15 Things people forget before travelling overseas (And why they matter)

You can spend months planning a trip and researching things to do. Yet it's often the smallest details that get forgotten, and they're usually the ones that cause the most frustration once you're overseas.

Before you zip up your suitcase and head to the airport, it's worth taking a few minutes to double-check the details that are easiest to overlook. Here are some of the things travellers most often forget — and why they're worth checking off your list.

1. Checking your passport expiry date

Most travellers remember to pack their passport, but many forget to check whether it's valid for long enough to meet entry requirements.

While your passport may not expire until after your holiday, that doesn't necessarily mean you can travel. Many countries require passports to be valid for at least six months beyond your planned departure date, and some have additional requirements regarding blank pages or passport condition.

It's also worth checking the rules for any countries you're transiting through, as some destinations apply entry requirements even for short stopovers.

2. Saving your Travel Insurance documents

Many people arrange Travel Insurance and then promptly forget about it until something goes wrong.

If you experience a medical emergency, travel disruption or lost belongings overseas, having immediate access to your policy details can make a stressful situation much easier to manage.

Before you travel, save:

• Your policy number
• Emergency assistance contact details
• Claims information
• A copy of your Certificate of Insurance

Store copies digitally on your phone and in cloud storage, and consider keeping a printed copy in your luggage.

You should consider whether a product is suitable for your needs. Please read our Product Disclosure Statement (PDS) and Target Market Determination (TMD) before deciding to purchase. 

3. Getting a letter for prescription medication

Travellers are usually careful to pack their medication, but many don't realise that some countries have strict rules about what medicines can be brought across their borders.

Even common prescription medications may require supporting documentation.

Before you travel, ask your doctor for a letter that outlines:

• Your medical condition
• The medication you're carrying
• Dosage requirements
• Any medical devices you need to bring

This documentation can help avoid delays at customs and may also make it easier to obtain replacement medication if yours is lost or damaged during your trip.

It's also a good idea to keep medication in its original packaging whenever possible.

4. Packing the correct power adapter

Many travellers assume their existing adapter will work everywhere, only to discover that different countries use different plug types and voltages.

Before you travel, research the power outlets used at your destination and check whether you'll need:

• A country-specific adapter
• A universal adapter
• A voltage converter

Don't forget chargers for phones, tablets, cameras, smartwatches and any other devices you plan to use.

5. Telling your bank you're travelling

Using your card overseas without notifying your bank can sometimes trigger fraud prevention systems. From your bank's perspective, sudden transactions from another country may appear suspicious, resulting in temporarily frozen accounts or declined payments.

Notifying your bank before you travel can help minimise the risk of disruption. While you're speaking with your bank, it's also worth asking about:

• International transaction fees
• ATM withdrawal charges
• Travel-friendly card options
• Emergency card replacement services

Understanding these costs in advance can help you avoid unexpected expenses while you're away.

6. Downloading offline maps

Many travellers rely heavily on mobile data for navigation, only to discover they don't have reliable internet access when they arrive.

Downloading maps before you leave allows you to:

• Navigate unfamiliar destinations
• Find accommodation
• Locate public transport
• Access directions without mobile data

Offline maps can be particularly useful if you're travelling through rural areas or multiple countries.

7. Bringing local currency for arrival

Although card payments are widely accepted in many destinations, having some local currency available when you land can still be incredibly useful.

You may need cash for:

• Airport transfers
• Taxis
• Public transport
• Tips
• Small purchases

After a long flight, the last thing most travellers want is to search for an ATM or discover that card payments aren't accepted. Having a modest amount of local currency available can make your arrival significantly smoother.

8. Making copies of important documents

Losing important documents overseas can be stressful, but having copies can make replacement and recovery much easier.

Consider creating copies of:

• Passports
• Visas
• Travel Insurance documents
• Flight itineraries
• Hotel bookings
• Driver's licences

Store physical copies separately from the originals and save digital copies securely online. If your passport is lost or stolen, having these documents available can significantly speed up the replacement process.

9. Packing a portable power bank

Your phone is likely to be one of the most important items you carry while travelling. A portable power bank provides valuable backup during:

• Long-haul flights
• Airport delays
• Day trips
• Extended sightseeing

It's a simple item that's easy to overlook but often proves invaluable.

10. Checking international roaming costs

Many travellers don't think about mobile phone charges until they return home and receive an unexpectedly large bill. International roaming costs can vary significantly between destinations and providers.

Before you travel, compare:

• International roaming packages
• Local SIM cards
• eSIM options
• Wi-Fi-only solutions

Researching your options ahead of time can help you stay connected while avoiding unnecessary costs.

11. Packing basic medications

When travelling overseas, finding familiar brands and medications isn't always straightforward. Language barriers, different product names and varying pharmacy regulations can make replacing basic items more difficult than expected.

A small travel health kit could include:

• Pain relief medication
• Motion sickness tablets
• Antiseptic wipes
• Rehydration sachets
• Anti-diarrhoeal medication
• Adhesive bandages

Having these essentials available can save time and discomfort if minor health issues arise during your trip.

12. Updating emergency contact information

Most people store important contact details exclusively on their phone. However, if your device is lost, stolen or damaged while travelling, accessing those contacts may become difficult.

Before you leave, ensure trusted family members or friends have:

• Your itinerary
• Accommodation details
• Emergency contact information
• Copies of key documents if appropriate

It can also be useful to carry a printed list of important phone numbers in case technology fails when you need it most.

13. Checking vaccination requirements

Health requirements vary significantly between destinations. Some countries require proof of specific vaccinations before entry, while others strongly recommend certain immunisations based on local health risks.

Booking an appointment with your doctor or a travel clinic several weeks before departure allows sufficient time to prepare properly.

14. Setting up backup access to online accounts

Many online services now use two-factor authentication for security. While this helps protect your accounts, it can create problems if your phone is lost or stolen while travelling.

Before you leave, consider:

• Saving backup authentication codes
• Setting up alternative recovery methods
• Ensuring trusted devices remain accessible
• Updating recovery email addresses

These simple steps can help you regain access to important accounts if your primary device becomes unavailable.

15. Reviewing your Travel Insurance cover

Before you travel, take time to review your cover and ensure it suits your plans. For example, consider whether your policy includes:

• Overseas medical expenses
• Trip cancellation cover
• Baggage protection
• Cruise cover, if relevant
• Adventure activities you plan to participate in

If you have pre-existing medical conditions, it's important to disclose them when obtaining a quote so you can understand what cover may be available.

Taking a few minutes to review your policy before departure can help you travel with greater confidence, knowing you've arranged cover that meets your needs.

A few minutes of preparation can save a lot of stress later

When preparing for a trip overseas, it's usually not the obvious things that catch people out. So it’s worth taking the time to work through these commonly overlooked travel essentials before you leave.

And while you're ticking off your travel to-do list, don't forget to arrange Travel Insurance that suits your needs. A little preparation now can help you focus on enjoying your travels with confidence.
