A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).
In New South Wales, a claimant must demonstrate a permanent impairment of at least 10% under the whole person impairment (WPI) scale to qualify for certain compensation benefits under the Motor Accident Injuries Act 2017. This threshold determines whether a claimant is eligible for weekly income payments, treatment and care benefits, or damages for loss of earnings. In the Newcastle and Hunter regions, injured persons must provide detailed medical evidence to meet this threshold. This article explains what documentation is required to support a claim and how the 10% impairment threshold is applied by the State Insurance Regulatory Authority (SIRA).
What is the permanent impairment threshold for CTP claims in NSW?
Under NSW law, a claimant must prove a permanent impairment of at least 10% using the WPI scale to access specific benefits. This threshold is defined in Schedule 1 of the Motor Accident Injuries Act 2017 and is applied by SIRA when assessing claims. The 10% threshold is not a fixed injury but a measure of overall impairment that considers all injuries sustained in the accident. For example, a claimant with multiple minor injuries that collectively result in a 10% impairment would qualify, while a single injury below 10% would not.
What documentation is required to prove permanent impairment for CTP claims?
To support a claim for permanent impairment, injured persons must provide comprehensive medical records. Key evidence includes:
- A detailed medical report from a registered medical practitioner confirming the impairment
- Imaging reports (e.g., MRI, X-ray) showing the extent of injuries
- A completed SIRA-formatted impairment assessment
- Evidence of ongoing treatment and recovery progress
- Documentation of how the injury affects daily activities or employment
In Newcastle and Hunter, claimants should seek medical attention promptly and ensure all records are submitted to SIRA. Delayed documentation may weaken a claim, as the 52-week statutory benefit period applies to threshold injuries.
How does SIRA apply the permanent impairment threshold to injury assessments?
SIRA uses the Motor Accident Guidelines to assess impairments. For example, a spinal nerve-root injury producing neurological signs may qualify as a threshold injury, while radiculopathy requires specific clinical signs. In the Hunter region, SIRA clinics and approved medical practitioners apply these guidelines consistently. Claimants should request a copy of the impairment assessment and review it for accuracy. If a claimant believes the assessment is incorrect, they may seek a second opinion from an independent medical practitioner.
Practical steps for claimants in Newcastle and Hunter
- Obtain a comprehensive medical report from a registered medical practitioner
- Submit all injury-related records to SIRA within 52 weeks of the accident
- Request a copy of the impairment assessment to understand how injuries are evaluated
- Seek legal advice if the claim is denied or if there are disputes about the impairment rating
Time limits and when to seek advice
Claimants must submit a claim to SIRA within 52 weeks of the accident if they want to access weekly benefits or treatment and care payments. For claims involving permanent impairment, the 52-week period applies to statutory benefits, but damages claims may extend beyond this timeframe. Injured persons should consult a legal professional if they receive a claim denial or if they are unsure whether their injuries meet the 10% threshold.
