Yes. In Australia you can dispute a denied car insurance claim for free. First lodge an internal complaint (IDR) with your insurer, who generally must respond within 30 days. If that fails, escalate to AFCA, the free, independent ombudsman, whose decisions bind the insurer but not you.
Your car insurance claim has been denied. Maybe it's wear and tear, maybe it's something you "didn't disclose," maybe the payout on your write-off is thousands less than the car is worth. It feels final. It usually isn't. In Australia you have a free, independent dispute path that the insurer is bound by, and a denial letter is the start of that process, not the end of it.
This is a plain-English, consumer-side guide to disputing a denied car insurance claim in Australia: why claims get knocked back, how to tell whether yours is genuinely worth fighting, and the exact free steps to escalate it. It is general information to help you help yourself, not legal advice, and it isn't tailored to your specific circumstances. For advice on your own matter, the free services in Section 11 are the place to start.
- Get the denial in writing and ask for the evidence the insurer relied on.
- Lodge an internal complaint (IDR) with your insurer — they generally must respond within 30 days.
- Escalate to AFCA, the free, independent ombudsman, if IDR doesn't fix it.
- Tribunal or court is the last resort — and you keep that right even after AFCA.
You don't need a lawyer to do any of this, and it costs you nothing to lodge.
1. First, don't panic — denied claims are often worth disputing
A denial is an insurer's decision. It is not a court ruling, and it is not the last word. Insurers get decisions wrong, apply exclusions too broadly, and sometimes can't actually prove the thing they're relying on. The dispute system exists precisely because that happens.
Here's the honest, verifiable picture. In 2024–25, 73% of complaints AFCA closed before reaching a formal decision were resolved by agreement or in the consumer's favour (across all financial products, not just car insurance). That is not a "win rate" — it counts cases settled by negotiation before any ruling, and most complaints close at that earlier stage. But it tells you something important: once a complaint is properly escalated, a large share get resolved without the consumer ever needing a formal determination. Source: AFCA annual review data.
There's a sector-specific signal too. The independent Consumer Action Law Centre has reported that a large share of wear-and-tear and maintenance-based denials are overturned on review — roughly half, on the General Insurance Code Governance Committee's findings. So a "wear and tear" knock-back, in particular, is one of the more contestable grounds out there.
- Don't accept the denial verbally or in writing yet. Don't sign anything that closes the claim.
- Get the reasons in writing. Email the insurer and ask for the denial reason in full, plus the documents and reports they relied on.
- Save everything. Photos, the PDS (product disclosure statement), your policy schedule, emails, text messages, repair quotes, dates.
- Lodge an internal complaint (IDR) — see Section 5. This starts the clock and is your gateway to AFCA.
One more reassurance about scope: AFCA covers comprehensive car insurance, claim denials, valuation and write-off disputes, delays, cancellation, excess and no-claim-bonus problems. (Compulsory Third Party / CTP is the one motor product that sits outside AFCA's remit.) For almost every comprehensive-policy dispute, the free path below is open to you.
2. Why car insurance claims get denied in Australia
There's no official ranked list of denial reasons, so treat these as the common ones, not a league table. MoneySmart groups most denials into a few buckets: the event isn't covered, a condition of the policy was broken, or the car wasn't maintained — plus non-disclosure, specific exclusions, and late notification. Source: MoneySmart (ASIC).
- Non-disclosure or misrepresentation — you allegedly didn't tell the insurer something they asked about (a prior accident, a modification, a licence issue). This is one of the most contestable grounds, because the law puts the burden on the insurer. See Section 8.
- Policy exclusions — the claim falls under a specific carve-out in the PDS. Whether that exclusion is clear and unambiguous matters a lot.
- Wear and tear / pre-existing damage — the insurer says the damage was gradual or already there, not "sudden and accidental." Frequently contestable, especially where the insurer can't prove the cause.
- At-fault / liability disputes — you disagree with who was found at fault, which can hit your excess and no-claim bonus.
- Drink or drug driving — generally hard to dispute where impairment is proven, but the law is more nuanced than "you blew over, claim gone" (see Section 10).
