Pre-Existing Conditions
and Travel Insurance

Pre-existing medical conditions are the most disputed area of Australian travel insurance. Understanding what counts as pre-existing, when to declare, and what happens if you don’t can be the difference between a paid claim and a voided one.

1. What Is a Pre-Existing Condition?

Definition varies by insurer but the common standard is: any medical condition for which you received medical advice, a diagnosis, treatment, medication, or experienced symptoms during a specified “look-back period” prior to purchasing the policy.

Look-Back Periods

Look-back periods vary by condition type and insurer. The following reflects common market practice — always check the exact period in your insurer’s PDS, not a general rule:

  • Minor conditions (e.g. minor infections, sprains): often 3–6 months
  • Ongoing / managed conditions (e.g. controlled diabetes, hypertension): 12–24 months
  • Serious conditions (e.g. cardiac events, cancer): up to 3–5 years
  • Always check: the look-back period is defined in your insurer’s PDS, not by a general rule
Important: Symptoms Count — Even Without a Formal Diagnosis

A condition does not need to be diagnosed to count as pre-existing. If you had symptoms you were aware of — even if not yet formally diagnosed — during the look-back period, it may count as pre-existing under many policies. The test is not “did a doctor confirm it?” but “did you know, or should you reasonably have known, something was wrong?”

2. The 14–21 Day Rule (Time-Sensitive Benefits)

Most Australian travel insurers offer enhanced benefits — including pre-existing condition waivers — if you purchase within 14–21 days of making your first trip payment (flight deposit, hotel booking, tour payment).

What the Early Purchase Window Unlocks

  • ✓
    Pre-existing condition waiver: if the condition meets stability criteria, it may be covered under standard terms at no extra premium
  • ✓
    Cancel For Any Reason (CFAR) add-on: typically only available during the early purchase window
  • ✓
    Broader trip cancellation coverage: some insurers expand the list of covered cancellation reasons for early purchasers
Stability Criteria — Common Requirements for Waiver Eligibility
  • No change in medication, dosage, or type in a specified period (often 60–180 days)
  • No new symptoms, hospitalisation, or specialist referrals in the look-back period
  • No elective surgery scheduled

If the condition is not stable by these criteria, coverage may still be available via a paid health assessment. Stability requirements vary by insurer — check your PDS for the exact definition.

3. How to Declare a Pre-Existing Condition

The declaration process is more straightforward than many travellers expect. Follow these steps before purchasing:

  1. 1
    Collect your medical history relevant to the look-back period Gather current medications and dosages, dates of specialist visits, any diagnoses, hospitalisation dates, and key test results (e.g. HbA1c readings, blood pressure measurements).
  2. 2
    Complete the insurer’s online health assessment (or telephone assessment for complex conditions) Most insurers offer an online questionnaire. For complex medical histories, call the insurer’s travel line to arrange a telephone assessment with a trained assessor.
  3. 3
    Receive an assessment outcome The insurer will provide one of four outcomes: (a) covered under standard terms; (b) covered with an additional premium; (c) excluded from coverage — the condition is excluded but the remainder of the policy remains valid; (d) policy declined.
  4. 4
    If declined or excluded: try another insurer Different insurers assess conditions differently based on their own underwriting criteria. A condition excluded by one insurer may be covered — possibly with a loading — by another. Don’t stop at the first refusal.
  5. 5
    If still unable to get coverage: specialist travel insurers Specialist travel insurers such as AllClear and Good2Go cater specifically to higher-risk travellers with complex medical histories and are worth approaching if standard insurers decline.
Declare Everything That Could Possibly Be Relevant

Insurers are required to ask clear, unambiguous questions. If a question was ambiguous and you gave a reasonable answer, AFCA may rule in your favour in a dispute. But deliberate non-disclosure is very hard to defend and can result in the entire policy being voided — not just the claim relating to the undisclosed condition.

4. Common Conditions and Typical Outcomes

Assessment outcomes vary by insurer and individual circumstances. The following reflects typical market outcomes based on publicly available PDS guidance and AFCA determination data. Always complete an individual assessment — do not assume coverage or exclusion without going through the process.

Condition Typical Outcome Notes
Type 2 diabetes (controlled) Assessment required Small additional premium common. HbA1c and medication history assessed. Must be stable.
Hypertension (controlled) Assessment required Blood pressure readings and medication stability assessed. Usually coverable with loading.
Asthma (mild, no recent hospitalisation) Often auto-covered Severe asthma or recent hospital admission may require full assessment and additional premium.
Anxiety / depression (stable, in remission) Usually assessable Active episodes or recent medication changes may be excluded. Additional premium common.
Previous cancer (treatment complete) Assessable — varies Outcome depends on time since treatment and recurrence risk. Many insurers cover cancer in remission after 2–5 years.
Recent joint replacement Often covered General travel coverage typically available. Specific activities (skiing, hiking) may be excluded post-surgery.
Cardiac event (heart attack, stent) in past 12 months High risk — complex Additional premium or exclusion common. Specialist insurers may cover. Timing of the event matters significantly.

5. If Your Claim Is Denied — Pre-Existing Condition Grounds

A claim denial on pre-existing condition grounds is not necessarily final. Australian law gives you clear, enforceable rights to challenge it.

