Key Takeaway: SIRA, the State Insurance Regulatory Authority, is the NSW Government regulator of CTP Green Slip and workers compensation insurance. It licenses and polices insurers but does not pay your claim: under the Motor Accident Injuries Act 2017, the at-fault vehicle’s CTP insurer does. Lodge your benefits claim within 3 months; NSW motor vehicle accident lawyers can help.

What is SIRA: Quick Answers

What is the purpose of SIRA?
SIRA’s job is to make sure the NSW insurance schemes protect the people who need them and stay affordable. It regulates CTP Green Slip insurance, workers compensation and home building compensation, licenses the insurers, sets the rules they must follow and penalises breaches. For people hurt on the road, it runs CTP Assist on 1300 656 919.
What does SIRA stand for?
SIRA stands for the State Insurance Regulatory Authority. It is a NSW Government agency. It is a regulator, not an insurer: it does not sell policies or pay claims. icare is a separate NSW agency that manages the workers compensation Nominal Insurer and the Lifetime Care and Support scheme.
Is SIRA NSW only?
Yes. SIRA regulates NSW schemes only, including CTP insurance for NSW-registered vehicles. Each state runs its own CTP scheme. In Western Australia, for example, the Insurance Commission of WA is the CTP insurer, and Withstand Lawyers acts for people injured there too: see our guide to ICWA claims.
Is CTP under SIRA?
Yes. NSW CTP (Green Slip) insurance is regulated by SIRA under the Motor Accident Injuries Act 2017. SIRA has licensed 6 insurers to sell Green Slips: AAMI, Allianz, GIO, NRMA, QBE and Youi. Each sets its own price within SIRA’s rules, and you can compare all six on the Green Slip Price Check.
What is a SIRA certificate?
For an injury claim, it usually means the medical certificate on SIRA’s form. A CTP claim needs a certificate of fitness from your GP; a workers compensation claim needs a certificate of capacity. To lodge a CTP claim you also need a police event number, available from the Police Assistance Line on 13 14 44.

If you have been hurt in a crash, SIRA’s name is on the claim form, the insurer’s letters and the help line. It is fair to ask whose side it is on.

SIRA is the referee, not the payer and not your lawyer. The at-fault vehicle’s insurer decides and pays your claim, and the deadlines run either way: miss the 3-month lodgement deadline and you need a full and satisfactory explanation to claim at all.

What does SIRA do in NSW?

SIRA regulates the three NSW statutory insurance schemes: CTP Green Slip insurance, workers compensation and home building compensation. It also has some functions in the Lifetime Care and Support and Dust Diseases schemes. It licenses insurers, sets the rules for how they handle claims, checks they comply and penalises breaches (SIRA).

What SIRA does What it means for you
Licenses CTP and workers compensation insurers Only licensed insurers can sell a NSW Green Slip. There are 6.
Sets claims-handling rules The insurer must contact you within 3 days of your claim and decide liability for treatment and lost income within 4 weeks.
Monitors and penalises insurers SIRA can impose licence conditions and civil penalties. On 27/10/2026 it imposed 8 civil penalties totalling $479,500 on NRMA Insurance for breaching the Motor Accident Injuries Act 2017, the Motor Accident Guidelines and its insurer licence.
Runs CTP Assist Free help on 1300 656 919 with forms, finding the insurer and getting support.
Publishes insurer performance You can compare how CTP insurers perform before you buy a Green Slip.

SIRA does not pay claims, decide disputes or act for you. That split causes most of the confusion: people call SIRA expecting it to fix their claim, and it can only point them to the right door.

What is SIRA CTP insurance?

SIRA CTP is the NSW Compulsory Third Party scheme, better known as the Green Slip. You must buy one to register a vehicle in NSW. It runs under the Motor Accident Injuries Act 2017 and pays benefits to people injured in a NSW crash: drivers, passengers, riders, pedestrians and cyclists (SIRA).

