Travel insurance is one of those things most people buy in a hurry. A few clicks at checkout and it feels sorted. Then something goes wrong overseas and the fine print suddenly matters a great deal. A little time spent reading before you pay can save a lot of stress later.

This guide walks through what a typical policy covers and where the common gaps sit. It draws on guidance published by Smartraveller, the Australian Government travel advice service. Every insurer is different, so treat this as a checklist rather than a verdict on any one policy. Read your own policy wording before you rely on it.

Why medical cover matters most

Medical cover is the main reason to buy travel insurance. Hospital bills overseas can climb fast, and a serious injury may need a flight home with medical staff. Smartraveller notes that most policies have an unlimited sum insured for medical costs. You can usually see this in the benefits table on the quote screen or near the start of the Product Disclosure Statement.

That document is known as the PDS. It sets out what the insurer will and will not pay for. Smartraveller warns that the PDS can include some surprises. Definitions, limits and conditions are where most claims are won or lost.

Your trip planning should start well before the policy, of course. Passports, visas and bookings all come first. Insurance simply sits alongside those other paperwork jobs. It is best sorted early, not on the way to the airport.

Declaring health conditions you already have

This is the area that trips up the most travellers. Some insurers exclude existing medical conditions entirely. Others will cover them for an extra fee, sometimes after a medical assessment. Few policies cover existing mental illnesses such as depression or anxiety.

Minor conditions such as asthma, high blood pressure and diabetes are often covered, according to Smartraveller guidance on what travel insurance covers. This is usually the case if they have been stable for over 12 months. There should also be no surgery planned and no treatment in the past 12 months. Conditions such as heart problems, lung disease or a stroke usually need an assessment first. The same applies if you have had surgery in the last two years.

The simple rule is to declare your condition when you buy the policy if you are unsure. Smartraveller says exactly that. An insurer is unlikely to pay a claim linked to a condition you did not tell them about. Under the Disability Discrimination Act 1992, insurers must assess the actual risk rather than make assumptions, and a letter from your doctor may help.

Anyone planning medical or cosmetic treatment abroad should think carefully about cover too. Many policies are written around unexpected illness, not planned procedures. Our article on the risks of laser surgery overseas looks at that topic in more detail. Ask the insurer directly before you book anything.

Pregnancy, age and family members

Pregnancy cover is often limited. Smartraveller says complications are commonly covered only up to somewhere between 23 and 32 weeks. Some insurers exclude childbirth altogether, and some want a letter confirming you are fit to travel. Check this early if you are expecting.

Older travellers may face higher premiums and stricter conditions. Excess amounts can also be much higher. Smartraveller notes excesses of $2,000 to $3,000 are common for travellers aged 80 and over on illness or injury claims. It pays to compare a few options.

Travel insurance generally covers only the people named on the policy. If you are travelling with children from a previous relationship, make sure each child is listed. Paperwork for children can involve more than insurance, and our piece on child travel consent forms explains what separated parents should think about. Cover for a sick relative back home is also often limited to relatives who live in Australia or New Zealand.

Luggage, valuables and delays

Luggage cover varies widely between policies. Smartraveller found limits ranging from nothing at all up to $25,000. Limits on individual items commonly sit somewhere between about $200 and $6,000. A single item limit can be much lower than the value of a good camera or a ring.

Items left unattended may not be covered. Valuables left in a car or packed in checked luggage are also commonly excluded. If you travel with expensive pieces, read our tips on travelling with valuable jewellery. You may need to list high value items separately or carry them with you.

Delay cover usually starts only after a wait of six to twelve hours. Lost luggage cover often applies only after 12 hours. Insurers also commonly exclude rescheduling caused by the airline or transport provider itself. Keep receipts for anything you have to buy while you wait.

Cancellations and known events

Cancellation cover is where timing really counts. Smartraveller explains that if a risk or event is known before you buy the policy, you will not be covered if it directly affects your trip. That is why buying insurance soon after booking usually gives you better protection. A storm, strike or outbreak that is already in the news may be excluded.

Common exclusions include terrorism, pandemics, military action and a travel provider going broke. Natural disasters are covered more often than not, but policies vary. Many policies cover medical costs during a pandemic but not cancellations caused by one. Only some policies cover the insolvency of an airline or tour company.

Government travel advice can affect your cover as well. For places rated do not travel, most standard policies will not cover you. Smartraveller also notes that government help is extremely limited in those locations. Specialist insurers exist for that kind of travel.

Activities, scooters and alcohol

Adventure holidays need a closer look. Smartraveller advises reading the PDS definitions rather than just looking for a tick next to an activity. Some policies cover canyoning but not abseiling, even though canyoning often involves abseiling. Skiing away from marked runs often needs extra cover.

Riding a motorbike or scooter is another common gap. Some policies require an Australian motorcycle licence even where local law does not. Riding without a helmet can void cover. The same goes for driving a hire car on the wrong licence, and you may need an international driving permit.

Alcohol is the exclusion many people forget. Insurers will not pay for costs that arise from being under the influence of alcohol or drugs. Smartraveller notes that even one or two drinks may give an insurer grounds to refuse a claim if it decides alcohol played a part. Look for the alcohol clause under the general exclusions.

Nerves about the flight itself are a separate issue, and no policy will help with those. If anxiety is holding you back, our article on overcoming a fear of flying has some practical ideas. Once you are in the air, good cover lets you relax a little more. It is one less thing to worry about.

Cruises and trips within Australia

Cruises have their own rules. Ship doctors do not need Medicare provider numbers, so treatment on board generally cannot be claimed through Medicare or private health insurance. This applies even in Australian waters. Domestic travel insurance does not cover medical costs, so a domestic cruise needs a policy that specifically includes it.

Some cruise policies also exclude contagious diseases. Check whether the cover includes being confined to a cabin or missing ports. Read the cruise section of the PDS line by line. The details vary a lot between insurers.

Frequently asked questions

When should I buy travel insurance?

Buy it soon after you book flights or accommodation. Cover for unexpected events generally improves the earlier you buy. Anything already known when you buy the policy is likely to be excluded.

Do I need to declare a minor health condition?

If you are unsure, declare it when you buy the policy. Some minor conditions are covered automatically if they have been stable. Claims linked to conditions you did not declare are often refused.

Does travel insurance cover physiotherapy when I get home?

Generally it does not. Travel insurance covers costs incurred overseas. Ongoing treatment back in Australia usually falls outside the policy.

Am I covered if I have a few drinks?

Not necessarily. Insurers may refuse a claim if they decide alcohol contributed to it. Check the general exclusions in your PDS.
