What Evidence Should I Collect After a Car Accident in NSW?
In the minutes after a car accident, most people are shaken, sore and just trying to make sense of what happened. Collecting evidence is the last thing on your mind, and understandably so. Yet what you gather in those first minutes and days can shape any claim you later make, for your injuries or for your car, far more than most people realise. Fault, the seriousness of your injuries, and the losses you can recover all come down to evidence, and evidence fades fast.
The good news is that you do not need to be a professional to do this well. A phone camera, a few details written down, and knowing what matters will put you in a strong position, whether or not you end up needing to make a claim at all.
This guide explains why the evidence matters, what to collect at the scene, how to report the accident, and what to keep in the days that follow. Please treat it as general information rather than advice about your own situation, and you should seek advice about your particular circumstances before making decisions.
Why the evidence you collect after a car accident matters
It helps to understand what the evidence is actually for, because that tells you what is worth gathering.
Most disputes after an accident come down to one of three things. Who was at fault, which decides whether you can recover from the other driver and whether you might be blamed. How serious your injuries are, which affects your entitlements under the CTP scheme. And what you have actually lost, which determines what you can be paid. Each of these is proved, or lost, on evidence.
There is another reason to be thorough. A single accident can give rise to two separate claims, a personal injury claim through the CTP scheme and a property damage claim for your car, and the same evidence often supports both. Gathering it once, properly, protects you on every front.
The table below shows how different kinds of evidence do different jobs.
| Evidence | What it helps establish |
|---|---|
| Photos of the scene, vehicles and damage | How the accident happened and who was at fault |
| The other driver and vehicle details | Who to claim against, and which insurer |
| Witness contact details | Independent support for your version of events |
| Camera footage, such as dashcam or CCTV | An objective record of what happened |
| Medical records and a Certificate of Fitness | The nature and extent of your injuries |
| Payslips and income records | Your loss of earnings |
| Receipts for towing, hire, repairs and treatment | The expenses you can recover |
What to collect at the scene
If it is safe to do so, and once anyone injured has been attended to, the scene is where the most valuable evidence is gathered, because much of it disappears the moment vehicles are moved and people leave.
- Look after safety and health first. Check for injuries, call emergency services if anyone is hurt or there is danger, and move to a safe place if needed. Nothing below matters more than this.
- Get the other driver’s details, including their name, address, phone number, licence details, and the registration, make, model and colour of their vehicle. If they have their insurance details, note those too.
- Take photographs, and take more than you think you need. Capture the position of the vehicles before they are moved if it is safe, the damage to every vehicle, the road and any skid marks, traffic signals and signs, the weather and lighting, and the wider scene.
- Get witness details. The name and phone number of any independent witness is extremely valuable, because an impartial account can settle a fault dispute. People leave quickly, so ask before they go.
- Note the essentials while they are fresh, including the date, time, exact location, the direction each vehicle was travelling, and what happened in your own words.
- Look for cameras. Note any nearby businesses or homes with security cameras, any traffic cameras, and whether any vehicle had a dashcam, including your own.
One thing not to do at the scene is admit fault or apologise in a way that sounds like accepting blame. It is natural to want to smooth things over, but fault is a legal question to be worked out on the evidence, and an offhand admission can be used against you later. Stick to exchanging details and recording facts.
Reporting the accident to police
Reporting matters both practically and for your claim. You are generally required to report a motor accident to police within 28 days, and you will be given an event number, which the CTP insurer will ask for when you claim.
Call triple zero, 000, at the scene if anyone is injured or killed, if a driver has failed to stop and exchange details, if a driver appears affected by alcohol or drugs, or if the accident is causing a hazard or obstruction. In less urgent cases, you can report through the Police Assistance Line on 131 444. Either way, make a note of the event number and keep it somewhere safe.
Medical evidence, even if you feel alright
This is the piece people most often get wrong, and it can quietly undermine an otherwise strong claim.
See a doctor as soon as possible after the accident, even if you think you are uninjured. Injuries such as whiplash, soft tissue injuries and concussion often do not show their full effect for a day or two, and psychological effects can take longer still. A prompt medical record does two things. It makes sure you get the care you need, and it creates evidence linking your injuries to the accident, at a time when no one can suggest they arose from something else.
Ask your doctor to record every symptom, not just the most obvious one, and request a Certificate of Fitness, which is the document a CTP income support claim depends on. As your recovery continues, keep attending your treating practitioners, because the ongoing record of your injuries and their effect on you is some of the most important evidence in a personal injury claim.
Records to keep in the days and weeks afterwards
Beyond the scene and the doctor, a claim is built on the paper trail you keep afterwards. It is far easier to gather this as you go than to reconstruct it later.
Keep every receipt and document connected to the accident, including medical and pharmacy costs, travel to appointments, towing and storage, any hire car, and repair quotes and invoices. If you are losing income because you cannot work, keep proof of your earnings, such as payslips or, if you are self employed, your financial records. It also helps to keep a simple diary of how your injuries are affecting your daily life, your work, your sleep and the things you can no longer do, because that everyday impact is easy to forget months later and is exactly what a claim needs to capture.
Finally, preserve physical evidence where you can. Photograph your damaged vehicle and any damaged property, such as a helmet, phone or child seat, before anything is repaired or thrown away.
How Stephen Young Lawyers can help
Good evidence makes a claim, and gaps in it are the single most common reason claims are undervalued or disputed. The difficulty is that the moment to gather much of it, at the scene and in the first days, is exactly when you are least able to think about claims. That is why getting advice early helps, so that nothing important is lost while it can still be found.
An experienced personal injury lawyer can tell you what evidence your claim needs, help obtain material such as camera footage and records while it still exists, and make sure your injuries are properly documented from the start. Where you were injured, we act on your personal injury claim through the CTP scheme, and where another driver was at fault and had insurance in place, we can also pursue your property damage claim against that driver and their insurer.

No lawyer can promise you a particular outcome, and every claim turns on its own facts. What can be said is that the evidence you gather early is often what a claim later stands or falls on, and that a little care at the start goes a long way.
