Yes, you can still make a personal injury claim in Western Australia even if you were partly at fault. Under the Civil Liability Act 2002 (WA), your compensation gets reduced by your percentage of fault, but it doesn’t disappear entirely. If the other party owed you a duty of care and breached it, you have a right to pursue a claim regardless of your own contribution to the accident.
A personal injury claim where you share some blame is one of the most common situations we see in WA. It’s also one of the most misunderstood. Most people assume any fault on their side wipes out the entire claim. That’s wrong, and it costs injured Australians real money every year. In WA, the law uses a system called contributory negligence, where a court or insurer works out your share of responsibility and reduces your payout by that amount. If you’re 20% at fault on a $100,000 claim, you still walk away with $80,000.
This article covers how fault is determined in WA personal injury claims, what contributory negligence actually means in practice, how your compensation gets calculated, and when you should get a lawyer involved. It won’t cover workers’ compensation statutory entitlements (those have their own rules) or criminal injury claims, which fall under separate legislation.
How Does Fault Work in a Personal Injury Claim in Western Australia?
Fault in WA personal injury law isn’t a simple yes-or-no question. It’s a percentage.
The Civil Liability Act 2002 (WA) sets out the rules. Section 5B covers the general principles for duty of care, and Section 5K deals with contributory negligence. Together, these sections create the framework courts use to split responsibility between everyone involved in an accident.
Here’s what a court looks at when deciding fault:
- Did the other party owe you a duty of care?
- Did they breach that duty by acting unreasonably?
- Did that breach cause your injuries?
- Did your own actions contribute to the harm?
The first three questions determine whether you have a valid claim at all. The fourth question determines how much your payout gets reduced.
I’ve seen cases where a client assumed they’d get nothing because a police report listed them as partly responsible. Witness statements and additional evidence often tell a different story. Police reports carry weight, but they’re not the final word on liability in civil proceedings.
What Is Contributory Negligence in WA?
Contributory negligence is when your own actions play a role in causing or worsening your injuries. It doesn’t mean you caused the accident. It means the court found something you did (or didn’t do) contributed to the outcome.
Under Section 5K of the Civil Liability Act 2002 (WA), the standard is what a reasonable person would have done in your position. The court applies the same principles it uses to assess the defendant’s negligence, just flipped around to look at your behaviour.
Common examples in WA claims:
- Not wearing a seatbelt in a car accident (one of the most frequent findings)
- Jaywalking or crossing against a signal before being hit by a vehicle
- Ignoring safety warnings at a workplace
- Using a phone while driving or walking
The Law Reform (Contributory Negligence and Tortfeasors’ Contribution) Act 1947 (WA) is the other key piece of legislation. It confirms that contributory negligence reduces your damages rather than eliminating them. Before this law existed, any fault on your side could wipe out your claim entirely. That’s been the position in WA for decades now, but the old myth persists.
And here’s something most articles won’t tell you. Insurance adjusters know that myth works in their favour. I’ve seen adjusters push inflated fault percentages early in the process, banking on the claimant not knowing they can dispute it. A 30% fault finding on a $100,000 claim costs you $30,000. Getting that reduced to 15% puts $15,000 back in your pocket. That’s why understanding common defences in personal injury claims matters before you accept any assessment.
How Is Your Compensation Calculated When You’re Partly at Fault?
This is where the maths gets real. Your compensation is reduced in direct proportion to your fault percentage.
| Your Fault % | Total Damages Assessed | Your Payout |
| 10% | $100,000 | $90,000 |
| 25% | $100,000 | $75,000 |
| 40% | $100,000 | $60,000 |
| 50% | $100,000 | $50,000 |
| 75% | $100,000 | $25,000 |
WA doesn’t have a “bar” threshold like some other jurisdictions. There’s no rule saying “if you’re more than 50% at fault, you get nothing.” Even at 80% fault, you can still recover 20% of your assessed damages. That makes WA more favourable than most modified comparative negligence systems used in other countries.
The types of damages you can claim include:
- Economic loss (lost wages, past and future)
- Medical and rehabilitation expenses
- Pain and suffering (called “non-pecuniary loss” in WA)
- Loss of earning capacity
- Care and assistance costs
According to data compiled by CasePeer in December 2025, most Australian personal injury settlements fall between $3,000 and $75,000, with car accident claims averaging around $37,248. But those numbers shift significantly depending on injury severity and fault allocation. A claim worth $150,000 at zero fault becomes a $105,000 claim at 30% contributory negligence.
