A rear-end crash in traffic, a collision at an intersection, a lane change that went wrong: around Avon, as anywhere in NSW, the injury claim usually goes to the insurer of the vehicle at fault. When that is obvious, many people never need a lawyer. When the drivers disagree or the insurer says you contributed, advice is often worth having. Our free check helps you tell which situation you're in.

Fault and your claim: four situations
People often assume that being at fault means getting nothing. That isn't how the NSW scheme generally works. The four situations below show what usually changes as your share of the blame goes up.
Situation 1
You were not at fault
No share of the fault is the strongest position. Benefits come from the at-fault vehicle's insurer, and a lump sum damages claim may follow if your injury isn't a threshold injury. The insurer still needs evidence before it accepts fault.
Situation 2
You were partly at fault
Sharing some of the blame generally doesn't stop a claim. It can reduce weekly payments after the first 52 weeks and cut down any damages in proportion. How much is often argued, which is where advice helps.
Situation 3
You were wholly or mostly at fault
'Mostly at fault' means contributory negligence greater than 61%. Weekly payments and treatment and care are then generally limited to the first 52 weeks, with no common law damages. Children 16 and under keep treatment and care for as long as they need it.
Situation 4
No one was clearly at fault
When a crash was nobody's fault, the claim isn't necessarily over. Under the 'blameless accident' rules, an injured person may be able to claim as if someone were at fault. Whether they apply depends on the facts.
General information, not legal advice. Fault and contributory negligence are decided on the evidence. Time limits apply.
Avon roads and the question of fault
On Appin Road, Picton Road or Remembrance Driveway, a crash on a quieter stretch may leave you as the only witness. Your photos and a prompt police report may be the main record of how it happened. Fault is decided on the evidence as a whole. Skid marks, damage patterns and the final positions of the cars can say more than either driver's account. Hospitals serving the area include Campbelltown Hospital. Wherever you were first seen, describe the crash accurately and consistently. Insurers compare early medical notes with later accounts when they decide who caused a collision.
Around Airport & South Line (Glenfield, Ingleburn, Minto, Campbelltown, Macarthur), traffic slows for pick-ups, bus stops and people crossing. A low-speed collision in that setting can still raise real questions about who should have given way, so note what each vehicle was doing.

Fault after a crash: when to call a lawyer, and when you may not need one
Plenty of car accident claims never involve a fault argument. The ones that do often benefit from advice, because fault controls the lump sum. These lists show when a lawyer is commonly worth a call on fault, and when you may manage alone.
Often worth talking to a lawyer
- A fault decision has been made and the review deadline is running
- The insurer puts your share of fault above 61%
- The other driver changed their story after the crash
- Your injury may be more than a threshold injury and fault will decide damages
You may not need one
- You mainly need a doctor to record your injuries
- You only need help identifying the at-fault vehicle's insurer
- You were a passenger and nobody disputes which driver caused it
If what you need now is treatment, start there. Ask us about doctors and allied health, such as GPs, physiotherapists and psychologists, who understand CTP claims and the Certificate of Fitness.

At the scene: what to notice for fault
The insurer that decides fault will not have been there. It relies on what people recorded at the time. So record what you can: the time, the weather, the road surface, the lane markings and the direction each vehicle was travelling. If a witness stopped, ask whether they'll give their name. A note written that evening is worth more than a memory months later.
- Names and phone numbers of anyone who saw it
- Exactly what the other driver said, written down that day
- Whether you and your passengers wore seatbelts
- Weather, light and the road surface at the time

If you were the passenger
A passenger isn't driving, so a passenger is rarely found at fault for the crash itself. The claim goes to the CTP insurer of whichever vehicle was at fault. If your own driver caused it, that's the Green Slip of the car you were in, even when the driver is a friend or family member. The insurer responds to the claim, not the driver personally.
Passengers in a crash between two cars sometimes find that each driver blames the other and neither insurer will accept the claim at first. You don't have to take sides. Give an honest account of what you saw, lodge on time, and let the fault question be worked out between the insurers. If it stalls, that's when advice helps most.

