Key Takeaway: The most common car accident injuries in NSW are whiplash and neck strain, back and disc damage, fractures, head and brain injuries, spinal cord injuries and psychological injury like PTSD. You claim treatment and lost income through the at-fault vehicle’s CTP insurer, and a non-threshold injury assessed above 10% whole person impairment can also attract a lump sum.
Common Car Accident Injuries NSW: Quick Answers
What are the most common car accident injuries in NSW?
The most common car accident injuries are whiplash and neck strain, back and disc damage, fractures, head and brain injuries, spinal cord injuries and psychological injury. Head and neck injuries make up the largest share of injuries we see, and fractures are the most common physical injury type.
A crash can cause one injury or several at once. The list below groups the injuries most often reported after a NSW car accident, from the everyday to the catastrophic.
- •Whiplash and neck injuries
- •Back injuries, including bulging and herniated discs
- •Fractures and broken bones
- •Head and brain injuries
- •Spinal cord and catastrophic injuries
- •Psychological injury and PTSD
- •Shoulder, arm, hip, knee, wrist, hand, ankle and foot injuries
Whatever your injury, if you were hurt in a NSW motor vehicle accident you can claim treatment and lost income through the at-fault vehicle’s Compulsory Third Party (CTP or green slip) insurer under the Motor Accident Injuries Act 2017. For the full picture of how a claim works, see our motor vehicle accident injury claim guide. Call Withstand Lawyers on 1800 952 898 or request a free claim check.
How much compensation can you claim for whiplash and neck injuries after a car accident in NSW?
Whiplash and neck injuries are the most common car accident injury, and are usually classed as threshold (soft-tissue) injuries, so they attract treatment and income support but rarely a lump sum. Where scans confirm nerve or disc involvement, the injury can be non-threshold and a lump sum may follow.
Whiplash happens when a sudden jolt strains the muscles and tendons of the neck and upper back, most often in a rear-end collision. It often does not show on scans yet can be painful for months. Our whiplash compensation claims guide explains how these injuries are assessed and paid.
Can you claim compensation for a back or disc injury from a car accident in NSW?
Yes. Back and disc injuries from a car accident are frequently non-threshold, which means they can support a common law lump sum where whole person impairment is above 10%. Bone, joint, muscle and nerve damage from the neck to the pelvis all fall in this group.
A herniated or bulging disc can press on nerves and cause lasting pain, numbness and reduced work capacity. These injuries often need imaging, review by an orthopaedic doctor and sometimes surgery. See our back injury compensation claims and bulging and herniated disc compensation claims guides for how value is assessed.
What compensation can you claim for fractures and broken bones from a car accident in NSW?
Fractures are the most common physical car accident injury and are non-threshold, so beyond treatment and income support they can attract a lump sum where impairment is above 10%. Multiple fractures or fractures needing surgery tend to carry higher whole person impairment.
Broken bones range from a clean single fracture that heals well to complex breaks that need plates, screws and long rehabilitation. Shoulder, wrist, hip, leg, knee, ankle and foot fractures are all common in car accidents. Our broken bone compensation claims guide sets out what these claims can be worth.
Can you claim compensation for a head or brain injury after a car accident in NSW?
Yes. Head and brain injuries, from concussion to traumatic brain injury, are non-threshold and often carry high whole person impairment, so they can attract substantial compensation. These injuries can affect memory, concentration, mood and the ability to work.
A traumatic brain injury follows a violent jolt or blow that damages brain tissue, and can leave cognitive, physical and emotional effects that last for life. Serious cases may need ongoing care. Our brain injury compensation guide explains how these claims are built and valued.
How much is a spinal cord or catastrophic car accident injury claim worth in NSW?
Spinal cord and catastrophic injuries carry the highest whole person impairment, so they attract the maximum lump sum for pain and suffering plus large future economic loss, and total settlements can reach into the millions. Non-economic loss itself is capped at $691,000.
A spinal cord injury can cause permanent loss of movement or sensation and a lifetime of care needs. Because the future loss of income and care costs can be very large, these claims are valued carefully over time. Our catastrophic injury compensation guide explains the process for the most serious injuries.
Can you claim compensation for psychological injury or PTSD after a car accident in NSW?
Yes. A diagnosed psychological injury such as PTSD, depression or anxiety is treated as non-threshold, so it can support both ongoing benefits and a lump sum where impairment is above 10%. Minor psychological symptoms without a diagnosis are treated as threshold injuries.
Car accidents can leave lasting psychological injury even where physical injuries heal, including flashbacks, sleep problems and a fear of driving. A formal diagnosis and treatment records are key evidence. Our compensation for PTSD guide covers how psychological claims are proven.
What are threshold and non-threshold car accident injuries in NSW?
A threshold injury (previously called a minor injury) is limited to soft-tissue damage and minor psychological symptoms; everything more serious is a non-threshold injury. The difference decides whether you can pursue a common law lump sum.
Only people with a non-threshold injury who were not mostly at fault can claim common law damages, and pain and suffering (non-economic loss) is payable only where whole person impairment is more than 10%, under the Motor Accident Injuries Act 2017. Non-threshold injuries include fractures, spinal and disc damage, nerve damage, brain injury and diagnosed psychological injuries such as PTSD.
What can you claim for a car accident injury: statutory benefits or a common law lump sum?
