Serious injuries usually mean long claims, with medical evidence gathered over months. It helps to understand the terms early: threshold injury, whole person impairment, non-economic loss. This page covers them in plain language for people in Westleigh. It won't tell you what your claim is worth, because no honest page can. It will help you ask the right questions.

Westleigh: hospitals, specialists and the medical record
If a serious injury means you can no longer drive roads like Pennant Hills Road or the Pacific Highway comfortably, tell your treating doctors. Lasting limits are part of the medical picture. Serious injuries are often first assessed at a hospital such as Hornsby Ku-ring-gai Hospital. Early findings there, especially of nerve damage, fractures or a head injury, can matter to whether the injury is more than threshold. A serious injury can make every trip to Hornsby a major effort. Claim help can stay at home, where the check is done by phone and online and documents can generally be signed without travelling.
Living in the Hornsby Shire Council area doesn't change the rules on serious injuries: the threshold line and whole person impairment work the same way across NSW. What differs from person to person is the medical evidence.

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
- An impairment assessment is coming up, or you disagree with one
- You have a fracture, a tear, nerve damage or a brain injury
- You have a psychological injury as well as a physical one
- Another driver was at fault and a damages claim may be possible
You may not need one
- You want general scheme information that CTP Assist can give
- The injury has settled with no lasting effect on your work or daily life
- Your injury is healing as expected and should resolve fully
With a serious injury, the right treating team matters for recovery and evidence alike. We can point you to doctors and allied health experienced with CTP, including GPs who complete the Certificate of Fitness.
Not quite your situation?
- Injured at work rather than on the road? That is usually a workers compensation claim, which runs under different rules from CTP. The free claim check can point you to the right help. Free claim check

Which side of the threshold line your injury may fall
Where an injury falls against the threshold line affects how long statutory benefits can last and whether damages are possible. The comparison below is general. Symptoms alone don't decide it; the medical diagnosis does.
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.

Whole person impairment, explained
People are often surprised by how technical WPI is. It is assessed under guidelines that rate specific impairments, such as lost movement in a joint, and express the result as a whole-body percentage. More than 10% is the key line in CTP claims, because damages for non-economic loss, meaning pain and suffering, are only available above it. Loss of earnings doesn't need that level.
Because so much can turn on a few percentage points, WPI assessments are often contested. Your treating doctors, the insurer's chosen doctor and, if there's a dispute, a medical assessor through the Personal Injury Commission may reach different figures. Keep every report, and get advice before accepting an assessment you think is wrong.

Serious injury and your future earnings
Weekly payments cover lost income for a limited time. For a serious injury, the bigger question is the future: will you be able to return to your old job, at the same hours and pay? If not, a damages claim may include past and future economic loss, provided the conditions for damages are met. That part of a claim doesn't depend on WPI above 10%.

When the injury isn't only physical
The scheme treats psychological injury seriously, but it still sorts it by diagnosis. A threshold psychological injury is generally handled like a threshold physical one. A more serious diagnosed condition may take the claim beyond the threshold. Because the difference turns on the diagnosis, the opinion of a treating psychiatrist or psychologist can matter a great deal.

Threshold injuries and beyond
The definition works by exclusion. An injury is generally threshold if it is soft tissue damage with no nerve damage and no torn tendon, ligament, meniscus or cartilage, whether the tear is complete or not, or if it is a psychological injury the scheme classes as threshold. Injuries outside that description, such as fractures, torn ligaments or brain injuries, are generally more than threshold.
The line also decides whether common law damages are open. With only a threshold injury, they generally aren't. With a more serious injury, you may be able to claim damages if another driver was at fault and you weren't mostly at fault. That is why a threshold decision is often the most important decision the insurer makes about a serious injury.
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.

Who assesses impairment, and when
Impairment is generally assessed once an injury has stabilised, meaning it's unlikely to change much with further treatment. Assessing too early can understate a serious injury. The insurer may arrange an assessment, your own doctors may give opinions, and if the insurer and you disagree about the degree of impairment, the Personal Injury Commission can carry out a medical assessment.
- Whether the injury has stabilised
- Whether every injured body part is included
- Scans or tests your doctors have ordered

What shows an injury is serious
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.
- Hospital admission and discharge records
- Imaging reports, such as X-ray, CT or MRI, where done
- Every Certificate of Fitness, in order
- Reports from a treating psychologist or psychiatrist, if any

Frequently asked questions
It can. The insurer's decision is based on the evidence it has at the time. If a new diagnosis comes to light, such as nerve damage or a tear, the insurer can be asked to look at the classification again. If you disagree with a decision, there's a formal process to challenge it, starting with an internal review, and the CTP claim denied page explains those steps and their deadlines.
Tell every doctor about it, even if it seemed mild at first. A brain injury isn't a soft tissue injury, so a diagnosed brain injury is generally more than threshold. Symptoms such as headaches, memory problems, fatigue or changes in mood can take time to show and are easy to put down to stress. Record them, and ask your GP whether further review is needed.
Generally, no. A threshold injury is generally a soft tissue injury, and a broken bone isn't soft tissue. So a fracture caused by the crash will usually take the injury beyond the threshold, although the insurer still decides on the medical evidence. If you have a fracture along with soft tissue injuries, make sure the fracture is clearly recorded on every certificate and report.
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.
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.
Yes. Psychological injuries caused by the crash can be claimed along with physical injuries. Some are classed as threshold injuries and others are not, depending on the diagnosis. Tell your GP how you're coping, including sleep, mood and any fear of travelling, so it's recorded. If you're referred to a psychologist or psychiatrist, their reports become part of the evidence.