  • •Who pays: the CTP insurer of the vehicle most at fault. Find it with SIRA’s CTP Connect tool or through CTP Assist.
  • •Fund Levy: part of every Green Slip pays for ambulance and initial hospital care, and Lifetime Care for people with severe injuries.
  • •Scale: 14,789 new CTP claims and $1.7 billion in claim payments in 2024-25, an average of $70,106 per claim paid (SIRA Annual Report 2024-25). Our guide to a CTP claim in NSW covers the forms.

Who does what in a SIRA CTP claim?

SIRA explains, the insurer decides, the Independent Review Office hears complaints, and the Personal Injury Commission resolves disputes. Here is who to contact, and when.

What can SIRA’s CTP Assist help with?

CTP Assist is SIRA’s free help line for anyone affected by a NSW motor crash: 1300 656 919, 8:30am to 5pm weekdays. It helps you complete the forms, check eligibility, find the right insurer, and reach legal, community and trauma and grief support (SIRA).

It explains the process; it does not argue your case. SIRA’s CTP Legal Advisory Service funds advice for some disputes, but never for a damages claim. For a lump sum, you need your own lawyer.

How do you make a SIRA CTP claim in NSW?

You make the claim with the at-fault vehicle’s CTP insurer, not with SIRA, in 5 steps:

  1. Get a police event number from the Police Assistance Line on 13 14 44.
  2. See your GP for a certificate of fitness on SIRA’s form. Keep every receipt and your pay slips.
  3. Find the insurer with CTP Connect or CTP Assist.
  4. Lodge your Application for Personal Injury Benefits with the insurer, through your MyServiceNSW account, or by email or registered post.
  5. Hold the insurer to its deadlines: contact within 3 days, a liability decision on treatment and income within 4 weeks, and weekly payments starting within 10 working days.

The benefits claim has two separate clocks: 3 months to lodge, and 28 days for automatic backdating.

When you lodge Can you lodge? Weekly payments backdated to the day after the accident?
Within 28 days Yes Yes, automatically. No explanation needed.
After 28 days, within 3 months Yes, on time. No explanation needed to lodge. Only with a full and satisfactory explanation. Without one, payments start from the date of the claim.
After 3 months Only with a full and satisfactory explanation, and within 3 years (no 3-year limit for a death or impairment more than 10%) No. Payments start from the date of the claim.

For the lump sum, lodge your Application for Common Law Damages within 2 years to keep weekly payments running, and no later than 3 years without a full and satisfactory explanation. More in our guide to how long you have to claim after a car accident.

What can you claim under the SIRA CTP scheme?

Two things: statutory benefits, paid as you go, and a lump sum for more serious injuries. Which you get depends on fault and on whether your injury is a threshold injury (soft tissue injuries and undiagnosed psychological conditions etc) or a non-threshold injury (a break, fracture, nerve damage, or PTSD etc).

  • •Weekly payments: 95% of pre-accident earnings for weeks 1 to 13, then 85% if you are partly working or 80% if you are not, for weeks 14 to 52. The maximum is $5,264 a week from 1 October 2026.
  • •Treatment and care: reasonable and necessary medical, rehabilitation and care costs.
  • •Lump sum: needs a non-threshold injury (a fracture, tear, nerve damage or PTSD etc) and that you were not mostly at fault. Pain and suffering also needs whole person impairment of more than 10%, and is capped at $712,000 from 1 October 2026. See pain and suffering compensation.
Threshold injury Non-threshold injury (a fracture, tear, nerve damage or PTSD etc)
Weekly payments Up to 52 weeks Beyond 52 weeks if not mostly at fault
Treatment and care Up to 52 weeks Can continue beyond 52 weeks
Lump sum No Yes, if not mostly at fault

Being mostly at fault or having only threshold injuries limits benefits to 52 weeks, with no lump sum. See threshold vs non-threshold injuries.

A real NSW result: Brad, 35, was rear-ended. His whiplash, shoulder tear and lumbar disc injury were assessed at 13% whole person impairment, and he received $400,000. Every claim turns on its own facts. See more of our results on our claims won page, or typical ranges in our NSW payouts guide.

Can SIRA help if you disagree with your CTP insurer?

