How to Safely Use Crypto While Travelling Internationally

Australian crypto investors who travel internationally face a distinct set of security considerations that do not apply to home-based management of digital assets. Public wifi networks, unfamiliar devices, border crossing security checks, and the physical risk of theft create an elevated risk environment for accessing crypto wallets and exchange accounts. With some preparation before departure and consistent habits while travelling, the risks can be managed effectively without sacrificing access to your assets when you need them.

The core principle for crypto security while travelling is minimising your attack surface: carrying only what you need, accessing only what you must, and using only networks and devices you have assessed as reasonably trustworthy. Travellers who apply this principle and plan ahead have a much better experience than those who improvise their crypto access on the road, often using public computers, unsecured wifi, and unfamiliar exchanges out of necessity.

 

Pre-Trip Preparation: What to Do Before You Leave

The most important security decisions are made before you board the plane, not during the trip. Start by deciding how much crypto access you actually need while travelling. For most travellers, access to a small amount of spending crypto (for remittances, purchases, or currency conversion) is all that is needed, and access to long-term savings or investment holdings can be deferred until return.

If you use a hardware wallet for cold storage, consider whether you need to bring it. For trips where you will not need to move significant holdings, leaving the hardware wallet secured at home is the safest option. Bringing a hardware wallet increases the risk of physical theft, potential border customs scrutiny, and the possibility of loss. If you do bring it, store it separately from your PIN and ensure the device itself could not be linked to your identity through any documentation you carry.

Set up a separate travel wallet before departure: a software wallet on your phone containing only the amount of crypto you expect to need during the trip. Transfer that amount from your main holdings to the travel wallet and treat the travel wallet as expendable: if your phone is stolen or the wallet is compromised, you lose only the travel allocation, not your full holdings. Sending crypto to the travel wallet from your main exchange or hardware wallet before departure is straightforward and takes only a few minutes.

 

Device Security for International Travel

The devices you use to access crypto abroad are a key risk factor. Your regular phone or laptop, configured with all your accounts and wallets, is a high-value target if stolen. Travellers to higher-risk destinations, or those who frequently travel for extended periods, sometimes use a dedicated travel phone: a separate device with only the travel wallet and minimal personal information, purchased specifically for travel and factory reset between trips.

Before leaving, ensure your phone and laptop are fully updated: software vulnerabilities in outdated operating systems are exploited by sophisticated attackers, including in some international airports and border zones. Enable full-device encryption (standard on modern iPhones and available on Android and most laptops) to protect stored data if the device is seized or stolen. Disable Bluetooth and NFC when not actively in use to prevent proximity-based attacks, and be aware of shoulder surfing when entering PINs or passwords in public.

For laptop users, a VPN is essential when using any network outside your control. A VPN encrypts all traffic between your device and the internet, preventing the network operator (or anyone monitoring the network) from seeing what sites you access or intercepting unencrypted data. Configure your VPN to start automatically and use a kill switch that blocks all internet traffic if the VPN connection drops, preventing accidental unprotected connections. Choose a reputable VPN provider with a no-logs policy and servers in Australia or other trusted jurisdictions.

 

Public Wifi and Hotel Network Risks

Airport wifi, hotel networks, café hotspots, and other public networks are among the highest-risk environments for crypto activity. These networks may be monitored by the operator, compromised by other users on the same network, or in some cases entirely set up as fake hotspots designed to intercept traffic from travellers. The safe wifi practices for crypto users guide covers the specific threats in detail.

The practical rule for travel is simple: never access exchange accounts, execute transactions, or enter seed phrases or passwords on public wifi without a VPN. Even with a VPN, avoid accessing high-value accounts or conducting large transactions on public networks where possible: defer those actions to your hotel room on a network you have more confidence in (though hotel networks are still semi-public), or use your phone’s mobile data connection (which is significantly more secure than public wifi for most threat models).

Be particularly cautious about phishing on public wifi networks: some network-level attacks intercept HTTP connections and inject content into web pages, including fake login pages for crypto exchanges. Always verify you are on the correct exchange domain (check the full URL carefully, look for HTTPS, and consider using bookmarks rather than typing URLs) before entering any credentials.

 

Border Crossings and Device Security Checks

Some countries permit customs or border security officials to request access to your electronic devices as a condition of entry. The legal requirements vary significantly by country, and the practical enforcement varies further. Australian citizens cannot be compelled to provide device passwords by foreign authorities, but refusal to cooperate may result in device confiscation, detention, or denial of entry, depending on the jurisdiction.

If you are concerned about device security at a specific border crossing, the most effective approach is to travel with minimal sensitive data: no seed phrases, no private keys, no large crypto wallets, and no sensitive financial records on the device. Cloud-based access (logging into exchange accounts rather than storing private keys on the device) is more recoverable after border inspection than self-custody wallets containing private keys.

Consider that customs officials at some borders have the technical capability to image device storage. Any data on the device at the border can potentially be copied and reviewed later. For travellers whose crypto holdings are substantial, treating the border as an adversarial environment for data security, and adjusting what is on the device accordingly, is a proportionate precaution.

 

Emergency Planning: If Something Goes Wrong Abroad

Planning for emergencies before departure is the final component of travel security preparation. The relevant questions are: if your phone is stolen, how do you access funds to cover immediate expenses? If your exchange account is locked, who can you contact? If your travel wallet is drained, what is your fallback?

Ensure you have memorised (or securely stored separately from your devices) the customer service contact details for your primary exchange. Most major Australian exchanges including CoinSpot, Swyftx, and Independent Reserve have account recovery processes, though they typically require identity verification that may be harder to provide from overseas.

Having a small amount of AUD in an international travel debit card (such as a Wise or Revolut card) as a backup to crypto gives you access to funds even if your entire crypto setup is unavailable. A crypto inheritance plan that includes emergency access information for a trusted person back home provides a last resort recovery path. As with all crypto security, the best emergency plan is the one you set up before you need it.
