Having a pre-existing medical condition does not mean you cannot get travel insurance, but it does mean you need to be thorough with your disclosure. Australian insurers use medical screening tools to assess your conditions, and many managed illnesses like diabetes, heart disease, and asthma can be covered for an additional premium. Failing to declare a condition can void your entire policy. Review your options below.
Cover-More stands out in the Australian market for its online medical screening tool, which assesses a wide variety of pre-existing conditions and provides an instant outcome. Their comprehensive plans pair strong medical limits with a screening process that covers conditions many other providers decline.
A pre-existing medical condition includes any illness, injury, or health issue that has been diagnosed, treated, investigated, or symptomatic before you buy your travel insurance policy. This covers ongoing conditions you currently manage, stable conditions you consider resolved, and past illnesses that may still influence your health profile. Even something as common as blood pressure medication or a previous knee operation falls within this definition.
Every Australian travel insurer requires full disclosure of all pre-existing conditions at the time of purchase. Most providers use an online medical screening questionnaire where you answer detailed questions about your health, medications, and treatment history. Based on your responses, the insurer will either cover the condition at no extra cost, cover it with a premium loading, exclude that specific condition from the policy, or decline to offer cover altogether.
Non-disclosure is the leading cause of claim denials in Australian travel insurance. ASIC's MoneySmart warns that insurers routinely obtain full medical records from your GP when processing a claim. If an undisclosed condition is found, the insurer can reject the claim and cancel the policy entirely. Even conditions you believe are unrelated to the claim can trigger a denial if they were not declared during the screening process.
The positive news is that a large number of common conditions are insurable. Managed type 2 diabetes, stable heart conditions, controlled asthma, treated high cholesterol, and many other illnesses are regularly covered by Australian providers, sometimes with a modest premium increase and sometimes at no additional charge. Screening outcomes differ between insurers, so a condition declined by one provider may well be accepted by another. See our full Australian travel insurance comparison for provider details.
Knowing the common pitfalls helps you secure appropriate cover and avoid claim disputes.
| Risk | Level | Details | Insurance Impact |
|---|---|---|---|
| Non-disclosure Leading to Claim Rejection | High | Failing to declare a pre-existing condition is the most common reason Australian travel insurance claims are denied. ASIC's MoneySmart identifies non-disclosure as a persistent problem, and the Australian Financial Complaints Authority (AFCA) receives hundreds of related complaints each year. Insurers request your complete GP records during claims assessment, and undisclosed conditions are regularly identified. | Declare every condition, medication, and medical event without exception. If you are uncertain whether something qualifies, declare it regardless. A slightly higher premium is always preferable to having a claim worth tens of thousands of dollars rejected. Cover-More's online screening tool can assess a broad range of conditions and give you an immediate result. |
| Condition Flare-up While Overseas | High | Pre-existing conditions can worsen during travel due to changes in diet, routine, climate, time zones, and physical exertion. Diabetics frequently struggle with blood sugar management across time zones. Heart conditions may be aggravated by heat or altitude. Asthma can be triggered by air pollution in cities like Delhi, Bangkok, or Beijing. Mental health conditions often intensify under the stress of unfamiliar environments. | If your condition was properly declared and accepted during screening, treatment for a flare-up or worsening is normally covered under the medical expenses section. If the condition was excluded, treatment connected to it will not be paid regardless of the circumstances. Know your policy limits before departing. |
| Cancellation Due to Health Deterioration | Moderate | A change in your condition before departure, such as a new test result, medication adjustment, or medical event, may mean your doctor advises against travel. Non-refundable flights, accommodation, and tour bookings can add up to thousands of dollars in lost costs. This risk is particularly relevant for travellers with conditions that fluctuate, like certain cancers or cardiac conditions. | Check your policy's cancellation section carefully. Some policies cover cancellation due to a worsening of a declared and covered condition, while others only cover cancellation for entirely new medical events. This distinction matters greatly if your condition has a history of changing. |
| Medication Complications During Travel | Moderate | Travellers on regular medication face risks including lost or stolen medication, customs confiscation at borders, difficulty obtaining prescriptions overseas, and medications that behave differently in extreme heat or at altitude. Some countries do not stock Australian brand medications, and certain controlled substances are illegal in specific jurisdictions. | Travel insurance generally covers emergency replacement of medication that is lost or stolen. Routine refills and medications you simply forgot to pack are not covered. Verify import restrictions for your medications at your destination through Smartraveller.gov.au. |
| Multiple Conditions Increasing Cost and Complexity | Moderate | Many Australian travellers, particularly those over 50, have more than one pre-existing condition. Each condition adds to the premium loading and complicates the screening assessment. The interaction between conditions, such as diabetes combined with cardiovascular disease, can further elevate the insurer's risk assessment beyond the sum of individual conditions. | Expect higher premiums when declaring multiple conditions. Some providers assess each condition separately while others take a combined view. If one provider's premium loading is very high, another may offer a more competitive outcome. Weigh the total premium cost against the potential medical expenses you could face overseas without cover. |

Pre-existing conditions have a major influence on premium pricing, but the extent depends on several variables.
