Insurance Appeal Letter Template Australia: How to Write One That Works

An insurance appeal letter is the single most important document in your claims dispute. In Australia, a well-constructed appeal letter — one that cites your rights under Australian law, references AFCA jurisdiction, and presents your evidence systematically — dramatically increases your chances of success before you even need to escalate to the regulator.

This guide gives you the structure, legal references, and specific language to use in your appeal letter, whether you're disputing a health insurance, life insurance, home insurance, or travel insurance denial.

Your Legal Rights as an Australian Insurance Policyholder

Before writing your letter, understand the regulatory framework that protects you:

Insurance Contracts Act 1984 (Cth): This is the cornerstone legislation governing most general insurance contracts in Australia. Key provisions include:

• Section 13: Duty of utmost good faith — both parties must act in good faith
• Section 14: Insurers cannot rely on a policy provision to reduce liability if it would be harsh or unconscionable
• Section 54: Insurers cannot refuse a claim based on a breach of condition if that breach did not cause or contribute to the loss

Private Health Insurance Act 2007 (Cth): Governs private health insurance in Australia, setting minimum coverage requirements and appeal rights for health fund members.

Australian Financial Complaints Authority (AFCA): Free, independent dispute resolution for financial services complaints including insurance. AFCA can award compensation and direct insurers to pay out claims. Their jurisdiction covers most insurance types except health insurance (which goes to the Private Health Insurance Ombudsman — PHIO).

Duty of Utmost Good Faith: Under Australian insurance law, insurers who deny claims in bad faith — without proper investigation or by ignoring relevant evidence — can be liable for damages beyond the claim value.

The Structure of an Effective Australian Insurance Appeal Letter

Section 1: Your Details and Reference Numbers

Start with a clear header. This seems basic, but it ensures your letter reaches the right department and is linked to your file.

---

[Your Full Name] [Your Address] [Your Email and Phone] [Date]

[Insurer's Complaints Department] [Insurer Name] [Insurer Address]

Re: Formal Appeal — Claim Reference [XXXX] — Policy Number [XXXX]

---

Section 2: Opening Paragraph (State Your Position Clearly)

Keep this direct. Insurers receive thousands of letters — make it immediately clear what you want.

Template:

I am writing to formally appeal the decision dated [date] to deny my claim under Policy No. [XXXX]. I dispute this decision on the grounds that [brief summary of grounds]. I request that you review this decision and pay the claim in full.

---

Section 3: Background and Timeline

Provide a concise, factual chronology:

On [date], I submitted a claim for [description of loss/event]. On [date], I received a rejection letter citing [grounds]. I received no further correspondence until [date if applicable].

---

Section 4: Grounds for Appeal

This is the core of your letter. Address each denial reason separately and specifically. Use the following framework:

4.1 The Insurer Has Misapplied Policy Clause [X]

The rejection letter states that my claim is excluded under Clause [X] of the policy, which reads: "[exact policy language]". However, this clause does not apply in my circumstances because [reason]. The incident/condition in question [does not fall within the definition / occurred outside the exclusion period / was not caused by the excluded factor].

4.2 The Policy Language Is Ambiguous and Must Be Construed in My Favour

To the extent that Clause [X] is ambiguous, I rely on the principle established in Darlington Futures Ltd v Delco Australia Pty Ltd (1986) and the Insurance Contracts Act 1984, s 14, which require ambiguous terms to be interpreted in a manner favourable to the insured. The clause could reasonably be read to cover my circumstances.

4.3 The Insurer Has Not Acted in Utmost Good Faith

The Insurance Contracts Act 1984, s 13 imposes a duty of utmost good faith on both parties. The insurer's decision to deny this claim without [properly investigating / considering the specialist medical evidence / providing adequate reasons] constitutes a breach of this duty.

---

Section 5: Supporting Evidence

List each piece of evidence you are attaching:

In support of this appeal, I attach the following:

1. Specialist medical report from Dr. [Name], dated [date]
2. Hospital discharge summary, dated [date]
3. Photographs of [damage/incident], dated [date]
4. Independent assessment from [expert], dated [date]
5. [Any other relevant documents]

---

Section 6: AFCA Warning (The Critical Paragraph)

This paragraph signals to the insurer that you know your rights and are prepared to escalate. It changes the commercial calculus — AFCA investigations are expensive and time-consuming for insurers.

If this matter is not resolved to my satisfaction within [21/30] days, I will lodge a complaint with the Australian Financial Complaints Authority (AFCA), of which [Insurer Name] is a member. I note that AFCA has jurisdiction to award compensation and may investigate the insurer's claims handling practices more broadly. I strongly prefer to resolve this matter directly and I hope you will treat this appeal with appropriate seriousness.

---

Section 7: Closing and Request

State clearly what you want:

I request that you:

1. Review this appeal and reverse the decision to deny my claim
2. Pay the full amount of my claim: $[amount]
3. Confirm your decision in writing within [21] days

If you require any additional information, please contact me at [email/phone].

Yours sincerely, [Your Full Name]

Key Legal Phrases for Australian Insurance Appeals

These are phrases with specific legal weight in Australia's insurance regulatory environment:

• "Duty of utmost good faith under s 13 Insurance Contracts Act 1984" — signals you know Australian insurance law
• "Contra proferentem construction" — ambiguous language interpreted against the insurer
• "Section 54 defence" — you can use this where the insurer claims you breached a condition that didn't affect the loss
• "AFCA member obligations" — reminds the insurer of their external dispute resolution commitments
• "Independent review under the AFCA rules" — a concrete threat that prompts action
• "Procedural fairness in claims handling" — references ASIC's expectations for good industry conduct

Health Insurance Appeals: Private Health Insurance Ombudsman (PHIO)

If your dispute is with a registered private health insurer (such as Medibank, Bupa, HCF, nib), the Private Health Insurance Ombudsman (PHIO) — not AFCA — handles complaints. Key differences:

• PHIO contact: phio.org.au or 1800 640 695
• Free service for consumers
• Handles benefit disputes, exclusion disputes, hospital coverage disputes
• Can review insurer decisions and make recommendations

Your appeal letter structure is the same, but reference the Private Health Insurance Act 2007 and PHIO rather than AFCA.

---

Timing Your Appeal

Under AFCA's complaint handling rules, insurers must:

• Acknowledge your complaint within 5 business days
• Provide a final response within 30 calendar days for most complaints
• Provide a final response within 45 calendar days for complaints requiring investigation

If you don't receive a satisfactory response within these timeframes, you can take your complaint to AFCA immediately — you don't need to wait for a formal rejection.

Common Mistakes in Australian Insurance Appeal Letters

1. Being too emotional. Your letter should read like a legal document, not a personal plea. Stick to facts, policy clauses, and regulatory references.

2. Not citing the specific clause being disputed. If you don't quote the exact policy language, your letter is vague and easy to dismiss.

3. Sending to the wrong department. Send to the insurer's formal Complaints Department. Internal escalations to your agent or branch often don't trigger formal complaint processes.

4. Not attaching all evidence. Every piece of supporting evidence should be attached to the letter — don't say "evidence to follow."

5. Forgetting the AFCA threat. Insurers pay attention to this. Many claims are resolved at the internal appeal stage precisely because the policyholder signals they will escalate to AFCA.

6. Missing the AFCA filing window. AFCA requires you to file within 2 years of the insurer's final decision. Don't delay.
