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 Silverdale. It won't tell you what your claim is worth, because no honest page can. It will help you ask the right questions.

Serious injury care and records near Silverdale
If a serious injury means trips along the Hume Motorway or Narellan Road for specialist care, keep a log. The injury's effect on getting around is part of the picture. If you were admitted to Nepean Hospital after the crash, the admission notes, scans and specialist letters made there are often the first evidence of how serious the injury is. Ask for copies, or ask your GP to obtain them. A serious injury can make every trip to Penrith 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.
For people in the Wollondilly Shire 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.

Serious injury: when legal advice helps
Serious injuries are where legal advice most often earns its place, because the stakes and the rules are both higher. Even so, not every serious injury claim needs a lawyer at every stage. Here is a general guide.
Often worth talking to a lawyer
- You have a fracture, a tear, nerve damage or a brain injury
- Your injury may stop you returning to the work you did before
- The insurer has classed your injury as threshold and your doctors disagree
- Another driver was at fault and a damages claim may be possible
You may not need one
- The injury has settled with no lasting effect on your work or daily life
- You want general scheme information that CTP Assist can give
- You were mostly at fault, so no damages claim is open to you
If you're not sure your injury has been fully investigated, a doctor experienced with CTP can help. We can suggest doctors and allied health familiar with the Certificate of Fitness and serious injury care.
Not quite your situation?
- Hurt at work, or in a crash while you were working? That is usually a workers compensation claim first, which is a different scheme from CTP. Tell us what happened and we can point you to the right help. Free claim check

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.

Mental health after a serious crash
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.

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%.
It's easy to overstate the 10% line. You don't need more than 10% WPI to claim damages for past and future loss of earnings; you need an injury that's more than threshold, another driver at fault, and not to have been mostly at fault yourself. The 10% line decides pain and suffering, and it also affects some timing rules for a damages claim.

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.
Getting the classification right early helps. If you have symptoms that could point to nerve involvement or a tear, such as numbness, weakness, locking or a joint giving way, describe them to your doctor. Whether tests are needed is a medical decision. If a diagnosis changes, make sure the insurer has the new evidence, because the classification may need to change with it.
Check the date of your accident
The scheme has been amended over time, most recently for accidents from 1 April 2023. Rules change, so check the current rules for your accident date.

Serious injury and your future earnings
Earning capacity compares what you could have earned without the injury with what you can realistically earn now. For a tradesperson with a damaged shoulder, or an office worker with a brain injury, that gap can be large and long-lasting. Record every change to your working life: hours, duties, roles you can no longer do. Those facts sit alongside the medical evidence.

When whole person impairment is measured
There's usually no single moment when WPI is measured. Opinions may come from treating doctors, from doctors the insurer arranges, and, where the two sides disagree, from a medical assessment through the Personal Injury Commission. Timing matters, because injuries can improve or worsen for months. A lawyer can advise whether an assessment is premature before you rely on it.
- Whether the injury has stabilised
- Changes in your condition since the last report
- Whether you disagree with the result, and the deadline to say so

What shows an injury is serious
Because serious injuries take time to show their full effect, evidence builds in layers. Early records show the injury happened and how bad it was. Later reports show how it has settled and what it has left behind. An independent lawyer can help spot gaps, but the underlying evidence comes from your treatment. Getting good care is also how good evidence is made.
- Hospital admission and discharge records
- Imaging reports, such as X-ray, CT or MRI, where done
- Every Certificate of Fitness, in order
- Records of how the injury affects your work

Frequently asked questions
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.
Tell your doctor about the change, get it recorded, and make sure the insurer receives the new evidence. An earlier assessment may no longer reflect your condition, and in some circumstances the injury may be looked at again. Whether and how that happens depends on the stage of your claim and the rules for your situation, so this is a good point to get advice.
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.
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.
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.
