Nobody wants to be the person standing at arrivals trying to figure out how to pay for food, or Googling "where to buy a SIM card" in a foreign country – which, if you think about it, is a fairly circular problem to have with no internet.

This list of international travel essentials covers what most travellers are likely to need abroad, whether you're planning your first overseas trip or just want a quick reminder of what to pack for international travel.

Putting it together meant going back and forth on almost every item, separating what was truly essential from what I'd simply gotten used to packing out of habit.

How I decided what counts as an essential

Different types of travellers pack differently. A backpacker, business traveller, digital nomad, and resort vacationer can all take successful trips with very different packing lists.

That's why this list sticks to the common ground – the things nearly every trip abroad needs, regardless of travel style – and sorts them into tiers based on how important they are to have before you leave.

Before anything made the essentials section, it had to pass at least one of these tests:

You can't realistically take the trip without it.
It's difficult or impossible to replace once you're abroad.
It's significantly easier, cheaper, or less stressful to sort out before leaving home.

Some items pass that test for almost everyone. Others are useful – sometimes very useful – but depend on your travel style. Those go into the highly recommended category instead.

A checklist of international travel essentials

The things you can't really travel without

Passport – and check the expiry date. Many countries require at least six months' validity beyond your travel dates.
Visa (if required) – confirm requirements for your specific nationality and destination before you fly.
Vaccination or health certificates (if required) – non-negotiable for the destinations that ask for them at the border.
International driving permit – only if you're planning to rent a car or ride a motorbike abroad.
Copies of your onward travel proof and emergency contacts – printed or saved offline. Immigration sometimes asks for proof of onward travel.
Phone charger – easy to forget
Prescription medication, in its original packaging, plus a copy of the prescription.
Local currency cash – even in destinations that lean heavily on electronic payments, it's useful to have some on hand for situations where cards or apps don't work.
Credit card – make sure overseas usage is enabled before you fly.
Prepaid travel card (Wise, BigPay, Touch ‘n Go and similar) – often better exchange rates than a standard card, and you're never exposing your main bank account.

Universal travel adapter – only essential if your destination uses a different plug type than home, but when it does, this is the one that actually matters. If you're only visiting one region, a cheaper single-region adapter may be enough. Frequent travellers tend to prefer an all-in-one version that covers multiple countries.

Toothbrush – toothpaste is shareable in a pinch. A toothbrush isn't.

A note on clothing: it's obviously essential, but it doesn't reduce neatly to a checklist item. How much you pack depends on trip length, laundry access, climate, and the cultural norms of where you're headed. Pack for the weather and for the culture, and let the quantity flex around your specific trip.

The things that make international travel easier

Travel insurance – covers what’s difficult to deal with abroad: medical emergencies, cancellations, lost luggage.
Debit card – fine as a backup, but lead with your credit or prepaid card as the primary.
Photocopy (or photo) of your passport, stored separately from the original – speeds up replacement significantly if the original is lost or stolen.
Pen – landing cards and customs forms still ask for one in a lot of countries. There's sometimes a shared pen at the form stand, but when a full planeload of people lands at once, you're waiting on it. Bringing your own means you're not stuck, and it's an easy one to lend to whoever's next to you.
Plasters and pain relief – Panadol counts here too. For issues too minor to justify hunting down a pharmacy in an unfamiliar place. I've gotten away with not packing my own before, but only because a travel companion happened to have a small supply of medication on hand when I wasn't feeling great.
A multi-purpose balm (Tiger Balm or similar) – my own go-to for sore muscles, insect bites, and headaches on the road. Not something everyone packs, but worth trying if you don't already have a personal cure-all.
Hand sanitiser – useful in places where a wash basin isn't reliably available.
Wipesand tissue packs – for situations sanitiser doesn't cover: sticky hands, tray tables, no toilet paper in sight.
VPN – situational, but useful in countries that restrict access to apps you rely on (banking, messaging, email).
Power bank – between navigation, messaging, booking confirmations, and photos, phone batteries don't always last as long as we'd like.
eSIM or international SIM card – depends entirely on how you travel. If you rely on maps, translation, or messaging on the go, arriving with zero connectivity is a real stress. If you're happy sticking to hotel and public wifi, you may never need one. I personally prefer using an eSIM because of its convenience.

Offline maps, downloaded before you go – same logic as above.
Money belt – international travel often means carrying your passport, cards, and accommodation access all in one place. A money belt is a safer option if you're not carrying a daypack.
Padlock – useful if your luggage, backpack, or hostel locker doesn't have its own locking system.
Toiletry bag – liquids get tossed around in transit more than you'd expect. A dedicated bag contains the damage if something leaks.
Daypack – for carrying the day's essentials separately from your main luggage. I've been loving the Fjällräven Kånken for this.
Plastic bags – not worth buying specially, but reusing what you already have on hand goes a long way: a laundry bag, a rubbish bag for places with no bin nearby, a way to separate wet or dirty items from the rest of your luggage.
Reusable water bottle – saves money, cuts down on single-use plastic, and useful for topping up at filtered stations where available.
