If you have been injured in a motor vehicle accident in NSW, you cannot access treatment or income support without one specific document: the SIRA Certificate of Fitness.
Many patients in Bella Vista and Kellyville come to our clinic confused about this form. Is it a sick note? Is it a referral?
As a dedicated injury clinic in the Hills District, we want to clear up the confusion. This guide explains exactly what the CTP medical certificate is, why you need a GP (not a physio) to sign the first one, and how to get it approved quickly so you can focus on recovery.
What is a Medical Certificate for CTP Insurance Claims?
A medical certificate for CTP insurance claims (officially known as the SIRA Certificate of Fitness) is the mandatory legal document required to lodge a claim after a car accident.
Whether you live in Bella Vista, Baulkham Hills, or Castle Hill, you cannot submit your Application for Personal Injury Benefits without this form. It serves two vital purposes:
- Medical Proof: It links your injuries directly to the motor vehicle accident.
- Capacity Assessment: It tells the insurer (like Allianz, QBE, or NRMA) exactly what you can and cannot do at work.
Important Note: The first certificate must be signed by a medical practitioner (GP). You cannot have a physiotherapist or psychologist sign the initial certificate for your claim.
The Medical Examination for CTP Claims: Step-by-Step Guide
Getting your certificate isn’t just about printing a form; it requires a specific medical assessment. Here is the process to ensure your paperwork is accepted the first time.

Step 1: Book a “CTP Initial Consultation”
Do not book a standard 10-minute slot. The paperwork for a CTP claim NSW is detailed.
- Action: When you call WorkCover Hills Doctor (or your local GP), specifically ask for a “CTP Initial Consultation” (20–30 mins).
- Local Tip: If you are in Kellyville or Rouse Hill and finding it hard to get a long appointment with your regular GP, our clinic in Bella Vista prioritizes accident claims to prevent delays.
Step 2: The Physical Assessment
During the medical examination for CTP claims, your doctor must physically examine you to verify your injuries. We will check for:
- Range of Motion: (e.g., how far you can turn your neck).
- Neurological Signs: (e.g., tingling, numbness, or reflex issues).
- Psychological Impact: (e.g., anxiety when driving near the crash site).
Step 3: Documenting the “Mechanism of Injury”
This is the most critical part. You must explain the “mechanism of injury” clearly—meaning exactly how the crash impacted your body.
- Bad Example: “I hurt my neck.”
- Good Example: “I was rear-ended at 60km/h while stationary, causing my head to snap forward and back (whiplash).”
This detail allows us to medically link your pain to the accident, preventing the insurer from arguing it was a “pre-existing” condition.
Understanding “Capacity” vs. “Unfit for Work”
A standard sick note usually just says “Unfit for work.” However, for a CTP insurance claim, the medical evidence must be far more detailed regarding your functional capacity.
Fit for Suitable Duties
Most patients are not “totally unfit” but have specific restrictions. We may certify you as “Fit for suitable duties” with conditions such as:
- Lifting Restrictions: e.g., “No lifting greater than 5kg due to lumbar strain.”
- Postural Tolerances: e.g., “Must alternate sitting and standing every 30 minutes.”
- Travel Limits: e.g., “Cannot drive for work purposes due to medication or neck stiffness.”
Psychological Capacity
If the accident has caused significant stress or PTSD, we can document this on your certificate. For example, if you are a delivery driver but are now too anxious to drive in heavy traffic, we can certify you as unfit for driving duties while remaining fit for administrative duties.
How to Use Your Certificate to Lodge a Claim
Once you leave our clinic with your signed SIRA Certificate of Fitness, you must act quickly.
- Scan the Certificate: Ensure all pages are clear.
- Complete the Claim Form: Fill out the Application for Personal Injury Benefits.
- Attach Documents: You must attach your CTP medical certificate, your Police Event Number, and proof of earnings (payslips).
- Submit: Send the complete package to the CTP insurer (not SIRA directly).
Pro Tip: You generally have 28 days from the date of the accident to lodge this form if you want your wages backdated to the day of the crash.

Frequently Asked Questions (FAQ)
Q: What documents should I attach to CTP claim applications?
A: You must attach your medical certificate for CTP insurance claims (Certificate of Fitness), proof of identity, your Police Event Number, and evidence of your pre-accident earnings (if claiming lost wages).
Q: Can a Physiotherapist sign the first certificate?
A: No. Under NSW SIRA guidelines, a medical practitioner (GP) must sign the first certificate. Your treating physiotherapist can often sign subsequent certificates (after the first month).
Q: How long is the medical certificate valid for?
A: A CTP medical certificate is typically valid for 28 days. You must see your doctor for a review before it expires to ensure your weekly payments do not stop.
Q: Do I need to pay for the consultation?
A: If you have an active claim number or an accident notification number, we bill the insurer directly. If you have not yet lodged the claim, you may need to pay upfront, but the insurer will fully reimburse you once they accept the claim.
