How SIRA Determines Lump Sum Settlements in Illawarra and South Coast

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).

If you've received a lump sum settlement offer for a NSW Compulsory Third Party (CTP) claim, understanding how SIRA evaluates these offers is critical. SIRA, the NSW government body managing CTP claims, applies specific rules to determine whether a lump sum settlement is appropriate. This article explains how SIRA assesses lump sums in the Illawarra and South Coast regions, what the settlement typically includes, and when it might be wise to accept such an offer.

Key CTP Rules Behind Lump Sum Settlements

Under the Motor Accident Injuries Act 2017 (MAIA), SIRA has discretion to offer lump sum settlements instead of ongoing weekly payments or other benefits. A lump sum is typically available if:

  • The injury is a
  • threshold injury* (as defined in the Motor Accident Guidelines),
  • The claimant’s injuries are unlikely to worsen, and
  • The claimant’s recovery is expected to be complete within a reasonable timeframe.

SIRA evaluates whether a lump sum is appropriate by considering:

  • The nature and severity of the injury,
  • Medical evidence confirming recovery,
  • The claimant’s ability to return to work or normal activities,
  • The financial impact of the injury.

In Illawarra and South Coast, SIRA applies the same legal standards as other NSW regions but may have local administrative practices influencing settlement timing.

Practical Steps and Evidence That Matter

To assess whether a lump sum offer is fair, you should:

  1. Review medical records to confirm that the injury meets SIRA’s threshold criteria. SIRA requires evidence of recovery, such as a medical report stating the injury is resolved.
  1. Compare settlement offers with the MAIA’s statutory benefits. For example, a lump sum may replace weekly payments for a threshold injury, but the total amount must reflect the injury’s impact.
  1. Consider the financial implications. A lump sum may be less valuable than ongoing payments if your recovery is uncertain. SIRA’s offer must be compared to the maximum lump sum available under the MAIA.
  1. Check for SIRA’s specific conditions. In some cases, SIRA may require a preliminary assessment before offering a lump sum, particularly for complex injuries.

Time Limits, Disputes and When to Seek Advice

SIRA must issue a decision on your claim within 52 weeks of the accident (or 104 weeks for serious injuries). If you disagree with the lump sum offer, you can:

  • Request a review through SIRA’s internal process,
  • Appeal to the NSW Civil and Administrative Tribunal (NCAT), or
  • Seek independent legal advice to assess whether to accept or reject the offer.

In Illawarra and South Coast, claimants should be aware that SIRA’s local office may have different administrative timelines. If you’re unsure whether to accept a lump sum, consult a legal professional to evaluate the offer against your long-term needs.

When to Seek Legal Advice

Lump sum settlements are final and cannot be reopened. Before accepting an offer, ensure you:

  • Understand what the lump sum includes (e.g., medical expenses, lost income, pain and suffering),
  • Confirm that SIRA has fully assessed your claim,
  • Consider whether ongoing benefits might be more beneficial.

If you’re in the Illawarra or South Coast regions, contact a legal professional to review your settlement offer and ensure it aligns with your circumstances.