- Unlisted or excluded driver — someone not covered by the policy was driving.
- Lapsed policy / missed premium — turns on whether the policy had actually been cancelled or was merely overdue.
- Hail / storm "avoidable" denials — the insurer says you ignored a warning, or the damage was pre-existing or wear-and-tear rather than sudden.
- Total-loss valuation — the claim is accepted but the payout offered for a written-off car is too low. See Section 9.
3. Is my denial actually contestable?
This is the question every other guide skips. Not every denial is worth fighting, and being honest about that saves you weeks of effort. The table below is a general guide to how contestable common grounds tend to be. It is not a prediction about your case — the facts and your specific policy wording decide everything — but it's a realistic starting point.
| Ground for denial | How contestable | Why |
|---|---|---|
| Non-disclosure on a vague or unasked question | Strong | For consumer policies taken out or renewed since 5 Oct 2021, you only have a duty to take reasonable care not to make a misrepresentation — and the insurer must prove you breached it. If they never clearly asked, or the question was ambiguous, the denial is shaky. |
| Modification unrelated to the loss (e.g. an undeclared mod, but the car burnt in a bushfire) | Strong | The insurer's remedy is tied to the actual effect of the non-disclosure. Where the undisclosed thing had nothing to do with how the loss happened, refusing the whole claim is often disproportionate and challengeable. |
| "Wear and tear" where the insurer can't prove causation | Strong | Ambiguity is read against the insurer, and they must show the exclusion actually applies. Independent findings suggest a large share of wear-and-tear denials are overturned on review. |
| Lowball total-loss valuation | Strong | Market value is a question of evidence. If you can produce comparable sale listings showing a higher figure, AFCA has reversed insurer valuations on the evidence. |
| Unreasonable delay with no decision | Strong | Insurers must decide within set timeframes. Excessive delay is itself a complaint ground, and AFCA can award interest and compensation for the inconvenience. |
| Disputed at-fault / liability finding | Weak–moderate | AFCA reviews whether the insurer's process was fair and reasonable, but it does not determine legal liability for the accident — only a court does that. Worth raising if the process was flawed, but manage expectations. |
| Clear, unambiguous exclusion that plainly applies | Weak | If the PDS clearly excludes the exact thing that happened and the wording isn't ambiguous, there's little to argue. |
| Proven drink/drug driving with impairment | Basically unwinnable | Where impairment and breach are proven, this is one of the hardest grounds. (But "just over the limit" with no proof of impairment is a different question — see Section 10.) |
| Named-excluded or unlisted driver behind the wheel | Basically unwinnable | If the policy clearly excluded that driver, the exclusion usually holds. |
| Proven fraud | Basically unwinnable | Where the insurer can actually prove fraud, the claim fails. (Note: only a small fraction of investigated claims are ultimately declined for fraud — being investigated is not the same as being guilty.) |
4. Step 1 — Get the denial in writing and request the evidence
You cannot dispute a decision you can't see the reasoning for. Before anything else, get the insurer's position in writing and ask for the material they relied on. A short, polite email is enough. Ask for:
- The denial reason in full, in writing, with the exact policy clause or exclusion they're relying on.
- Any assessor, investigator or expert reports that informed the decision.
- Your PDS and policy schedule (the version that applied when you took out or last renewed the policy).
- The underwriting guidelines relevant to your situation (especially for a non-disclosure denial — they show whether they'd have insured you anyway, perhaps at a higher premium).
- Recordings or transcripts of the application call if non-disclosure is the issue — what you were actually asked matters.
Build your evidence file
While you wait, assemble your side. What you need depends on the denial type:
- Wear-and-tear / pre-existing: timestamped photos (before and after), service records, repair quotes. Dated photos have won "pre-existing vs recent damage" disputes.
- Non-disclosure: proof of what you disclosed and when, the second-hand purchase paperwork if you didn't know about a modification, anything showing the question was unclear.
- Total loss: comparable sale listings (same make, model, year, condition, kilometres) showing the market value you're claiming.
