When you’re injured and someone else is at fault, compensation isn’t calculated as a single figure. It’s broken into categories called “heads of damage,” and each one is assessed separately under its own rules. Getting one wrong (or missing it entirely) can cost you thousands.
Heads of damage in a personal injury claim are the separate categories of compensation an injured person can pursue under Australian law. Each head covers a different type of loss, from pain and suffering to lost wages and out-of-pocket medical costs, and is assessed independently based on the evidence available. In Western Australia, the Civil Liability Act 2002 and common law principles govern how most of these categories are calculated.
Most people I’ve worked with don’t realise these categories exist until they’re already deep into a claim. They picture one lump sum. It doesn’t work that way. Each head gets argued on its own merits, with its own evidence, and the insurer will push back on every single one. If you don’t know what you’re entitled to claim, you’ll settle for less than you should.
This article covers the main heads of damage in WA personal injury claims. It won’t cover workers’ compensation statutory benefits (that’s a different scheme with its own rules) or criminal injuries compensation under the Criminal Injuries Compensation Act 2003.
How Are General Damages Calculated in Western Australia?
General damages compensate you for pain, suffering, and loss of enjoyment of life caused by your injury. This is the head most people think of first, and it’s also the one where WA law creates the most confusion.
Under Section 9 of the Civil Liability Act 2002 (WA), general damages use a sliding scale with built-in thresholds. If your general damages are assessed at or below Amount A (currently $23,500), you receive nothing for this head. If the assessed amount falls between Amount A and Amount C ($68,000), the award is reduced by Amount A. So if your pain and suffering is valued at $40,000, you’d actually receive $16,500.
That catches people off guard. You can have a genuine injury with ongoing pain and still fall below the threshold. I’ve seen it happen repeatedly with soft tissue injuries where the medical evidence supports real, lasting discomfort but doesn’t push the assessment above the line.
Evidence for general damages typically includes medical records and specialist reports, opinions on whole person impairment, and your own detailed account of how the injury has changed your daily life. The difference between a $25,000 assessment and a $70,000 assessment often comes down to how thoroughly the pain and suffering is documented in those reports.
The general damages calculation method also changes depending on the type of claim. Motor vehicle accident claims through the Insurance Commission of Western Australia (ICWA) follow a different process than public liability claims or common law workers’ compensation matters. The legislation that applies to your specific situation shapes both the formula and the cap.
Economic Loss: Past Income and Future Earning Capacity
Economic loss covers income you’ve already lost because of the injury and income you’re expected to lose going forward. For many claimants, this is the biggest single head of damage.
Past economic loss is the more straightforward calculation. You compare what you were earning before the injury to what you earned (or couldn’t earn) after it. Pay slips, tax returns, and employment records do most of the work here.
Future economic loss is where claims get genuinely complicated. You’re trying to predict what someone would have earned over the rest of their working life. That involves looking at pre-injury earning trajectory (were you in line for a promotion?), how long you would have kept working, your actual earning capacity now, given the injury, and medical evidence about whether your condition will improve.
Most people undervalue this head. They focus on what they’re losing right now and forget about lost superannuation contributions, missed promotions, and reduced career options over 10 or 20 years. I’ve seen cases where the future economic loss component was worth more than every other head combined. According to research published by the Bureau of Justice Statistics in the US, self-represented claimants settle for roughly 30% to 50% less than those with legal representation, and future losses are where the biggest gap appears.
Actually, let me reframe that. The real risk isn’t just undervaluing future income. It’s settling before you’ve reached maximum medical improvement. If you accept a payout before your doctors can say “this is as good as it gets,” you’re guessing at future losses. And insurers are betting you’ll guess low.
What Counts as Special Damages?
Special damages cover the actual money you’ve spent (or will spend) because of the injury. Think of these as your documented, out-of-pocket costs.
This includes medication, medical appointments and specialist consultations, diagnostic imaging like X-rays and MRIs, travel to and from treatment appointments, and equipment or home modifications required because of the injury.
Special damages can also include amounts paid by third parties that need to be repaid when the claim settles. Medicare and private health insurance refunds are common examples. If Medicare covered your surgery, that cost typically comes out of your final settlement figure.
Keep every receipt. I say this in every initial consultation, and roughly half the people I speak to haven’t been doing it. The difference between a well-documented special damages claim and a poorly documented one can be $5,000 to $20,000 on a moderate injury. A shoebox of receipts is better than nothing, but a spreadsheet is better than a shoebox.
Gratuitous Care From Family and Friends
If your family or friends have been helping you with daily tasks because of your injury, that unpaid help has a dollar value. This head lets you claim the commercial equivalent of services provided for free.
Say you can’t cook, clean, or drive yourself to appointments. Your partner takes on all of that. Under WA law, you can claim what it would cost to hire someone to perform those same tasks.
But there’s a minimum threshold. Before you can include gratuitous care in your claim, you need to show at least six hours of care per week for at least six consecutive months. Fall short of either requirement, and this entire head drops to zero. No partial credit.
One thing most articles on this topic won’t tell you: the six-hour threshold doesn’t have to be dramatic. Driving someone to three medical appointments a week, helping them shower, preparing meals, and doing the grocery shopping adds up quickly. The trick is recording it. A simple logbook or diary noting what was done, by whom, and for how long is the best evidence you can produce. Statements from the people helping you back it up.
