Allianz Australia Insurance Claim Denied? How to Appeal in Australia

Allianz Australia is one of the country's largest general and travel insurers, but claim denials are common across their product lines — travel, home, motor, income protection, and workers compensation. Australian policyholders have strong protections under the Insurance Contracts Act 1984, ASIC's RG 271, and the General Insurance Code of Practice, and the Australian Financial Complaints Authority (AFCA) provides free, binding dispute resolution. This guide covers the most common Allianz denial reasons, your rights under Australian law, and the step-by-step process to appeal.

Why Insurers Deny Allianz Australia Claims

Allianz Australia's denial patterns vary by product line:

• Pre-existing medical condition (travel insurance) — Allianz frequently denies travel claims on the basis that the condition leading to the claim was known or should have been known before the policy was purchased; ASIC's 2019 Report 600 found systemic issues across the industry with overly broad pre-existing condition definitions
• Policy exclusion applied — Allianz cites a specific exclusion such as an unlisted driver, modified vehicle, late notification, or excluded activity
• Not medically necessary — For income protection, life, or health claims, Allianz's reviewing physician disputes the treating doctor's clinical assessment
• Late claim notification — Allianz policies require prompt notification; delays may be cited as grounds for denial, particularly in commercial lines
• Insufficient documentation — Medical reports, receipts, police reports, or supporting evidence do not meet Allianz's requirements
• Workers compensation disputes — Allianz may dispute whether an injury arose from employment, whether it is work-related, or whether treatment is reasonably necessary
• Vehicle modification or excluded driver — Motor claims denied because the vehicle was modified without disclosure or an excluded driver was operating the vehicle

How to Appeal an Allianz Australia Insurance Denial

Step 1: Request Written Reasons from Allianz

Under the Insurance Contracts Act 1984 and the General Insurance Code of Practice, Allianz must provide written reasons for any claim denial. Contact Allianz at 13 1000 or via allianz.com.au and request a formal written explanation if not already provided. Under ASIC's RG 271, Allianz must acknowledge your complaint within 5 business days and respond within 30 calendar days (extendable to 45 days for complex complaints with written notification).

Step 2: Review the PDS and Certificate of Insurance Carefully

Compare Allianz's denial reason to the exact Product Disclosure Statement language. If there is a conflict between the PDS and the Certificate of Insurance, the Certificate may take precedence. Look for ambiguous definitions of "pre-existing condition" or exclusions that were not clearly disclosed at the time of purchase. For travel insurance pre-existing conditions, the definition often requires that the condition was medically diagnosed, treated, or that symptoms were present within a specific look-back period.

Step 3: Obtain Independent Medical Evidence Where Applicable

If the denial involves a medical assessment, note that Allianz's IME doctors are engaged by Allianz and may not produce independent assessments. Obtain reports from your own treating practitioners or an independent specialist. For income protection and workers compensation disputes, independent medical evidence that contradicts Allianz's IME findings is particularly valuable and frequently decisive in AFCA proceedings.

Step 4: File a Formal Internal Complaint with Allianz

Submit a written complaint to Allianz Australia's Complaints team by mail (Allianz Australia, Complaints, GPO Box 9870, Sydney NSW 2001), online through the complaints form on allianz.com.au, or by phone at 13 1000 stating you are making a formal complaint and requesting a reference number. Include your policy number, claim reference, a clear explanation of why the denial is incorrect, all supporting documents, and a request for written response.

Step 5: Escalate to AFCA if Allianz Does Not Resolve Your Dispute

If Allianz's internal process does not resolve your dispute within 30–45 days, lodge your complaint with the Australian Financial Complaints Authority (AFCA) at afca.org.au or by calling 1800 931 678 (free call). AFCA will independently review your case and Allianz's claims file, contact Allianz on your behalf, facilitate a conciliation between you and Allianz, and issue a determination that is binding on Allianz if conciliation fails. AFCA is free for consumers and handles most personal and small business insurance disputes.

Step 6: Follow State-Based Pathways for Workers Compensation

Workers compensation disputes follow state-specific pathways not covered by AFCA. In NSW, disputes go to the Personal Injury Commission (PIC) at pic.nsw.gov.au. In Victoria, disputes fall under WorkSafe Victoria's dispute resolution pathway. Other states have equivalent WorkCover authority processes.