- At-fault: witness statements, dashcam footage, a clear written timeline of events.
5. Step 2 — Internal Dispute Resolution (IDR): complain to your insurer
IDR is the insurer's own formal complaints process, and it's a required first step: AFCA generally won't take your case until you've been through it. The good news is there's a hard deadline. Under ASIC's enforceable standard (RG 271), an insurer must give you an IDR response within 30 calendar days in most cases. If the matter is complex and they need longer, they must send you a delay notification — and that notification lets you escalate to AFCA straight away. Source: ASIC RG 271.
Your IDR complaint should be short, factual and specific. State that you're making an internal dispute resolution complaint, set out what was denied, why you disagree (point to the evidence and the relevant law where you can), and what outcome you want. Keep it unemotional and dated.
The free dispute kit includes a fill-in-the-blanks IDR complaint letter you complete and send yourself. It covers the structure insurers respond to: a clear "this is an IDR complaint" header, a space for the claim and policy numbers, the denial reason you're disputing, a prompts list for the evidence and law that applies to common grounds (non-disclosure, exclusions, wear and tear, valuation, delay), and a plain request for the outcome you want plus the 30-day response expectation. It's a general template, not advice — you fill in your own facts and lodge it yourself.
6. Step 3 — Take it to AFCA (the free ombudsman)
If IDR doesn't resolve it (or the insurer misses the deadline), you escalate to the Australian Financial Complaints Authority (AFCA). This is the heart of the consumer-protection system, and a few facts make it powerful:
- It's free for consumers. AFCA is an independent, not-for-profit body funded by its member firms — the insurer pays, not you. (Note: AFCA's service is free; if you choose to hire your own paid representative, that's a separate cost.) Source: AFCA.
- Its decisions bind the insurer, but not you. If AFCA decides in your favour and you accept the determination, the insurer is bound by it. You are not bound — if you're unhappy, you keep your right to go to court. ASIC puts it plainly: "AFCA's decisions are binding on the financial firm, but you do not have to accept it." You usually have around 30 days to accept a determination.
- You don't need a lawyer. The process is designed for ordinary people to use themselves.
The time limits
You generally have to lodge with AFCA within 2 years of the insurer's final IDR response, and within 6 years of when you first knew (or should have known) about the loss. AFCA can extend these in limited special circumstances, but don't rely on it — lodge promptly. Source: AFCA process.
What AFCA can and can't do
AFCA can review whether the insurer's decision was fair and reasonable, order it to pay a claim, correct a valuation, and award interest plus compensation for non-financial loss (stress and inconvenience). What it generally won't do is determine who was legally at fault for an accident — that's a court's job. So a pure "I disagree with the fault finding" complaint is reviewed on whether the process was fair, not re-litigated as a liability case.
How the process runs
In broad terms: you lodge, AFCA refers it back to the insurer for one more chance to resolve, then a case manager works through it — often via negotiation or conciliation — and, if it's still not resolved, AFCA issues a preliminary assessment and ultimately a binding determination if you accept it. Simple cases can move quickly; complex ones (fraud, big valuation fights) can take many months. There's no fixed end date, so be patient and keep your file organised.
The kit includes an AFCA lodgement summary you complete yourself — a one-page structure that organises your complaint the way AFCA's online form asks for it: the parties and policy/claim numbers, a tight chronology of what happened, the denial reason and why you say it's wrong, the evidence you're relying on, and the outcome you're seeking. It's a general organising tool to make lodging easier, not legal advice or a document we lodge for you.
7. Step 4 — Tribunal or court
For most people, IDR and AFCA are enough, and AFCA is free where court is not. But if you've exhausted those and still disagree — or your matter falls outside AFCA's scope — a state tribunal or court is the backstop. Because AFCA determinations don't bind you, accepting an unfavourable outcome is never forced; you keep your court rights.
Depending on your state and the amount involved, that might be a civil and administrative tribunal (such as VCAT in Victoria or NCAT in NSW) or the Magistrates'/Local Court. This is the point where the cost-benefit changes and many people choose to get advice. Talk to one of the free services in Section 11 before going down this road — they can tell you whether it's worth it.
