Medical Certificate Requirements for NSW CTP Claims

A valid medical certificate is the "currency" of your CTP claim. Without a specific SIRA-compliant certificate from your GP, the insurer cannot pay your weekly income support or approve many medical treatments. General information only.

1) The SIRA Certificate of Fitness

You must use the official SIRA Certificate of Fitness form. This form is designed specifically for motor accident injuries and asks your doctor to provide details on:

  • Your diagnosis and accident-relatedness.
  • Your capacity for work (total, partial, or full capacity).
  • Any specific work restrictions (e.g., lifting limits, reduced hours).
  • The treatment plan (physio, specialist referrals, etc.).

2) Why the certificate is critical

The insurer relies on this document to determine your "fitness for work." If your doctor says you have "total incapacity," you generally receive your full weekly benefit. If they say you have "partial capacity," the insurer may expect you to return to light duties, and your payments may be adjusted accordingly.

3) Common certificate errors to avoid

  • Incomplete fields: If the GP misses a section (like the diagnosis or capacity dates), the insurer may reject the certificate and delay your payment.
  • Vague restrictions: Restrictions like "light duties" are often too vague. It is better to have specific limits (e.g., "no lifting over 5kg").
  • Gaps in dates: Ensure your next certificate starts the day after the previous one expires to avoid "payment gaps."

4) Your first certificate after the crash

Ideally, see your GP within 48-72 hours of the accident. This ensures your injuries are documented early, which is vital for proving causation later—especially if the insurer tries to argue your injuries are "threshold" or pre-existing.

Frequently asked questions

Can I use a regular medical certificate for my CTP claim?
No. The insurer requires a specific "SIRA Certificate of Fitness". A standard GP sick note is generally not sufficient to process your claim for weekly payments.
Who can complete the CTP medical certificate?
Usually, your regular General Practitioner (GP) completes the certificate. In some cases, a treating specialist can also complete it once the initial claim is established.
How often do I need a new certificate?
To continue receiving weekly income support, you must provide updated certificates regularly—typically every 28 days—unless the insurer agrees to a longer interval.