NSW runs a hybrid CTP scheme with two pathways: no-fault statutory benefits, and a fault-based common law lump sum. Most injured people access statutory benefits, and non-threshold injuries can also pursue a lump sum.
| Feature | Statutory benefits | Common law damages (lump sum) |
|---|---|---|
| What it covers | Treatment, care and lost income while you recover | Past and future economic loss, plus pain and suffering |
| Fault required? | No (first 52 weeks, paid to almost everyone) | Yes, you must not be mostly at fault |
| Injury threshold | None to start; threshold injuries stop at 52 weeks | Non-threshold injury; pain and suffering needs more than 10% WPI |
| Payment type | Ongoing weekly payments and expenses | One-off lump sum |
| Cap | Income support based on pre-accident earnings | Non-economic loss capped at $691,000 |
| Can you receive both? | Yes. Statutory benefits support you now; a lump sum resolves the claim later. | |
Income support is paid at 95% of pre-accident weekly earnings for the first 13 weeks, then 85% if you have returned to some work or 80% if you cannot, per SIRA. Treatment and care are covered while your claim is open. Our CTP claims guide explains how the green slip scheme pays.
How much compensation can you claim for common car accident injuries in NSW?
The lump sum for a car accident injury turns on your whole person impairment, and ranges from little to nothing for a minor soft-tissue injury up to the $691,000 cap for the most serious injuries. The figures below are a guide to the lump sum for permanent impairment and pain and suffering.
| Injury type | WPI % | Payout range | Key factors |
|---|---|---|---|
| Whiplash and soft-tissue neck injury | Under 11% | $18,000 to $95,000 | Usually threshold; treatment and short-term income support |
| Fractures and broken bones | 11% or more | $130,000 to $340,000 | Surgery, recovery time, return to work |
| Back or disc injury with nerve involvement | 11% or more | $150,000 to $380,000 | Ongoing pain, restricted duties |
| Shoulder or knee reconstruction | 11% or more | $190,000 to $430,000 | Reduced work capacity, lasting restriction |
| Head and brain injury | 11% or more | $1 million to $2 million+ | Cognitive effects, ongoing care needs |
| Spinal cord or catastrophic injury | 11% or more | $1.5 million to $2 million+ | Lifelong impairment, no return to work |
These ranges reflect the lump sum for pain and suffering and permanent impairment, which is capped at $691,000. Where an injury also causes large future loss of income, the total settlement can be higher once economic loss is added. Every claim turns on its own facts. In 2024-25 SIRA recorded 14,789 new CTP claims with total payments of $1.7 billion, an average of $70,106 per claim, though serious injuries settle for far more. See our permanent impairment payout amounts guide for how your WPI can affect your payout.
Can you claim for injuries that appear days after a car accident in NSW?
Yes. Delayed-onset injuries are common and can be claimed, provided you see a doctor and have the injury recorded once symptoms appear. Adrenaline and shock often mask pain at the scene, so injuries can surface hours, days or weeks later.
Whiplash, disc injuries and psychological injuries in particular can take time to show. Early medical records that link the injury to the crash are critical evidence, so speak to your doctor as soon as symptoms start and keep every report.
Can you claim for a car accident injury if you were partly at fault in NSW?
Yes. You can claim treatment and income support for the first 52 weeks even if the accident was your fault, but a lump sum requires that you were not mostly at fault and have a non-threshold injury. Fault affects how much you receive, not whether you can start.
If another driver was to blame, your claim is stronger and easier to prove, which our not-at-fault car accident claim guide explains. Passengers sit outside the fault question almost entirely, covered in our car accident passenger claim guide.
What are the time limits for a car accident injury claim in NSW?
NSW motor accident claims have strict deadlines, and missing an early one can quietly cost you thousands. Lodge as soon as you can.
| Deadline | What you must do |
|---|---|
| 28 days from the accident | Lodge your claim to have income support backdated to the accident date |
| 3 months from the accident | Lodge a Personal Injury Benefits Form for weekly benefits and treatment expenses |
| 6 months from the accident | Lodge an Application for Common Law Damages so your eligibility for a payout can be determined |
| 3 years from the accident | File an Application for General Assessment with your supporting documents in the Personal Injury Commission |
Late claims can sometimes still be made with a full and satisfactory explanation, but the earlier you lodge, the stronger your position. Withstand Lawyers can handle the paperwork for you on a no win, no fee basis. Call 1800 952 898.
What are examples of car accident injury payouts in NSW?
Every claim turns on its own facts and these outcomes are not guarantees, but they show how injury type and severity drive value for injured people.
| Client | Injury | Settlement |
|---|---|---|
| Maria, 38, rear-ended at a set of lights | Whiplash with a confirmed herniated disc, ongoing neck pain | $165,000 |
| Josh, 52, T-boned at an intersection | Multiple fractures and a knee reconstruction, lighter duties | $430,000 |
| Aanya, 29, head-on collision on a country road | Traumatic brain injury, unable to return to full-time work | $1,180,000 |
Aanya’s settlement includes a large amount for future loss of earning capacity on top of the capped lump sum for pain and suffering. See more real outcomes on our claims won page.

“Working with Esther has been an absolute blessing during an incredibly difficult time. Anyone who has ever had to navigate an insurance claim knows just how difficult, overwhelming, and anxiety-inducing the entire process can be. Before reaching out to Withstand Lawyers, I was constantly stressed and deeply overwhelmed by the system.
