Serious Injury Threshold and Caregiver Support in NSW CTP Claims

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).

If you or a family member has suffered a serious injury in a motor accident in NSW, you may be eligible for additional support beyond standard treatment benefits. The serious injury threshold determines whether your claim qualifies for caregiver assistance, long-term care funding, and other benefits under the NSW Compulsory Third Party (CTP) scheme.

Under the Motor Accident Injuries Act 2017, a 'serious injury' is defined as an injury that results in a whole person impairment (WPI) of 10% or more, or a specific injury like a spinal nerve-root injury with neurological signs. This threshold distinguishes claims that require additional support for families, such as funding for caregiving, home modifications, or rehabilitation.

How the Threshold Affects Caregiver Claims

To qualify for caregiver support, your injury must meet the serious injury threshold. This means:

  • You must have a documented impairment of 10% or more.
  • Your injury must involve specific conditions like spinal cord damage, brain injury, or limb loss.
  • Medical evidence must show your injury meets the
  • Motor Accident Guidelines* criteria.

Families often face challenges securing funding for caregiving costs. Under the CTP scheme, you may claim for:

  • Wages lost due to caregiving.
  • Additional living expenses.
  • Rehabilitation services.

Practical Steps for Families

To support your claim, gather:

  • Medical records confirming your injury meets the threshold.
  • Evidence of caregiving needs (e.g., doctor’s notes, care plans).
  • Financial records showing caregiving costs.
  • Witness statements or accident reports.

It’s crucial to notify your insurer promptly and seek medical attention immediately. Delays can affect your ability to claim additional support.

Time Limits and Dispute Resolution

CTP claims must be made within 52 weeks of the accident if your injury is below the serious injury threshold. For serious injuries, the time limit is five years from the accident date. If your claim is disputed, you may need to:

  • Request a review from the insurer.
  • Seek mediation through the NSW Civil and Administrative Tribunal (NCAT).
  • Consult a legal professional to challenge the decision.

When to Seek Legal Advice

Families should consider legal assistance if:

  • The insurer denies your claim.
  • You’re unsure if your injury meets the threshold.
  • You need help navigating complex medical or financial evidence.

Legal professionals can help ensure your claim includes all eligible support, including caregiver costs and long-term care funding.
