Police event numbers and reporting an accident for a NSW CTP claim

Your first priority is safety and medical care. Call emergency services where needed. Even if injuries seem minor, some symptoms develop over days.

Why it matters legally: early records often become key evidence about mechanism of injury, symptoms, and whether injury was caused by the accident.

Under clauses 4.11–4.13 of the current SIRA Motor Accident Guidelines, a claimant must report the accident to NSW Police within 28 days unless a police officer attended the accident. Give the insurer the police event number if it is available.

An event number is important, but not an absolute precondition to every claim. If NSW Police do not provide one, the insurer must request other information that may verify the accident, such as scene photographs, witness statements, hospital discharge material, media reports, property-insurance records, CCTV or dashcam footage. If requested material cannot be supplied, the insurer may require a statutory declaration explaining why and stating whether police provided an event number.

Police reporting and CTP claim lodgement are separate steps. The approved Application for Personal Injury Benefits must still be given to the relevant insurer. Keep the event number, report date, attending officers (if any), statements supplied and proof of the separate claim lodgement.

• Vehicle registration details and driver names/contacts
• Photographs of vehicles, damage, skid marks, signage, weather, lighting, and the intersection/road layout
• Witness names and phone numbers (independent witnesses are especially valuable)
• Dashcam/CCTV sources (nearby businesses, buses, traffic cameras where available)

Time limits can apply to obtaining CCTV. If footage exists, act quickly to request preservation.

It is common for people to apologise after a crash. However, early statements can later be treated as admissions. If you are unsure what happened, it is usually safer to describe what you observed rather than speculate.

If contributory negligence is alleged (for example, speed, seatbelt, distraction), the quality of early evidence can be decisive in a dispute.

Special rules may apply if the at-fault vehicle is unidentified (hit-and-run) or uninsured. Early reporting and evidence is often critical in these matters. Get advice as soon as possible.

These matters also commonly create downstream disputes about insurer identity, review rights, and whether urgent steps were taken to preserve evidence. See internal review, PIC merit review vs medical assessment, and unidentified vehicle claims.

• Independent witness evidence: names, numbers, and short contemporaneous summaries of what each witness saw
• Scene mechanics evidence: vehicle position, point of impact, road markings, lighting, weather, debris, and damage patterns
• Police and reporting chronology: when the crash was reported, what event number issued, and whether any later statement corrected an early inaccuracy
• Video preservation steps: proof that you asked for dashcam, CCTV, or business footage before routine deletion
• Early medical causation records: ambulance, hospital, GP, and certificate notes that match the accident mechanism and first symptoms

These records often become decisive if the insurer later alleges contributory negligence, disputes the accident mechanics, or says the injury presentation is inconsistent with the reported crash.

• Waiting too long to identify witnesses or footage: evidence often disappears within days.
• Giving a broad fault admission when the facts are still unclear: speculative language can become insurer shorthand for liability denial later.
• Failing to keep your own copy of reports and correspondence: do not assume police, insurers, or repairers will preserve everything in an accessible form.
• Letting the medical history drift away from the crash account: if symptoms evolve, update your doctor so the chronology remains clear.
• Separating accident reporting from claim strategy: reporting, treatment, insurer identification, and the benefits application all work better when the timeline is consistent from the start.

The best early files are not just a police event number and a few photos. They show a clean chronology from the crash scene into treatment, insurer notification, and any later dispute.

• One dated chronology: crash time, location, police contact, witness follow-up, CCTV requests, first treatment, and when symptoms were first reported.
• Consistent mechanism records: scene photos, vehicle damage, ambulance or hospital notes, and GP records all describing the same crash mechanics.
• Preservation proof: emails, screenshots, or notes showing you asked for dashcam, business CCTV, or witness details before they disappeared.
• Pathway separation: if there are several issues, keep liability, treatment, weekly benefits, threshold, and insurer-identity questions clearly separated rather than mixing everything into one narrative.
• Decision-ready records: keep insurer acknowledgements, claim references, and any early reasons for concern so internal review or PIC escalation can later be mapped document-by-document.

This is especially important where the insurer may later argue contributory negligence, a mostly-at-fault position, inconsistent reporting, or uncertainty about the correct insurer.

Early reporting problems do not stay isolated for long. A weak scene record can later affect liability, weekly payments, treatment approvals, and settlement timing.

• Liability and contributory negligence: if the accident mechanics are vague, the insurer may fill the gaps with its own fault assumptions. See contributory negligence.
• Unidentified or uninsured vehicle issues: if the other vehicle details are incomplete, your proof of prompt police reporting, witness enquiries, and CCTV requests may become critical. See Nominal Defendant claims and unidentified vehicle claims.
• Medical causation arguments: if your first treatment notes do not match the crash account, the insurer may later say the injuries were not caused by the accident or were exaggerated.
• Review and PIC readiness: if the file is not organised early, internal review and Personal Injury Commission disputes become slower and more expensive to prepare.

If the insurer is already relying on scene-history inconsistencies, police summaries, or missing witness evidence, it is sensible to read the internal review and PIC pathway pages early rather than waiting until benefits or liability have already been affected.

After the accident is reported and evidence preserved, the usual next step is medical treatment and lodging the correct benefits application.
