The answers affect how long benefits can run and whether damages are possible.

For people in the Northern Beaches Council area, as anywhere in NSW, the test for a serious injury comes from the scheme's rules and your medical evidence, not from where you happen to live.

Is your injury serious enough to get advice?
If your injury is more than threshold, it's worth at least one conversation with someone who knows the scheme. Whether you need more than that depends on your situation. Use these lists as a starting point.
Often worth talking to a lawyer
- You're wondering whether your impairment could be more than 10%
- You have a fracture, a tear, nerve damage or a brain injury
- Your injury may stop you returning to the work you did before
- An impairment assessment is coming up, or you disagree with one
You may not need one
- You were mostly at fault, so no damages claim is open to you
- Your question is about treatment options, not compensation
- The injury has settled with no lasting effect on your work or daily life
Serious injuries need coordinated care. Ask us about doctors and allied health who understand CTP claims, from the Certificate of Fitness to ongoing rehabilitation and psychology.
Not quite your situation?

Threshold injury, or something more serious?
Think of this as a map, not a verdict. It shows the kinds of injury usually treated as threshold, and the findings that may take an injury beyond it. Only the medical evidence in your own claim can place you.
Usually treated as a threshold injury
- Sprains and strains of muscles, tendons or ligaments
- Whiplash-type neck pain with no nerve findings
- Bruising and soft tissue swelling
- A psychological injury the scheme classes as threshold
- Statutory benefits generally up to 52 weeks, for accidents from 1 April 2023
May be more than a threshold injury
- Nerve damage confirmed by a doctor
- A full or partial tear of a tendon, ligament, meniscus or cartilage
- A fracture, which is generally not a soft tissue injury
- A brain injury, or a diagnosed psychological condition beyond the threshold category
- Damages may be possible if another driver was at fault and you weren't mostly at fault
General information, not legal advice, and not medical advice either. The insurer decides on the medical evidence, its decision can be reviewed, and time limits apply.
When an injury counts as serious
Two measurements do most of the work when an injury is serious. One is the threshold line, which separates soft tissue and some psychological injuries from everything else. The other is whole person impairment, a percentage that describes lasting impairment. Between them, they affect how long statutory benefits can run and what a damages claim, if you have one, can include.

What whole person impairment is
Whole person impairment, or WPI, is a percentage that describes how much a lasting injury affects the body as a whole. It isn't a measure of pain, and it isn't a measure of what you've lost. It's a medical assessment made under set guidelines once an injury has stabilised. In a CTP claim, WPI matters mainly for damages: non-economic loss is only available where WPI is more than 10%.
An assessment above 10% opens damages for non-economic loss and changes some timing rules as well. But many people with genuine, lasting injuries are assessed at 10% or less. That doesn't mean the injury isn't real, or that there is no damages claim. Economic loss, such as lost earning capacity, can still be claimed where the other conditions are met.

The threshold line and what takes an injury past it
The threshold line is a medical line drawn by legal rules. Your doctor diagnoses the injury; the scheme's definition decides which side it falls on. Sprains, strains and whiplash without nerve findings usually sit on the threshold side. Confirmed nerve damage, a tear, a fracture or a brain injury generally takes an injury beyond it. The insurer makes the call, and you can challenge it.
Which side you're on matters. For accidents from 1 April 2023, statutory benefits for a threshold injury generally last up to 52 weeks. For accidents between 1 December 2017 and 31 March 2023, the limit was 26 weeks. If your injury is more than threshold and you weren't mostly at fault, benefits can generally continue for longer, and a damages claim may be possible.
Check the date of your accident
The threshold rules and benefit periods depend on when your accident happened. Check which rules apply to your date before relying on any general statement.

The timing of an impairment assessment
In a serious injury claim, impairment often comes into focus well after the crash, once treatment has run its course. The Personal Injury Commission handles medical assessment where the insurer and the injured person disagree. If you think an assessment is wrong, the steps to challenge it are set out separately, and the deadlines are short, so act promptly.
- Whether every injured body part is included
- Scans or tests your doctors have ordered
- Whether you disagree with the result, and the deadline to say so

Psychological injury and the threshold
Serious physical injuries often bring a psychological toll: sleeplessness, anxiety, depression or trauma symptoms. These can be part of your claim in their own right. Tell your doctor how you're coping, and ask about psychology if it would help. Whether a psychological injury is threshold or more is a medical and legal question, and the insurer's decision on it can be reviewed.

Long-term earning capacity
A serious injury can change more than the next few months of work. It can limit the kind of work you can do for years, or permanently. In a damages claim, that is called loss of future earning capacity, and it can be a significant part of a serious injury claim. It generally needs evidence from your doctors, your work history and sometimes vocational experts.

Building the evidence for a serious injury
The most persuasive serious injury claims usually have consistent evidence: the same injuries described the same way, from the hospital to the GP to specialists, with no unexplained gaps in treatment. That consistency comes from telling each doctor the full story and following treatment plans. If a report leaves something out, ask the doctor about it rather than letting it pass.
- Imaging reports, such as X-ray, CT or MRI, where done
- Reports from a treating psychologist or psychiatrist, if any
- Records of how the injury affects your work
- Any impairment assessment, and your response to it

Frequently asked questions
Each injury matters. Your claim should list every injury the crash caused, and your doctors should record all of them, not just the worst. The threshold limits generally apply where all your injuries are threshold injuries, so one injury that is more than threshold can change the whole claim. How several injuries are rated for impairment is technical, so get advice if it matters to you.
More than one person may. Your treating doctors can give opinions, the insurer may send you to a doctor it chooses, and where you and the insurer disagree about the degree of impairment, a medical assessor at the Personal Injury Commission can decide it. Timing matters as much as who: an assessment made before the injury has settled can understate it. To challenge an assessment, see the CTP claim denied page, and act quickly because the deadlines are short.
Generally, yes, for the worsening the crash caused. A pre-existing condition, like arthritis or an old back injury, doesn't stop a claim, but the insurer may argue that some of your symptoms would have happened anyway. Clear evidence helps: records of how you were before the crash, and how you've been since. Tell your doctors about the earlier condition rather than leaving it out.
Not always. Whether scans are needed is a medical decision, and many injuries are diagnosed by examination. Where your doctor recommends imaging, it can show things an examination can't, such as a fracture, a tear or signs of nerve compression, and that can affect how the injury is classified. Keep copies of every imaging report, and don't arrange scans just for the claim.
It could. Tingling, numbness or weakness can sometimes point to nerve involvement, and confirmed nerve damage takes an injury outside the threshold definition. These symptoms can also have other causes, so it's a question for your doctor, who can decide whether tests are needed. Describe the symptoms precisely, note when they started, and make sure any diagnosis reaches the insurer.
Usually, yes, because most whiplash is soft tissue injury to the neck. But not always. If a doctor finds nerve damage, or a full or partial tear of a tendon or ligament, the injury may be more than threshold. Symptoms like arm pain, numbness or weakness are worth describing to your doctor. The insurer decides on the medical evidence, and its decision can be reviewed.