Evidence that settles fault
Fault is decided on evidence, not on who sounds more certain. The usual pieces are the police event number and any police record, photos of where the cars stopped, the damage to each vehicle, dashcam footage and independent witnesses. No single piece is always decisive. Together they usually show what happened, even when the drivers tell different stories.
The police event number links your claim to the official record of the crash. The insurer can use it to check who was involved and what was reported. It's worth getting even if the crash seemed minor and police didn't attend, because a record made close to the time is harder to dispute than one pieced together later.
- Photos of both vehicles' damage and final positions
- Independent witnesses' names and numbers
- Camera footage from nearby shops or homes
- Photos of signals, signs and lane markings
Save footage early
Shops, buses and homes with cameras often keep footage only briefly. Ask in writing as soon as you can, giving the date, time and exact spot.
Seatbelts, speed and your share of fault
A seatbelt argument is the classic example. If the insurer says your injuries were worse because you weren't belted in, it may reduce what you receive. The percentage isn't set by a formula. It's argued on the evidence, including medical opinion about how each injury happened, which makes it worth checking rather than simply accepting.
Check the percentage
If the insurer puts your share of fault above 61%, damages are off the table and benefits are generally limited to 52 weeks. Most insurer decisions can be internally reviewed, generally within 28 days of receiving the decision.

What fault changes in your claim
Most people hurt in a car crash can claim statutory benefits regardless of fault, covering weekly payments and reasonable and necessary treatment. Fault matters most for the lump sum. Common law damages are only possible if another driver was at fault, you were not mostly at fault, and your injury is more than a threshold injury. So a fault finding against you can close off damages even while benefits are paid.
Rules change
The fault rules and benefit limits described here apply to accidents from 1 April 2023. Earlier accidents can have different limits, so check the rules for your accident date.

Chain crashes and split blame
Chain collisions are where fault gets complicated. The driver who started it may carry most of the blame, but a driver behind who was following too closely can share it. Each vehicle has its own Green Slip insurer. Your task is to record every vehicle involved and the order of the impacts; the insurers' task is to sort out which of them responds.
If you were hit from behind and pushed into the car in front, you may have been blameless in both impacts. Make that clear in your account: which impact came first, and whether you had stopped before being hit. Insurers sometimes treat a chain crash as one event, and the sequence is what shows your own share was nil.

The other driver blames you: what now?
A fault finding isn't final just because the insurer has made it. Most insurer decisions can go to internal review, generally within 28 days of receiving the decision, and then to the Personal Injury Commission. Before you accept a finding that you were mostly at fault, have someone look at whether the evidence supports it, because so much turns on that line.

Frequently asked questions
Not automatically, although it can help. A traffic fine or a criminal charge is a separate process from your claim, and the insurer generally looks at all the evidence rather than relying on it alone. A conviction can be strong support for your account. A charge that is dropped, or no charge at all, doesn't mean the other driver wasn't at fault. Keep a copy of any police paperwork you receive.
Not by itself. An apology can be mentioned, but insurers decide fault on the evidence as a whole: police records, damage patterns, photos, footage and witnesses. People apologise for many reasons, and drivers sometimes change their account later. Write down exactly what was said and when, then collect the harder evidence. If fault is disputed, those records will count for more than the apology.
Generally, yes. You claim against the CTP insurer of the vehicle at fault, which here is the Green Slip insurer of your friend's car. The claim is against the insurer, not against your friend personally. Passengers are rarely found at fault, though contributory negligence can still be raised in limited cases, for example if you knew the driver had been drinking. Your friend may be asked for their account, which is normal.
If your claim is against that vehicle's CTP insurer, you'll deal with them to run it, so a call is normal. Stick to facts, don't guess about speeds or injuries you're unsure of, and keep a note of the call. If you're asked for a detailed recorded statement about how the crash happened, you can ask for time to get advice first, especially if they're questioning who caused it.
Keep the original file safe first. Many dashcams record over older footage, so copy it to another device or cloud storage straight away, without trimming or editing it. Tell the insurer you have footage, and give it to police if they're investigating. If fault is disputed, the footage can be one of the strongest pieces of evidence you have, because it shows the crash rather than anyone's memory of it.
It can reduce your claim, but it usually doesn't end it. Not wearing a seatbelt is a classic example of contributory negligence. Weekly payments after 52 weeks may be reduced for it, and any damages can be reduced too. How much depends on the evidence, including medical opinion on whether a seatbelt would have changed your injuries. Get advice before you accept the percentage the insurer puts forward.
