How to Protect Your Health While Travelling

Quick answer

How to protect your health when you travel: see your doctor six to eight weeks before you go, buy travel insurance that actually covers your conditions, check whether your medicines are legal at your destination, and carry your medical details in a form a foreign clinician can read. Medicare does not cover you overseas, and that surprises people at the worst possible moment.

Most travel health advice is a list of vaccinations. The things that actually derail trips are duller: an insurance policy that excluded a pre-existing condition, a medication confiscated at a border, or a hospital in another country with no way to find out what you take.

1. Research the destination properly

Health risks and required vaccinations for each country, including places you are only transiting.
The standard of local medical care, and where the nearest decent hospital is to where you are staying.
Whether Australia has a reciprocal health care agreement with that country. Australia has agreements with a limited number of countries, they cover only some care, and they are not a substitute for insurance — check the current list with Services Australia.

2. Get insurance that covers you, not just a policy

Medicare does not cover you overseas. Without insurance you are personally liable for treatment and, in a serious case, for medical evacuation — which can run into six figures.

Read the policy for these specifically

Pre-existing conditions. Most policies exclude them unless declared and accepted. Declare everything — an undeclared condition can void a claim entirely, including for something unrelated.
Medical evacuation and repatriation, which is the expensive part.
Activities — diving, skiing, motorbikes and trekking above certain altitudes are commonly excluded.
Pregnancy, which many policies limit by gestation.
Age limits and any cap on cover for older travellers.
The emergency assistance number — save it offline, not just in your email.

Smartraveller’s guidance on travel insurance is blunt about this, and worth reading before you compare prices.

3. See your doctor early

Aim for six to eight weeks before departure. Some vaccines need multiple doses or time to become effective, and rushing that is how people travel unprotected.

Vaccinations for your destination, and any boosters you are due anyway.
Enough medication for the whole trip plus a buffer, in case of delays.
A letter from your doctor listing your conditions and medications, generic names included.
Advice on managing your condition across time zones — particularly important for insulin.
Malaria prophylaxis or altitude advice, if relevant.

4. Check your medicines are legal where you are going

This is the one people do not think about

Medicines that are ordinary prescriptions in Australia are restricted or illegal in some countries — including common painkillers, ADHD medications, and some cold and sleep preparations. Penalties can be severe. Check the rules for every country you enter, including transit stops, using Smartraveller’s guidance on medications and the destination’s embassy.

Keep medicines in original labelled packaging.
Carry them in hand luggage, with a spare supply packed separately in case a bag is lost.
Bring the doctor’s letter and a copy of your prescriptions.
Do not buy replacements from unregulated sources overseas — counterfeit medicines are a real problem.

5. Make your medical details readable abroad

A hospital in another country has no access to your Australian records, may not speak fluent English, and cannot ring your GP at 3am local time. What it can work with is something you carry.

Conditions and allergies with the reaction, not just the trigger.
Medications by generic name — brand names differ between countries, and a generic name is far more likely to be understood.
Blood type, if you know it.
Devices and implants, including where they sit — see what counts as medical implants or devices.
Emergency contacts in international format, with the country code, so they can actually be dialled — see how to set up your emergency contacts.

Something worn matters more overseas than at home, because nobody around you knows anything about you. See what to put on a medical wristband and what to include in medical records.

A hospital overseas cannot look you up.

Staying well on the way

Risk	What helps
Blood clots on long flights	Move regularly, stay hydrated, and ask your doctor beforehand if you have clot risk factors
Dehydration	Water rather than alcohol and coffee, especially on long sectors
Time-zone medication timing	Work the schedule out with your pharmacist before you fly
Jet lag	Shift to local time immediately, and get daylight on arrival

While you are away

Water and food — where tap water is not safe, that includes ice and salad rinsed in it.
Insect-borne disease — repellent and covering up matter as much as any tablet.
Sun — closer to the equator and at altitude, burn time is shorter than you are used to.
Road safety, which is statistically the biggest risk to travellers in many countries.
Know how to call for help locally. The emergency number is not 000 elsewhere — look it up on arrival.

If something does go wrong, contact your insurer’s emergency line early rather than paying up front and hoping to claim later, and keep every receipt and report.

If you have a chronic condition

Travelling with a long-term condition is entirely normal — it just needs the planning done rather than assumed.

Get your condition declared and accepted in writing on the policy.
Plan for refrigerated medication and for power for any device.
Find out where you would go locally for a flare-up, before it happens.
Take more supplies than the itinerary needs, and split them between bags.

FAQs

How do I protect my health while travelling?

See your doctor six to eight weeks before you go, buy travel insurance that covers your declared conditions, check whether your medicines are legal at every country you enter, and carry your medical details in a form a foreign clinician can read. Medicare does not cover you overseas, so insurance is not optional.

Does Medicare cover me overseas?

No. Medicare does not cover treatment overseas, so without travel insurance you are personally liable for medical costs and for evacuation, which can run into six figures. Australia has reciprocal health care agreements with a limited number of countries, but those cover only some care and are not a substitute for insurance.

Will travel insurance cover my pre-existing condition?

Only if you declare it and the insurer accepts it, usually in writing and sometimes for an extra premium. Most policies exclude undeclared pre-existing conditions, and an undeclared condition can void a claim entirely, including for something unrelated. Declare everything, even conditions that feel minor or historical.

Can I take my prescription medicines overseas?

Not always. Medicines that are ordinary prescriptions in Australia are restricted or illegal in some countries, including common painkillers, ADHD medications and some cold and sleep preparations, and penalties can be severe. Check the rules for every country you enter, including transit stops, using Smartraveller and the destination's embassy.

How should I pack medication for a trip?

Keep it in original labelled packaging, carry it in hand luggage rather than checked baggage, and split a spare supply into a separate bag in case one is lost. Bring a letter from your doctor listing your conditions and medications with generic names, plus copies of your prescriptions. Take more than the itinerary requires in case of delays.

Why record medications by generic name when travelling?

Because brand names differ between countries, so a brand a pharmacist knows in Australia may mean nothing overseas. The generic name is far more likely to be recognised, which matters when you need a replacement supply or when a clinician is deciding what is safe to give you.

How far ahead should I see my doctor before travelling?

Six to eight weeks before departure. Some vaccines require multiple doses or need time to become effective, so leaving it later means travelling without full protection. It also gives time to arrange enough medication, a doctor's letter, and advice on managing your condition across time zones.