8. Non-disclosure & misrepresentation explained
"You didn't disclose something" is one of the most common denial reasons — and one of the most misunderstood. The law tilts further toward the consumer than most people realise.
The duty changed in 2021
For consumer car policies taken out or renewed from 5 October 2021, you no longer have a broad "duty of disclosure." Instead you have a narrower duty to take reasonable care not to make a misrepresentation. The practical effect: the insurer can't just say you failed to volunteer something — they generally have to show you were actually asked, and that you failed to take reasonable care in answering.
The insurer carries the burden
Even where non-disclosure or misrepresentation is established, the insurer can't automatically walk away. Under the Insurance Contracts Act, to reduce or refuse a claim it generally has to show it was prejudiced — that it would have done something different (charged more, added a condition, or declined) had it known. And the contract runs both ways: insurers and consumers both owe a duty of utmost good faith.
Worked examples
- The second-hand modified car. You bought the car used and genuinely didn't know it had been modified. According to Littles Lawyers, if you genuinely didn't know and the insurer would still have covered you (perhaps at a higher premium), they generally can't reject the claim outright — they may only be able to charge the difference.
- The bushfire write-off. The car had an undeclared modification, but it was destroyed in a bushfire that had nothing to do with the mod. As reported by Insurance News, the irrelevance of the undisclosed item to the actual loss limits how much the insurer can refuse.
- The unrecorded disclosure. You say you told them during the application call, but they have no record of it. Ask for the recorded application Q&As and underwriting guidelines — AFCA has overturned denials where the insurer's own process failed to capture a disclosure you actually made.
9. Disputing a total-loss / write-off valuation
Sometimes the claim is accepted but the payout is the problem: the insurer writes the car off and offers a figure that's well below what the car was worth. This is a genuine dispute, and AFCA hears valuation cases regularly.
Agreed value vs market value
- Agreed value — a figure locked in at policy time. It typically depreciates a little each renewal, which is why this year's agreed value can be lower than last year's. If you didn't raise it at renewal, it's hard to dispute at claim time.
- Market value — what the car was worth just before the loss. This is where most valuation disputes happen, and it's a question of evidence, which means you can fight it.
Build a counter-valuation
To challenge a low market-value offer, assemble comparable sales: current listings and recent sold prices for the same make, model, year, trim, condition and kilometres, ideally in your state. Tools like RedBook and Glass's Guide give a baseline, but real comparable listings are the most persuasive. If you can show a cluster of genuinely comparable cars selling for more than the insurer's offer, you have a real case — AFCA has overturned insurer pre-accident valuations on exactly this kind of evidence. See AFCA's approach to motor vehicle valuations.
Check the payout maths
A total-loss payout is usually the value minus deductions: your excess, and sometimes the remaining premium for the year (insurers often deduct the unpaid balance because the policy ends when the car is written off). Make sure the deductions are correct and that the starting value is right before you accept.
10. Scenario quick-answers
"I disagree with the at-fault decision."
You can dispute it through IDR and AFCA, but remember AFCA reviews whether the insurer's process was fair and reasonable — it doesn't decide legal liability. If you want a binding fault finding, that's a court. Worth raising if the assessment ignored evidence (dashcam, witnesses); manage expectations if it's purely your word against theirs.
"They denied me for drink-driving — but I was only just over the limit."
This is more nuanced than most people assume. A reading alone may not be enough: according to Financial Rights Legal Centre, under section 47C of the Insurance Contracts Act regulations an insurer generally can't refuse a claim on a BAC reading alone — it has to show actual impairment or a real connection to the loss. Where impairment is genuinely proven, though, this remains very hard to win. Don't assume either way — get the free services to look at it.
"I missed a premium payment and then crashed."
This turns on whether the policy had actually been cancelled or was merely overdue. Grace periods and the rules about cancellation notices matter — an insurer generally can't treat you as uninsured without proper notice. Check exactly when (and whether) the policy was cancelled before accepting a denial. See NRMA's guidance on missed payments as one example of how insurers handle this.
