When you use your NAB debit or credit card to make a purchase in a foreign currency or while travelling overseas, your transaction typically incurs an International Transaction Fee. This fee is charged by the bank to cover the costs associated with processing foreign transactions through international payment networks, such as Visa.

The exact amount you pay depends on the specific card product you hold. While many standard NAB cards apply a 3.5% fee to these transactions, other premium products may have different terms. Before you travel or make an online purchase from an international merchant, it is helpful to check your specific card's terms and conditions to understand which fees apply to your spending.

Step-by-Step Guide to Reviewing Your Fees

  1. Log into your NAB Internet Banking or the NAB app.
  2. Locate the 'Accounts' dashboard and select the specific card account you used for the international transaction.
  3. Navigate to your 'Transaction History' to view the specific purchase.
  4. Select the transaction to see the breakdown of the amount charged, which typically shows the merchant price followed by any associated international transaction fee.
  5. Review your monthly statement to see the total sum of fees charged for the billing period if you have made multiple foreign purchases.

Troubleshooting Common Access Issues

1. MFA / Login Issues

  • Cause: You cannot log in to check your transaction history because the SMS security code is not arriving on your device.
  • Simple Fix: Wait two minutes and tap the option to resend the code. Ensure your phone has a stable connection and is not blocking unknown numbers.
  • Fallback Action: Call the NAB internet banking support line to verify your registered mobile number and manually check your statement details.

2. Browser or App Errors

  • Cause: The transaction history page fails to load or shows a blank screen, often due to an outdated app version or a browser cache conflict.
  • Simple Fix: Update the NAB app via your device's app store or clear your mobile browser's cache and cookies.
  • Fallback Action: Access your account through a different device, such as a desktop browser, to see if the information displays correctly.

3. Locked Account / ID / Access Issues

  • Cause: Your card is locked because a foreign transaction triggered a security alert, and now you cannot view your account details online.
  • Simple Fix: Open the 'Cards' section in your app to view any security alerts; you can often verify the transaction and unlock your card directly there.
  • Fallback Action: Contact the fraud and security team using the number on the back of your card to verify your recent activity and restore account access.

Pro-Tip: When paying for goods at a merchant terminal overseas, you may be asked whether you want to pay in the local currency or in Australian Dollars (AUD). Always choose the local currency. If you select AUD, the merchant’s bank chooses the exchange rate, which is frequently less favourable than the rate applied by the Visa network, resulting in higher overall costs.

Frequently Asked Questions

Q: Why is the fee amount different from what I expected?
The international transaction fee is calculated as a percentage of the total transaction value after it has been converted into Australian Dollars (AUD). If you see a discrepancy, it is often because the exchange rate applied by the Visa network fluctuates daily. The fee is applied to the final AUD amount shown on your statement, not the local currency amount. To verify the breakdown, check your transaction history for the specific conversion rate used on that date.

Q: Does the transaction fee apply to online shopping with international retailers?
Yes, the fee applies regardless of whether you are physically overseas or shopping online from home. If you purchase from a website where the merchant processes the transaction in a foreign currency or the business is registered outside of Australia, the international transaction fee will apply. This remains true even if you see prices listed in AUD on the website but the merchant processes the charge internationally. Check the merchant’s payment terms if you are unsure where the transaction will be processed.

Q: Can I use a premium card to avoid this fee?
Some premium NAB card products are designed with different fee structures, meaning they may not charge an international transaction fee for purchase transactions. However, this often excludes cash advances or ATM withdrawals, which may still attract specific charges. Before assuming your card is exempt, log into the NAB website and check the 'Fees and Charges' section specific to your exact card type, as the rules differ between standard, platinum, and signature products.