Does a Police Report Decide Who Was at Fault?
No. And this is one of the biggest misconceptions in personal injury claims across WA.
A police report records what officers observed at the scene and what parties told them. It’s an important piece of evidence, but it doesn’t bind a court. Courts make their own determination based on the full body of evidence, including witness statements, CCTV footage, medical records, expert reports, and physical evidence from the scene.
I’ve worked on claims where the police report was flatly wrong. One common scenario: a rear-end collision where the lead driver stopped unexpectedly. The police report might note the following driver failed to maintain a safe distance. But if the lead driver stopped for no lawful reason, or their brake lights weren’t working, the fault split looks very different once the full picture comes together.
If the initial report puts you at fault and you don’t challenge it, that percentage often sticks through the insurance process. Insurers rely heavily on police reports during early negotiations. Getting a personal injury lawyer in Western Australia involved early can change the trajectory of your entire claim.
What’s the Time Limit for Filing a Personal Injury Claim in WA?
In Western Australia, you generally have three years from the date of your injury to commence legal proceedings. This applies to motor vehicle accidents, public liability incidents, and general negligence claims under the Limitation Act 2005 (WA).
Three years sounds like plenty of time. It’s not.
Building a strong personal injury claim takes months of gathering medical evidence, arranging independent examinations, and negotiating with insurers. If you wait two and a half years to contact a lawyer, you’ve left almost no room to build a proper case. I’ve seen good claims fail simply because the claimant ran out of time.
There are exceptions for minors (under 15 in WA, who get six years) and for people who weren’t immediately aware their injury was connected to someone else’s negligence. But these exceptions are narrow. Don’t assume they apply to you without getting legal advice.
For motor vehicle claims specifically, you need to notify the Insurance Commission of Western Australia (ICWA) as soon as possible after the accident. Delays in notification can create complications, even if you’re technically still within the three-year window.
Should You Hire a Lawyer if You Were Partly at Fault?
Probably, yes. And I’ll tell you why the “probably” matters more than you think.
If your injuries are minor and the fault split is clear (say, a $5,000 claim where you’re obviously 10% at fault), the legal fees might not make financial sense. You’d potentially spend more on representation than the difference a lawyer could negotiate.
But for anything above that threshold, the numbers usually favour getting professional help. Here’s the reality. Insurance companies have teams of adjusters whose job is to minimise payouts. When contributory negligence is on the table, they have a built-in tool to push your settlement down. A personal injury lawyer understands what evidence shifts fault percentages and how to challenge inflated findings.
Most personal injury lawyers in WA work on a no win, no fee basis. Standard contingency fees typically sit between 25% and 33% of the recovery. If you don’t recover anything, you don’t pay legal fees. That arrangement removes the upfront financial risk for people who are already dealing with injury-related expenses.
According to IBISWorld’s 2025 industry analysis, the personal injury legal sector generates roughly $61.7 billion annually in the US alone. That’s not because lawyers are creating claims out of thin air. It’s because the gap between what insurers initially offer and what injured people actually deserve is massive. The same dynamic plays out in Australia, just at a smaller scale.
What Evidence Helps Reduce Your Fault Percentage?
The fault percentage you’re assigned isn’t set in stone. It’s an assessment, and assessments can be challenged with the right evidence.
Evidence that can shift the fault split in your favour:
- Dashcam or CCTV footage showing the other party’s actions
- Independent witness statements that contradict the initial report
- Expert accident reconstruction reports
- Medical evidence showing your injuries are inconsistent with the alleged fault scenario
- Phone records (proving you weren’t on your phone, for instance)
- Maintenance records (for vehicle defects or property hazards)
The strongest personal injury claims I’ve seen are the ones where the claimant started collecting evidence immediately. Photos of the scene, names of witnesses, timestamps on everything. That raw documentation often becomes the foundation that prevents common post-injury mistakes from derailing the case.
Actually, let me reframe that. The single most valuable thing you can do after an accident where fault is disputed is write down exactly what happened while it’s fresh. Not a polished statement. Just your raw account, with times, locations, and what you saw. Courts give more weight to contemporaneous notes than to recollections pieced together months later.
How Does WA Compare to Other States on Fault Rules?