"My hail/storm claim was knocked back even though I have comprehensive."
Common reasons include the insurer calling the damage "avoidable" (you ignored a weather warning), an embargo or waiting period, pre-existing or undisclosed damage, or the damage being treated as wear-and-tear rather than "sudden and accidental." Each of these is challengeable on the evidence — particularly the wear-and-tear angle. See Allianz's hail-damage explainer for how insurers frame these.
"My claim is 'under review' / 'under investigation' for fraud."
Being investigated is not the same as being denied. According to Financial Rights Legal Centre, the General Insurance Code of Practice allows investigations to run up to about 4 months (12 for genuinely complex matters), and only a small share of investigated claims are ultimately declined for fraud — most get paid. You can complain about an unreasonable investigation or delay at any time. Cooperate, keep records of every interaction, and don't be pressured into a recorded statement without understanding your rights.
"They're just delaying — there's no decision at all."
Delay is itself a complaint ground. According to Financial Rights Legal Centre, insurers must give an initial response within 10 business days and generally decide a claim within 4 months. If they're dragging, lodge an IDR complaint about the delay, and escalate to AFCA — which can award interest and compensation for the inconvenience.

12. Frequently asked questions
Can I dispute a denied car insurance claim?
Yes. A denial is the insurer's decision, not the final word. You can lodge an internal complaint (IDR), then escalate free to the AFCA ombudsman, and ultimately go to court. You don't need a lawyer and it costs nothing to lodge.
Is AFCA free?
Yes. AFCA is an independent, not-for-profit body funded by its member firms, so the insurer covers the cost of your complaint, not you. Lodging and using the service is free for consumers. (If you choose to hire your own paid representative, that's a separate cost.)
How long does AFCA take?
There's no fixed timeframe. AFCA first gives the insurer a chance to resolve it at referral; simpler cases can move in weeks, while complex disputes (fraud, large valuations) can take many months. Keep your file organised and respond promptly to your case manager.
Do I have to complain to my insurer before going to AFCA?
Yes, in almost all cases. You must first go through the insurer's Internal Dispute Resolution (IDR) process. If they don't respond within the required 30 days, or send a delay notice, you can escalate to AFCA straight away.
Can my insurer refuse to pay because I didn't disclose something?
Not automatically. For consumer policies since October 2021 you only owe a duty to take reasonable care not to misrepresent, and the insurer generally must prove it was prejudiced. If the question was vague, unasked, or unrelated to your loss, the denial is contestable.
Can they deny my whole claim over a modification that had nothing to do with the crash?
Often not entirely. An insurer's remedy is tied to the actual effect of the non-disclosure. Where the undisclosed modification was irrelevant to how the loss happened, refusing the whole claim is frequently disproportionate and challengeable through IDR and AFCA.
My write-off payout seems too low — can I dispute it?
Yes. Market value is a question of evidence. Gather comparable sale listings for the same make, model, year, condition and kilometres. If they show a higher figure than the offer, put that to the insurer and, if needed, AFCA — which has overturned insurer valuations on this kind of evidence.
Can they refuse my claim for drink-driving even if I was only just over the limit?
Not necessarily on the reading alone. Financial Rights Legal Centre notes that under the Insurance Contracts Act regulations an insurer generally can't deny on a BAC figure by itself — it must show real impairment or connection to the loss. Where impairment is proven, though, it's very hard to win.
I missed a premium payment and then had an accident — am I covered?
It depends on whether the policy was actually cancelled or merely overdue. Grace periods and cancellation-notice rules matter — an insurer generally can't treat you as uninsured without proper notice. Check exactly when, and whether, the policy was cancelled before accepting any denial.
What are my chances of winning at AFCA?
There's no published win rate for motor claims, and we won't invent one. What's verifiable: in 2024–25, 73% of complaints AFCA closed before a formal decision (all products) were resolved by agreement or in the consumer's favour. Whether yours succeeds depends entirely on your facts.