Not directly. SIRA does not overturn insurer decisions. Use the right channel:

  1. Internal review: ask the insurer within 28 days of receiving the decision.
  2. Personal Injury Commission: still unhappy? Apply to the Personal Injury Commission for an independent review.
  3. Independent Review Office: for delays, missing documents or poor claim handling, call 13 94 76. It can investigate and recommend, but cannot change a decision.

Disputes about fault, the threshold label or your impairment decide whether a lump sum is possible. That is where CTP lawyers earn their place.

Does SIRA also regulate workers compensation?

Yes. SIRA regulates NSW workers compensation too; call 13 74 72 for help. Insurers, including the icare-managed Nominal Insurer, pay the claims (SIRA). See our NSW workers compensation lawyers, or what you can claim in our NSW workers compensation payout guide.

Hurt in a crash while working? You may need both claims, and must claim CTP treatment and care within 3 months after workers compensation medical payments stop. See accident while driving for work.

Do you need a lawyer for a SIRA CTP claim?

Not always. If your injuries are minor and heal in weeks, CTP Assist and the insurer may be all you need. Get advice early if:

  • •you have a non-threshold injury (a fracture, tear, nerve damage or PTSD etc), or the insurer labels your injury threshold and it’s not
  • •the insurer says you were mostly at fault (see not at fault car accident claims)
  • •you are off work for more than a few weeks, or thinking about a lump sum

You cannot reopen a lump sum once you settle. Withstand Lawyers works on a no win no fee basis, and our CTP compensation calculator gives a first estimate. Most people deal with SIRA once; the early decisions are the ones that last.

What is SIRA: Frequently Asked Questions

How do I make a CTP claim in NSW?
Get a police event number from 13 14 44, see your GP for a certificate of fitness, find the at-fault vehicle’s insurer with CTP Connect, then lodge your Application for Personal Injury Benefits within 3 months. Lodging within 28 days backdates weekly payments to the day after the accident. Our guide on how to claim CTP walks through each form.
What is the average CTP payout in NSW?
SIRA’s 2024-25 average was $70,106 per claim paid. That average includes many small benefits-only claims. Lump sums for serious injuries are much higher: Brad, 35, received $400,000 for whiplash, a shoulder tear and a lumbar disc injury at 13% whole person impairment. Pain and suffering is capped at $712,000.
What are the current CTP rates for SIRA?
Weekly payments are 95% of pre-accident earnings for weeks 1 to 13, then 85% if partly working or 80% if not, for weeks 14 to 52. The maximum is $5,264 a week from 1 October 2026. Green Slip prices are set by each insurer within SIRA’s rules; compare them on the Green Slip Price Check.
How do I complain about my CTP insurer in NSW?
Raise it with the insurer first. If it is not resolved, complain to the Independent Review Office on 13 94 76, which handles complaints about CTP and workers compensation insurers in NSW. It can investigate delays and claim handling, but not change a decision. Complaints about SIRA itself go to SIRA under its complaint handling policy.
What is the SIRA CTP Assist phone number?
1300 656 919, from 8:30am to 5pm, Monday to Friday, or email ctpassist@sira.nsw.gov.au. For workers compensation, call SIRA on 13 74 72. Need an interpreter? Call TIS National on 13 14 50 and ask for the number you need. Leave a message after hours and CTP Assist will call you back.
Can I make a CTP claim if the accident was my fault?
Yes. Anyone injured in a NSW motor crash can claim statutory benefits, whoever was at fault. If you were mostly at fault, meaning more than 61% responsible, benefits stop at 52 weeks and there is no lump sum. Fault is often disputed, so get advice before you accept the insurer’s finding. See fault in NSW car accident claims.
How long do I have to make a CTP claim in NSW?
Lodge your benefits claim within 3 months. Lodging within 28 days backdates weekly payments to the day after the accident. After 28 days and within 3 months, it is only backdated with a full and satisfactory explanation. Lodge your lump sum claim within 2 years to keep weekly payments running, and within 3 years at the latest.