The nature of your condition and how serious it is carry the greatest weight in the screening outcome. Controlled high blood pressure on stable medication may barely affect your premium. A recent cardiac procedure or ongoing cancer treatment could multiply it several times over. Conditions involving the heart, brain, and lungs generally attract the steepest loadings.
How long your condition has been stable plays a significant role in the assessment. A condition that has remained unchanged for 12 months or longer with no medication adjustments is viewed more favourably than one diagnosed recently. Longer stability periods typically translate to lower premium loadings or broader acceptance.
Declaring multiple pre-existing conditions compounds the premium loading. Each additional condition is evaluated, and the combined loading can be considerable. Where conditions interact, such as diabetes alongside cardiovascular disease, the risk assessment may increase beyond a simple addition of individual loadings.
Your travel destination amplifies the financial impact of pre-existing conditions on your premium. Countries with extremely high healthcare costs like the USA and Canada result in larger loadings because the potential claim value is greater. A heart-related claim in the USA could easily exceed A$250,000.
Age and pre-existing conditions interact to push premiums upward. A 70-year-old with diabetes faces a higher premium than a 40-year-old with the same condition because the age-related risk compounds with the condition risk. Premium jumps are common at age thresholds of 65, 70, 75, and 80.
Insurers look favourably on conditions that are actively and consistently managed. Regular GP visits, adherence to prescribed medications, and up-to-date follow-up tests all demonstrate responsible management. Conditions where treatment has lapsed or been inconsistent are assessed as higher risk.
How Australian travel insurance providers typically handle the most frequently declared conditions. Individual outcomes vary by provider and personal circumstances.
Covers high blood pressure, angina, previous heart attack, heart surgery, atrial fibrillation, stents, and other cardiovascular conditions.
One of the most commonly declared conditions among Australian travellers. Cover outcomes depend heavily on management and complications.
Cover for cancer depends heavily on the type, treatment stage, time since diagnosis, and current health status.
Includes depression, anxiety, bipolar disorder, and other mental health diagnoses. Australian insurers increasingly recognise and assess these conditions.
Asthma is one of the most prevalent pre-existing conditions among Australian travellers and is widely covered when well-managed.
Practical guidance to help you navigate medical screening and secure the right cover.
Disclose every condition, medication, surgery, and medical investigation regardless of how minor you believe it is. This includes well-managed conditions, conditions from years ago, and conditions you no longer take medication for. ASIC's MoneySmart stresses that honest, complete disclosure is the single most important step when buying travel insurance with pre-existing conditions. An honest declaration resulting in a higher premium is always better than a rejected claim.
Medical screening outcomes differ substantially between Australian providers. A condition that one insurer excludes may be fully accepted by a competitor with only a small loading. Run the online screening with at least three providers before settling on a policy or accepting an exclusion. Each insurer uses its own risk model, so results genuinely vary.
Before starting the screening process, collect your current medication list with dosages, recent test results such as HbA1c levels or blood pressure readings, and a brief summary of your medical history. Having this information ready makes the questionnaire faster and your answers more accurate. Your GP can print a summary of your health records.
If a specific condition is excluded from your policy, any claim arising from or connected to that condition will not be paid. You remain covered for all other insured events including unrelated medical emergencies, trip cancellation, luggage loss, and personal liability. An exclusion narrows your cover for that one condition but does not leave you entirely unprotected.
Ask your GP for a letter listing your conditions, all medications with generic names and dosages, and a brief treatment history. This letter helps overseas doctors treat you correctly in an emergency, assists customs officials in understanding your medications, and supports your insurer's claim assessment process.
If your health changes between purchasing your policy and departing, such as a new diagnosis, medication change, or hospital admission, contact your insurer before you leave. Failing to report material health changes can invalidate claims. This is especially important for annual multi-trip policies where your health may shift during the 12-month coverage period.
