The numbers and risks that should shape your trip
A working set of authoritative facts every Australian traveller should know before they pack. Drawn from Smartraveller, the CDC Yellow Book, WHO international travel guidance, NCIRS, and the Australian Immunisation Handbook.
Statistics that change how you prepare
Eight numbers worth remembering. Each is referenced to an authoritative public source at the foot of the page.
30–70%
of travellers get diarrhoea
On a typical 2-week trip, attack rates range from 30% in low-risk destinations to 70% in higher-risk ones, often the single most common travel illness.
CDC Yellow Book
#1
vaccine-preventable illness in travellers
Hepatitis A is the most common vaccine-preventable disease caught by Australian travellers, spread through contaminated food and water in much of Asia, Africa, South America and the Middle East.
Better Health Channel
$280,000
medical evacuation, US to Sydney
A specialised air ambulance home from the United States costs around AUD 280,000. Evacuations from distant or remote locations can exceed 250,000 even without ICU care en route.
Insurance Council of Australia
$1M+
individual US hospital claims
Single claims from US hospitalisations have exceeded one million Australian dollars. A brain aneurysm or severe cardiac event in a US ICU can run thousands of dollars per day.
Insurance Council of Australia
95%
of trip-booked Australians plan insurance
Most Australians who have booked an overseas trip plan to take out insurance. The gap sits in the under-30s, where 1 in 10 actively reject it regardless of destination.
DFAT, Insurance Council of Australia
1,701
Australians hospitalised overseas (2016–17)
In a single reporting year, DFAT helped 1,701 hospitalised Australians overseas, most in Thailand. The five-year trend is up roughly 24%.

reciprocal health-care agreement countries
Australia has reciprocal agreements with 11 countries that cover some emergency care. Medical evacuations are not covered. Medicare doesn’t work overseas.

6–8 weeks
ideal pre-travel consult lead time
Yellow fever is valid 10 days after vaccination, rabies needs 3–4 weeks for the full course, JE 5 weeks. Most travel vaccines need lead time you don’t get in the airport lounge.
Australian Immunisation Handbook
Region-specific facts every traveller should know
Disease patterns vary far more than itinerary brochures suggest. Tap a region for the headline facts.
South-East Asia
- Most Australian DFAT-assisted hospitalisations occur in Thailand.
- Hepatitis A almost universally recommended for travel here.
- Japanese encephalitis risk rises in rural areas during rainy season.
- Rabies is endemic; outdoor and animal-contact itineraries warrant pre-exposure vaccination.
- Dengue, chikungunya and Zika circulate widely, no vaccines for these but mosquito avoidance is critical.
A countdown of what needs to happen, and when
Yellow fever needs 10 days to become valid. Rabies needs three weeks. Hepatitis B needs months for a full course. Here is the working timeline.
6–8 weeks before
Book a travel consult, especially if your itinerary includes rabies, JE, or yellow fever risk.
4 weeks before
Start hepatitis B or combined hepatitis A+B course if needed.
3 weeks before
Begin rabies pre-exposure (3 doses over 3–4 weeks). Confirm prescription antimalarials with GP.
2 weeks before
Hepatitis A (single dose, protective from day 14). Typhoid. Cholera oral.
10 days before
Yellow fever (certificate valid from day 10, now lifelong per WHO).
1 week before
Last opportunity for second dose of JE. Confirm prescription medications, repellent, and basic first aid.
Day of travel
Carry vaccination records (paper and digital), insurance details, AIR statement from myGov.
What an overseas medical emergency actually costs
Medicare doesn’t work overseas. Reciprocal agreements only cover 11 countries and only some care. Insurance is the only realistic backstop.
Hospital admission
Often thousands of AUD per day for routine care; tens of thousands in the US.
Medical evacuation
$25,000 within North America to $250,000+ for distant or remote locations. Air ambulance from US to Sydney: ~$280,000.
ICU stay (US)
A serious cardiac or neurological event in a US ICU can run thousands per day. Total claims exceeding $1M have been recorded.
Medications overseas
PBS doesn’t apply. Common drugs cost many multiples of Australian prices, particularly in the US.
Specialist consults
Variable; many countries demand up-front payment in cash or card before service.
Reciprocal agreements
Cover some emergency care in Belgium, Finland, Italy, Malta, Netherlands, New Zealand, Norway, Republic of Ireland, Slovenia, Sweden and the United Kingdom. Never covers evacuation.
Common traveller misconceptions
Six beliefs that come up at almost every travel consult, paired with what the evidence and authoritative sources actually say.
“I’m staying at a resort, I don’t need vaccinations.”
Food and water exposures occur even in five-star resorts, hepatitis A is the most common vaccine-preventable disease in travellers. Mosquitoes don’t check guest lists.
“I’ve been before and was fine.”
Immunity wanes. Disease patterns change year to year, and one previous trip without illness is not a predictor. Hepatitis A immunity is lifelong after vaccination; the disease isn’t.
“I’ll get vaccines at my destination.”
Most travel vaccines need 1–4 weeks to develop protection. Some (yellow fever, rabies, JE) need a defined lead time before departure.
“Tourist destinations have first-world medicine.”
Medical care quality varies wildly within and between countries. Reciprocal agreements cover 11 countries and don’t cover evacuation. Insurance is the only realistic backstop.
“I’m only away for a few days, what could go wrong?”
DFAT helps 1,700+ hospitalised Australians overseas every year. Short trips don’t prevent traveller’s diarrhoea, vehicle accidents, or infectious exposures.
“Travel insurance is the same as Medicare.”
Medicare doesn’t work overseas. Australian PBS doesn’t apply. Reciprocal agreements give partial cover in 11 countries, never evacuation. Insurance is non-negotiable.
Five things to confirm before you fly
