What is a Section 66 Lump Sum Payment?
A Section 66 lump sum payment is a one-off, tax-free compensation payment available to workers in New South Wales who suffer a permanent impairment resulting from a work-related injury or disease. This lump sum recognises lasting loss or disability after medical treatment has stabilised your condition.
Section 66 payments are in addition to weekly payments and medical expenses under the NSW workers compensation scheme. For official guidance, see the NSW State Insurance Regulatory Authority (SIRA): SIRA – Guide to Workers Compensation.
Who Is Eligible for a Section 66 Payment?
To be eligible you must have:
- Suffered a work-related injury or disease in NSW;
- Reached maximum medical improvement (MMI), meaning your condition is stable; and
- Been assessed as having a qualifying level of Whole Person Impairment (WPI) under SIRA’s Permanent Impairment Guidelines.
The minimum WPI thresholds are:
- Physical injury: at least 11% WPI
- Primary psychological injury: at least 15% WPI
Assessments are performed by SIRA-approved medical specialists using the AMA Guides and the SIRA Permanent Impairment Guidelines. The assessed WPI determines whether you qualify and the value of your lump sum.

How Permanent Impairment Is Assessed
An approved independent medical assessor examines your medical records, treatment history and performs a clinical assessment. The assessor applies the SIRA Guidelines (and relevant AMA criteria) to determine a Whole Person Impairment percentage.
Common factors considered by assessors include:
- Objective diagnostic imaging (MRI, X-ray);
- Clinical findings (range of motion, strength, neurological signs);
- Functional limitations (capacity for work and daily tasks); and
- Response to treatment and rehabilitation progress.
How Much Can You Receive?
The lump sum value depends on the WPI and the statutory benefit table in force at the time of injury. SIRA updates indexes and payment scales periodically — always check the latest SIRA tables: SIRA – Permanent Impairment Benefits.
As a guide (indexation and rates vary):
- ~11% WPI — low five-figure range
- ~15–20% WPI — mid five-figure range
- ~30–40% WPI and above — high five-figure to six-figure ranges
Multiple injuries from the same event can be combined to increase your overall WPI and therefore the lump sum value. PK Simpson will ensure impairments are correctly combined and argued to achieve the best outcome.

Physical vs Psychological Injuries
Section 66 covers both physical and psychological injuries, although thresholds differ. Psychological injuries — such as post-traumatic stress disorder, depression or anxiety attributable to workplace incidents or bullying — require robust medical evidence and typically a 15% WPI threshold.
These claims can be complex; expert medico-legal evidence and early legal advice significantly improve the likelihood of a successful assessment.
Most Common Work Injuries and High-Risk Industries in NSW
PK Simpson frequently handles Section 66 claims arising from the following injury types:
- Manual handling and heavy lifting injuries — lumbar spine and disc injuries;
- Repetitive strain injuries (RSI) — wrist, elbow, shoulder and neck conditions;
- Slip, trip and fall injuries — fractures and soft tissue damage;
- Machinery and crush injuries — amputation, fractures and severe soft tissue damage;
- Vehicle and transport accidents — whiplash, spinal injuries;
- Occupational disease — hearing loss, respiratory conditions;
- Psychological injuries — arising from trauma, bullying or chronic work stress.
Industries with higher injury rates in NSW include warehousing and logistics (Amazon, Adecco, transport operators), construction and trades, manufacturing, healthcare and aged care, and retail. If you work in these sectors and have persistent limitations despite treatment, a Section 66 claim may be appropriate.
The Section 66 Claim Process — Step by Step
- Initial review: Free case assessment with PK Simpson to confirm eligibility;
- Collect evidence: GP notes, specialist letters, imaging and treatment history;
- Arrange IME: Independent medical examination by a SIRA-approved assessor;
- Lodgement: PK Simpson prepares and lodges the Section 66 claim with the insurer;
- Negotiation or PIC hearing: We negotiate with the insurer and, if disputed, represent you at the Personal Injury Commission;
- Settlement: Once agreed or determined, the lump sum is paid and other entitlements continue as applicable.
Important Legal Points
- You can make a Section 66 claim once your condition is stable (MMI).
- If impairment increases after a prior assessment, you may be eligible to apply for a further claim in certain circumstances.
- Section 66 is separate from a common law Work Injury Damages claim — the latter requires employer negligence and typically a minimum 15% WPI threshold.
- All impairment assessments must follow the SIRA Permanent Impairment Guidelines.

Frequently Asked Questions
Yes. Section 66 compensates for permanent impairment (loss of a body function), while Section 67 compensates for pain and suffering. Section 67 requires a higher WPI threshold (at least 10% for most injuries) and is a separate, additional entitlement. A successful Section 66 claim does not preclude a Section 67 claim if you meet those separate criteria.
You are not legally required to use a lawyer, but specialist legal advice significantly improves outcomes. PK Simpson ensures your impairments are correctly documented and combined, your claim is lodged correctly, and your interests are represented in any insurer dispute or Personal Injury Commission hearing. PK Simpson offers a no win, no fee arrangement on most workers compensation matters.
The 15% WPI threshold applies to primary psychological injuries. A SIRA-approved psychiatrist assesses your condition using the Psychiatric Impairment Rating Scale (PIRS) and the SIRA Guidelines. Physical injuries have a lower threshold of 11% WPI. Multiple impairments from the same incident can be combined using a statutory formula to reach the qualifying threshold.
You can apply once your condition has stabilised (reached maximum medical improvement). There is no strict time limit for lodging a Section 66 claim, but there are practical reasons to act promptly — medical records are clearer, witnesses are available, and you receive your entitlement sooner. Claims for injuries before 1 January 2002 may have different rules. Seek legal advice specific to your injury date.
Payment amounts depend on your WPI percentage and the benefit table in force at the time of injury. As a general guide: 11% WPI is typically in the low five-figure range; 15-20% WPI is in the mid five-figure range; 30-40%+ WPI can reach high five-figures to six-figures. SIRA indexes these amounts periodically. PK Simpson can provide a personalised estimate after reviewing your medical evidence.
Any body part or system permanently impaired by a work injury can qualify, including: spine (lumbar, cervical, thoracic), shoulder, knee, hip, elbow, wrist, hand and fingers, foot and ankle, hearing loss, vision loss, and psychological conditions. The WPI is calculated for each impaired body part and combined using SIRA’s formula.
Permanent impairment means your work injury has stabilised (reached maximum medical improvement) and left you with a lasting functional loss. It is assessed as a Whole Person Impairment (WPI) percentage under the SIRA Permanent Impairment Guidelines. Once stable, a SIRA-approved medical assessor examines you and assigns a WPI percentage based on your loss of function.
You can dispute an assessment. If the insurer disputes or you disagree with the WPI finding, the matter can be referred to the Medical Assessment Service (MAS) through the Personal Injury Commission. A Medical Assessor will conduct an independent assessment and issue a certificate that is binding. PK Simpson can advise whether a dispute or further assessment is worthwhile.
