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).

Highway merge accidents often lead to disputes over compensation under NSW CTP laws. If you’ve been injured in such an incident, understanding your dispute resolution options is critical. This article explains how to challenge a decision, what evidence matters, and how SIRA’s guidelines apply to claims in the Illawarra and South Coast regions.

NSW CTP Rules Behind Disputes

Under the Motor Accident Injuries Act 2017, CTP claims are governed by statutory benefits and SIRA’s guidelines. For highway merge accidents, disputes typically arise over whether injuries meet the 'threshold injury' definition or if benefits are limited after 52 weeks. SIRA’s resources clarify that claims must be based on medical evidence, not fault, and that disputes must be resolved through internal review or legal action.

Practical Steps for Claimants

To challenge a CTP decision, claimants must first gather evidence: medical records confirming injuries, accident reports, witness statements, and proof of income. In rural areas like the Illawarra, access to legal advice may be limited, so claimants should act quickly. SIRA’s guidelines stress that disputes must be submitted within 52 weeks of the accident, unless a medical review extends this period.

Time Limits and Dispute Options

CTP claims have strict deadlines. Most benefits stop after 52 weeks unless a medical report shows ongoing injuries. If a claimant disputes a decision, they can request an internal review with SIRA or seek mediation through the NSW Civil and Administrative Tribunal (NCAT). Legal action is an option but requires a solicitor and is less common due to costs and complexity.

Example: Disputing a Benefit Cut-off

Consider a claimant injured in a highway merge accident who receives weekly benefits for 52 weeks. If SIRA cuts benefits, the claimant can dispute this by providing a medical report showing ongoing recovery. SIRA’s guidelines state that such disputes must be resolved through internal review before legal action.

When to Seek Advice

Disputes over CTP claims can be complex, especially in rural areas. Claimants should consult a solicitor if they face a benefit cut-off, medical disputes, or delays. SIRA’s resources are a starting point, but independent legal advice ensures all options are explored.
