same as a section 66 offer or damages settlement.
Review and claim procedures can be time-sensitive. A worker should not postpone responding to a liability, treatment or work-capacity decision while waiting for a broad “payout” estimate.

Frequently asked questions
What is the average workers compensation payout in NSW?
A single average is not a reliable guide because weekly payments, treatment expenses, section 66 compensation and work injury damages are different pathways with different evidence.
What is the physical section 66 threshold?
Permanent impairment must generally be greater than 10% WPI for physical injury.
What is the primary psychological section 66 threshold?
It is at least 15% WPI. Secondary psychological impairment is excluded from permanent-impairment compensation.
Does surgery create an automatic lump sum?
No. WPI is assessed under the applicable NSW method after maximum medical improvement; surgery is one fact in the medical history.
Is work injury damages based only on WPI?
No. The applicable section 151H threshold is one gateway. Negligence, causation, economic loss and procedure must also be established.
What should I ask about an insurer figure?
Ask which benefit it covers, the accepted injuries, calculation, supporting evidence and what future rights or payments may be affected.
Need to identify what an offer or estimate actually covers?
Send the written figure, insurer decisions, wage records, medical reports and WPI material. The benefit type, calculation and unresolved risks can then be checked.