Gratuitous care isn’t available in workers’ compensation common law claims in WA. That’s a gap that trips people up when they’re comparing entitlements across different claim types.
Paid Care and Support Services
Where you’ve actually hired someone to help because of the injury (a cleaner, a gardener, a professional carer), that cost falls under paid care. Unlike gratuitous care, there’s no minimum threshold.
If you paid for it and it’s related to your injury, you can claim it. You’ll need receipts, invoices, and sometimes a statement from the provider confirming what services they delivered and why. The connection between the service and the injury needs to be clear. Paying someone to mow the lawn because you broke your leg? Claimable. Paying for a house renovation you’d been planning anyway? Not claimable.
How Do Interest and Discounts Work?
Interest recognises that you’ve been out of pocket since the injury happened. You had medical bills, lost wages, and couldn’t use that money while the claim dragged on. An interest component compensates for that delay.
On the flip side, future losses get discounted. The reasoning is straightforward: you’re receiving a lump sum now for losses that would have played out over years or decades. In WA, future losses are typically discounted at 5% per year, applied as a multiplier based on the number of years the loss is expected to continue.
This is one area where math matters enormously. A small change in the discount calculation on a claim with 20 years of projected future losses can shift the total payout by tens of thousands of dollars. It’s also an area where insurers and claimants regularly disagree on the numbers. If you’re looking at how these figures feed into a formal claim document, understanding how a schedule of damages works will give you a clearer picture.
Why the Parties Often Disagree on the Amount
Even when both sides have the same medical reports, the same pay slips, and the same receipts, they’ll often land on very different numbers.
That’s because each head of damage involves judgment calls. The insurer might argue your knee pain isn’t related to the accident. Your lawyer says the medical evidence says it is. The insurer’s economist projects you’ll return to full-time work in 12 months. Your vocational expert says three years is more realistic.
These disagreements are most common where the link between the injury and the claimed loss isn’t black and white, or where the evidence involves predictions about the future. And that’s the majority of claims. According to the Insurance Commission of WA, they cover reasonable and necessary expenses, but “reasonable” is exactly the kind of word two lawyers can argue about for months.
Here’s the contrarian take most people in this industry won’t say plainly: insurers aren’t trying to give you a fair deal. They’re managing a claims book. Initial offers routinely undervalue the non-economic heads (pain and suffering, future loss) by a significant margin because most claimants don’t have the documentation or the patience to push back. Having a team that understands your situation and can build the evidence for each head separately changes the outcome.

Frequently Asked Questions
What are the main heads of damage in a personal injury claim?
The main heads of damage are general damages (pain and suffering), past and future economic loss (lost income and earning capacity), special damages (out-of-pocket expenses like medical bills and travel), gratuitous care (unpaid help from family and friends), and paid care (professional services you’ve hired because of the injury). Interest on past losses and discounts on future losses are also applied. Each head is assessed separately using different types of evidence.
How are general damages calculated in Western Australia?
In WA, general damages are assessed under Section 9 of the Civil Liability Act 2002. The Act uses a sliding scale with thresholds. If general damages are assessed at or below $23,500 (Amount A), no award is made. Between $23,500 and $68,000 (Amount C), the award is reduced by Amount A. Above Amount C, a different formula applies. Medical reports and evidence of impact on daily life are the primary inputs.
Can I claim compensation for unpaid help from family members?
Yes, this falls under the gratuitous care head of damage. In WA, you can claim the commercial value of unpaid services provided by family or friends. But you must meet a minimum threshold of six hours of care per week for at least six consecutive months. Keeping a logbook of the help provided is the best way to support this part of your claim.
What is the difference between special damages and general damages?
Special damages are quantifiable, out-of-pocket costs tied to the injury (medication, medical appointments, imaging, travel, equipment). General damages cover the non-financial impact, including pain, suffering, and loss of enjoyment of life. Special damages are proven with receipts and invoices. General damages rely on medical opinions and your personal evidence about how the injury has changed your daily life.
How is future economic loss calculated in a personal injury claim?
Future economic loss estimates what you would have earned over the rest of your working life had the injury not occurred, minus what you’re now expected to earn with the injury. It factors in pre-injury career trajectory, medical prognosis, and work-life expectancy. In WA, future losses are discounted at 5% per year because you receive the funds as a lump sum upfront. This head is often the most disputed because it involves predictions about the future.
Do I need a lawyer to claim heads of damage?
You don’t legally need one, but research consistently shows that represented claimants receive significantly higher settlements than self-represented ones. The gap is largest on future economic loss and general damages, where legal and medical expertise directly affects the assessed value. Many personal injury firms in WA (including Soul Legal) work on a no-win, no-fee basis, so there’s no upfront cost.
Are personal injury compensation payouts taxable in Australia?
Generally, no. Compensation for personal injury (including all heads of damage) is not taxable under Australian tax law. The Australian Taxation Office treats lump sum payments for personal injury as non-assessable income. However, if you invest the payout and earn interest or returns on it, that investment income is taxable like any other.
