A car accident in Australia sets off two separate processes: the practical steps you take at the scene and a formal claims process governed by its own rules and deadlines. Getting the first right makes the second far easier to navigate.
Compensation claims run on two tracks: a state-based CTP scheme covers personal injury, while your own comprehensive or property insurance covers vehicle damage. Each has its own reporting requirements and time limits. In New South Wales, for example, a claim for statutory benefits lodged within 28 days of the accident can be backdated to the day it happened, and the standard window to lodge the claim at all is three months, under the Motor Accident Injuries Act 2017.
This guide covers what to do in the immediate aftermath of a crash: when police involvement is required, what to document at the scene, how CTP and comprehensive insurance differ, and the medical and claim deadlines that matter most.
Checking for Injuries: Including the Ones You Can’t Feel Yet
Check for injuries. If you or someone else is injured, dial 000. Adrenaline suppresses many injuries within the first few minutes of a collision, so even if you feel okay, it doesn’t mean that you’re not injured. Soft tissue damage such as whiplash and concussion may only show symptoms within a day or two of the accident, when the adrenaline levels have worn off. Symptoms of these may be headaches, dizziness, problems focusing and neck pain. Don’t brush off an ambulance or the concern of others because you feel okay and want to get the scene over with.
Call the Police and Get It on the Record
Under Australian road rules you generally must report a crash to police if someone is injured, if a vehicle has to be towed, or if a driver refuses to hand over their details. Even when it’s not strictly required, it’s usually worth doing.
A police report, and the event number that comes with it, is an independent record made at the time by someone with no stake in the outcome. Memories drift and stories change. That number doesn’t. If the other driver disputes what happened or won’t cooperate at the scene, experienced car accident lawyers can help you establish an accurate record early.
Gather the Details While You’re Still There
The scene disappears the moment everyone drives off, so collect what you can before that happens: the other driver’s name, licence, phone number, and rego; their insurer, if they’ll share it; the names and numbers of any witnesses; and photos of both vehicles, the damage, the road, skid marks, traffic signs, and the weather.
Take more photos than feels necessary. Get wide shots that show where the cars ended up and close-ups of the damage. If you have a dashcam, save the footage that day; many overwrite themselves on a loop within a matter of days.
Report to Your Insurer and Watch What You Say
Tell your insurer promptly; most policies require it. Stick to the facts you’re sure of: where, when, who was there, and what you can see.
What you want to avoid is editorialising. “I probably should have braked earlier” feels like honesty at the moment. To a claims assessor it reads as an admission, and fault is a legal question that depends on far more than your gut feeling at the scene. State what happened. Skip the self-diagnosis of blame.
Understanding CTP: Injury and Property Damage Are Different Things
In Australia, Compulsory Third Party (CTP) insurance, the “green slip” attached to your registration, covers personal injury arising from a crash. It does not cover the damage to the cars. Panel-beating and write-offs are dealt with through comprehensive or property insurance, a separate track entirely.
CTP schemes are run at the state and territory level under different names and regulators (SIRA in New South Wales, TAC in Victoria, MAIC in Queensland, and others), so the details differ depending on where you were driving. What’s consistent is the principle: if you’re injured in a motor accident, a statutory scheme covers things like medical treatment, a portion of lost income, and, in more serious cases, a lump sum for the lasting impact of the injury. Whether you were at fault affects what you can claim and for how long, but in many schemes even a partly at-fault driver can access some benefits.
Get Medical Attention and Keep Every Piece of Paper
See a doctor even if you think you’re fine, and do it early. A GP visit in the first few days creates a dated medical record that ties your injury to the accident. The longer you wait, the more room an insurer has to argue the injury came from somewhere else.
After that, keep everything: referrals, scan results, physio invoices, receipts for medication, a note of the days you couldn’t work. A compensation claim is only as strong as the evidence underneath it, and injury claims are built on this exact paper trail. It’s dull admin. It’s also the difference between a number you’re offered and a number you can prove.
Time Limits Are Tighter Than You Think and Vary by State
Deadlines depend on where you were driving, and in New South Wales the first one arrives fast: 28 days. Lodge your claim for statutory benefits within 28 days of the accident, and your weekly income payments can be backdated to the day it happened. Lodge later, and, in most cases, those payments only run from the date you claimed; the earlier weeks are gone. There’s a matching 28-day window to report the accident to NSW Police (if an officer didn’t already attend) and give the event number to the insurer.
Then comes the three-month mark: the standard period for lodging the claim itself. You can go past it, but you’ll need a full and satisfactory explanation for the delay, and “I didn’t get around to it” won’t do. Claims for common law damages, the lump sum for a serious injury, run on a longer timeframe, generally around three years, with their own thresholds and a separate process.
Those are the NSW figures under the Motor Accident Injuries Act 2017, and the scheme has been amended more than once, so check the current SIRA guidance or get advice rather than trusting a number you read somewhere. Other states run on different clocks entirely, which is exactly why the deadline is the first thing worth confirming, not the last.
If your injuries are minor, fault isn’t disputed, and the insurer is behaving reasonably, the statutory benefits process is built to work without a lawyer. Other situations pull the opposite way: a serious or lasting injury, a fight over who was at fault, a lowball offer, or an insurer that’s gone quiet. That’s where experienced help earns its keep, someone who knows what a claim is genuinely worth and carries the back-and-forth on your behalf.