Not all Australian states handle contributory negligence the same way. WA sits in a relatively claimant-friendly position compared to some international systems, but the differences between states matter if your accident crossed jurisdictions.
| State/Territory | System | Key Difference |
|---|---|---|
| WA | Proportionate liability (CLA 2002) | No fault threshold bar. Recovery is possible at any fault level. |
| NSW | Modified system (CLA 2002 NSW) | The court can reduce damages by up to 100% if just and equitable. |
| QLD | Contributory negligence applies | No specific threshold bar, but courts have wide discretion. |
| VIC | Wrongs Act 1958 | Similar proportionate approach to WA. |
| SA | CTP scheme with fault assessment | CTP benefits depend on fault determination by the insurer. |
The key takeaway for WA claimants: you’re not automatically locked out of compensation because you made a mistake. The law recognises that accidents usually involve shared responsibility, and the system is designed to account for that.
What Happens if the Other Party Was Uninsured?
This comes up more often than people expect. If the at-fault driver doesn’t have CTP insurance (which is compulsory in WA, so this usually means an unregistered vehicle), you can still make a claim through the Insurance Commission of Western Australia’s nominal insurer scheme.
The process is different. Filing a claim against an unknown or uninsured driver requires you to follow specific procedures and timeframes. But the right to compensation still exists, even if you share some fault for the accident.
For non-vehicle claims (slip and fall injuries, for example), the absence of insurance on the other party’s side makes things harder. You may need to pursue the claim directly against the individual or business, which raises questions about whether they have assets to satisfy a judgment. A lawyer can advise whether the claim is worth pursuing given those practical realities.
One Thing Most People Get Wrong About Fault in Personal Injury Claims
The biggest mistake isn’t legal. It’s psychological.
People who think they were partly at fault often don’t pursue a claim at all. They assume the system is all-or-nothing. In reality, WA’s contributory negligence laws exist specifically to handle these grey-area situations. The law doesn’t expect perfection from anyone. It expects reasonableness.
If you were in an accident in Western Australia and you’re unsure whether your own actions affect your right to compensation, the answer is almost certainly that you still have options. The question isn’t whether you can claim. It’s how much your payout will be adjusted. And that number, more often than not, depends on the quality of your evidence and the team working behind the scenes to present your case properly.

Frequently Asked Questions
Can you still claim compensation in WA if you were 50% at fault?
Yes. Western Australia doesn’t have a threshold that bars your claim at any specific fault level. If you’re assessed at 50% fault on a $100,000 claim, you’d receive $50,000. The court reduces your payout by your exact percentage of responsibility under the Civil Liability Act 2002 (WA).
Does contributory negligence apply to all personal injury claims or just car accidents?
It applies to all personal injury claims in WA, not just motor vehicle accidents. Slip and fall claims, public liability cases, medical negligence, and workplace injury claims (specifically common law claims against a negligent party) can all involve contributory negligence findings. The same legal test under Section 5K of the CLA applies across the board.
What if the police report says I was at fault for the accident?
A police report is one piece of evidence, not a binding legal determination. Courts assess fault independently using the full range of evidence, including witness statements, CCTV footage, expert reports, and medical records. If you believe the police report is inaccurate, a personal injury lawyer can help you gather evidence to dispute it.
How long do I have to file a personal injury claim in Western Australia?
You generally have three years from the date of your injury to commence legal proceedings under the Limitation Act 2005 (WA). Exceptions exist for minors under 15 (who get six years) and for cases where the connection between the injury and negligence wasn’t immediately apparent. For motor vehicle claims, you should notify the Insurance Commission of Western Australia as soon as possible.
Will hiring a lawyer cost me money upfront for a personal injury claim?
Most personal injury lawyers in WA offer no win, no fee arrangements. You don’t pay legal fees unless your claim succeeds. Standard contingency fees in Australia typically range from 25% to 33% of the recovery. Some firms offer lower rates for cases that settle before court proceedings are filed.
Can an insurer assign me a higher fault percentage than I actually deserve?
Yes, and it happens frequently. Insurers make initial fault assessments based on available evidence, and they have a financial incentive to assign higher fault percentages to claimants. You’re not obligated to accept their assessment. Independent evidence and legal representation can often reduce the fault percentage, which directly increases your payout.
What evidence do I need to dispute my fault percentage in a personal injury claim?
The strongest evidence includes dashcam or CCTV footage, independent witness statements, accident reconstruction reports, medical records showing injury patterns inconsistent with the alleged fault scenario, and contemporaneous notes you wrote shortly after the incident. Phone records and vehicle maintenance records can also shift the fault assessment in your favour.