Your Rights: Step by Step

1
Request the full claim file and denial reason in writing
The insurer must provide written reasons for the denial, including which PDS clause they are relying on and how they determined the condition was pre-existing. Request the complete claim file — this includes any medical assessments the insurer commissioned internally.
2
Lodge an Internal Dispute Resolution (IDR) complaint
Lodge a formal IDR complaint with the insurer’s complaints team (not the claims team). The insurer must respond within 45 days under AFCA benchmark standards. Clearly state why you believe the denial was incorrect, referencing the PDS language and your original disclosure responses.
Overturned at IDR
Insurer reverses the denial or offers a settlement. Review any settlement offer carefully before accepting.
Upheld → Step 3
IDR upholds the denial. You may now escalate to AFCA at no cost.
3
Lodge with AFCA — free, binding on the insurer
Visit afca.org.au and lodge a complaint online. You have up to 2 years from the IDR decision to lodge. The process is free, conducted in writing, and AFCA’s determination is binding on the insurer.

What AFCA Examines in Pre-Existing Condition Disputes

If questions were unclear or the condition was unrelated to the claim, AFCA may overturn the denial. The four key factors AFCA considers:

❓
Were the insurer’s questions clear?
Were the health declaration questions clear and unambiguous? If not, AFCA may rule that your answer was reasonable even if it was technically incomplete.
💬
Was the answer reasonable?
Did the traveller give a reasonable answer based on the question asked? Ambiguous questions that led to innocent omissions are treated differently from deliberate concealment.
🔗
Was the condition related to the claim?
Was the undisclosed condition actually related to the claim? If a claim is for a broken arm and the undisclosed condition is diabetes, AFCA may find the non-disclosure was not material to that specific claim.
🧠
Was non-disclosure innocent or deliberate?
Innocent omissions and deliberate concealment are treated very differently by AFCA. Innocent mistakes may still result in a paid or partially paid claim; deliberate concealment is very hard to defend.

6. Annual Multi-Trip Policies

For frequent travellers, annual multi-trip policies offer a more efficient approach — but pre-existing condition management works differently to single-trip policies.

Under an annual multi-trip policy, you declare conditions once at purchase for the entire policy year. The assessment outcome applies to all trips taken under that policy during the year, avoiding the need to re-declare for each individual trip.

However: if your medical condition changes during the year — new medication, a hospitalisation, a new diagnosis, or a change in stability status — you must notify your insurer. Coverage may need to be reassessed before subsequent trips. Failing to notify the insurer of a material change mid-year carries the same non-disclosure risk as failing to declare initially.

Frequently Asked Questions

A pre-existing condition is generally any medical condition for which you received advice, a diagnosis, treatment, medication, or experienced symptoms during a look-back period before purchasing your policy. The look-back period varies by insurer and condition — typically 3–6 months for minor conditions and up to 3–5 years for serious conditions like cardiac events or cancer. The definition is in your insurer’s PDS. A condition does not need to be formally diagnosed to count — known symptoms may be sufficient.
Yes, in most cases. Most Australian travel insurers offer a health assessment process that allows travellers to declare conditions and receive a coverage decision. Common conditions like controlled type 2 diabetes, hypertension, and mild asthma are regularly assessed and covered, often with a small additional premium. If standard insurers decline, specialist travel insurers such as AllClear and Good2Go cater specifically to higher-risk travellers.
If a claim arises that is related to an undisclosed pre-existing condition, the insurer may deny the claim and may void the entire policy — not just the portion relating to the condition. Non-disclosure of a material condition is the most common cause of travel insurance claim disputes at AFCA. Always declare anything that could possibly be relevant. If you’re unsure whether something counts, declare it anyway — the insurer will make the determination.
Controlled type 2 diabetes is commonly covered by Australian travel insurance after a health assessment. The insurer will typically ask about your HbA1c levels, current medications, and whether your condition has been stable in the look-back period. An additional premium is common. Unstable or recently diagnosed diabetes, or type 1 diabetes with complications, may face more restrictive terms. Always complete the health assessment — do not assume you are covered or not covered without going through the process.
Most Australian travel insurers offer time-sensitive benefits — including pre-existing condition waivers — if you purchase within 14–21 days of making your first trip payment. Purchasing early may allow a stable pre-existing condition to be covered under standard terms at no extra premium, compared to purchasing later when a formal assessment and additional premium would typically apply. The exact window varies by insurer — check your PDS. This is one of the strongest practical arguments for buying travel insurance at the time of booking, not close to departure.
❖ Bottom Line

Declaration is always better than non-disclosure. And if you’ve been denied, you have options.

Most Australians with pre-existing conditions can get travel insurance — the process is more accessible than many people assume. The risk is not in having a condition; it’s in failing to declare one. An additional premium is always cheaper than an uninsured overseas medical bill.

If your claim has been denied on pre-existing condition grounds, do not accept the first decision as final. AFCA regularly finds in favour of consumers where insurers’ questions were ambiguous or the undisclosed condition was unrelated to the actual claim. The IDR and AFCA processes are free, and a significant proportion of travel insurance disputes result in outcomes favourable to the consumer.
