Psychiatric Injury Threshold in NSW CTP Claims
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 psychiatric injury may qualify for compensation under the Compulsory Third Party (CTP) insurance scheme if it meets the legal threshold for a 'serious injury'. This threshold applies equally across Greater Sydney and the rest of NSW. To be eligible for damages, a psychiatric injury must be more than minor and must meet the criteria set out in the Motor Accident Injuries Act 2017 (MAIA). The injury must result in a permanent impairment of at least 10% of the whole person, or it must be a threshold injury that causes significant and lasting impact on daily life, including work, relationships, and mental health.
A psychiatric injury is considered a threshold injury if it is caused by a motor vehicle accident and results in a clinically diagnosed condition such as post-traumatic stress disorder (PTSD), major depressive disorder, or an anxiety disorder that significantly impairs functioning. The injury must be supported by medical evidence, including a report from a qualified mental health professional. The Motor Accident Guidelines specify that a diagnosis must be made in accordance with standard clinical criteria, and that the injury must not be attributable to pre-existing mental health conditions unless they were significantly aggravated by the accident.
Time Limits for CTP Claims in NSW
There is a strict time limit for making a CTP claim for a psychiatric injury in NSW. The claim must be made within three years of the date of the motor accident. This three-year period is set out in the Motor Accident Injuries Act 2017 and applies uniformly across Greater Sydney and the rest of the state. The clock starts on the date the accident occurred, not the date of diagnosis or treatment.
If the injury is not diagnosed until after the accident, the three-year limit still begins on the accident date. Delay in seeking medical assessment does not extend the deadline. However, if the injury was not reasonably apparent at the time, and the claimant only became aware of the injury within the three-year window, the claim may still be valid if it is made within three years of the date the injury was first discovered.
Practical Steps and Evidence That Matter
To support a CTP claim for a psychiatric injury, it is essential to act promptly. The first step is to seek medical assessment from a mental health professional, such as a psychiatrist or clinical psychologist, as soon as symptoms arise. A formal diagnosis is required to establish the injury and its connection to the accident.
Key evidence includes:
- A medical report detailing the diagnosis, symptoms, and functional impairment
- A history of treatment, including therapy sessions, medication, and hospital visits
- A statement from a treating practitioner confirming the injury is a result of the motor accident
- Evidence of impact on daily life, such as absence from work, inability to perform household tasks, or withdrawal from social activities
- Photographs of the accident scene, if available
- Witness statements, if any were present at the time of the accident
Preserving records of communication with insurers, including written correspondence and email exchanges, is also important. Failure to notify the insurer within a reasonable time may affect the claim, although the statutory three-year limit remains the primary deadline.
How the Threshold Applies in Greater Sydney
The psychiatric injury threshold and time limits apply consistently across Greater Sydney. There is no variation in the legal test based on location within the region. Whether the accident occurred in the Sydney CBD, North Shore, or Western Sydney, the same criteria under the MAIA and Motor Accident Guidelines apply.
However, the nature of the accident and the context may affect whether the injury is accepted as arising from the motor vehicle incident. For example, a claim for PTSD following a high-speed collision on a major road in Sydney may be more readily supported than a claim arising from a minor fender-bender in a residential area, depending on the evidence of trauma and medical assessment.
When to Seek Legal Advice
A claim for a psychiatric injury under CTP may be complex, particularly if the injury is not immediately apparent or if the insurer disputes the connection to the accident. The threshold for damages is high, and the burden of proof lies with the claimant to demonstrate that the injury meets the legal definition and that it was caused by the motor accident.
If the claim is denied, or if the insurer offers a settlement that does not reflect the full impact of the injury, a review or dispute may be necessary. In such cases, it is advisable to seek independent legal advice before accepting any offer or signing a release.
Hypothetical Example
A 34-year-old office worker in Sydney was involved in a rear-end collision on the M4 motorway in August 2024. The accident caused no physical injury, but the driver experienced severe anxiety, panic attacks, and sleep disturbances in the weeks following. After six months, a psychologist diagnosed PTSD linked to the accident. The claim was made in November 2026, within the three-year limit. The claim was supported by medical reports, therapy records, and a statement from the treating psychologist confirming the injury was caused by the accident. The claim was accepted and compensation was awarded for treatment and care benefits, as well as damages for permanent impairment.
