Serious Injury Threshold in NSW CTP Claims: Key Changes After 2017 Reforms for Rural and Remote Areas

The 2017 NSW CTP reforms redefined 'serious injury' to focus on clinical criteria, impacting rural and remote claimants. Rural claimants must provide evidence of neurological signs or impairment to qualify for benefits, with strict time limits for claims.

Current as at 25 August 2026

What is the legal definition of 'serious injury' under NSW CTP laws?

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

Under the Motor Accident Injuries Act 2017, a 'serious injury' is defined as an injury that results in a whole person impairment of 10% or more, or a neurological injury meeting specific clinical criteria. This definition replaced the previous medical opinion-based threshold, requiring a more structured assessment of injuries.

How did the 2017 CTP reforms change the assessment of serious injuries?

The 2017 reforms introduced a two-tiered system for assessing injuries. Threshold injuries, those meeting the 10% impairment or neurological criteria, are treated differently from serious injuries. For rural and remote claimants, the reforms clarified that access to specialist medical services does not automatically disqualify a claim, but injuries must still meet the clinical criteria outlined in SIRA's Motor Accident Guidelines.

What are the implications for rural and remote NSW claimants?

Claimants in rural and remote areas may face challenges in accessing specialist medical assessments, which are critical for determining whether an injury meets the 'serious injury' threshold. SIRA's guidelines now explicitly state that injuries must be evaluated based on clinical evidence, not location. This means rural claimants must ensure their medical records clearly document neurological signs or impairment levels.

What evidence is needed to support a serious injury claim?

Key evidence includes: medical reports detailing neurological signs (e.g., radiculopathy), impairment assessments from accredited practitioners, and records of treatment costs. For rural claimants, evidence of access barriers to specialist care may also be relevant to demonstrate that injuries were not misdiagnosed due to limited resources.

Time limits and when to seek advice

Claimants must notify their insurer within 52 weeks of the accident. If injuries are not threshold injuries, benefits are generally limited to 52 weeks. Rural claimants should seek legal advice promptly to ensure medical records are properly documented and claims are submitted before deadlines.

Example: How does the threshold apply in practice?

A rural cyclist injured in a collision may present with back pain and numbness. Under the new rules, the claimant must provide evidence of neurological signs (e.g., radiculopathy) or a 10% whole person impairment. If the injury meets these criteria, it qualifies as a serious injury, entitling the claimant to ongoing benefits.
