8 tips for travelling overseas with your credit card

8 tips for travelling overseas with your credit card

Your credit card can be a lifeline while you're abroad, so make sure you set it up and use it correctly to take full advantage of what it has to offer.

Many people will tell you that adventure is at the heart of all travel. And while that may be true, you don’t want managing your finances while you’re overseas to become an adventure in itself.

Using your credit card in the right way while you travel can have a range of advantages, some of which will help save you money as well as keep it secure. Here are some tips to make sure your credit card usage runs smoothly while you’re abroad.

  1. Tell us when you’re travelling overseas and where you’re going – you can do this quickly and easily online with NetBank. If you don’t, we may place a temporary lock on your card if we detect any suspicious overseas transactions.
  2. Make sure we’ve got your current contact details, including a contact number to reach you on while you’re overseas. You can do this in the ‘My Details’ section of NetBank or by calling 13 2221 or dropping into your nearest branch.
  3. Take a look at Lock, block, limit®*, an award-winning innovation exclusive to CommBank. This feature can help you keep tight control of how your card is used – locking and unlocking it from making international payments, blocking it from ATM cash advances and limiting spend per transaction. You can lock and unlock your card with the CommBank app or via NetBank.
  4. If you have one of our Gold, Platinum or Diamond credit cards, included international travel insurance is just one of the perks of your card. You need to activate your international travel insurance via NetBank before you set off to make sure you’re covered^.
  5. Check the expiry date on your credit card to make sure it won’t expire while you’re overseas.
  6. Think about the different ways you may want to spend money while you’re overseas and what will be the right payment mix to suit your trip. Check out this breakdown of fees and charges for our Travel Money Cards, debit MasterCards and credit cards.
  7. You can set up automatic monthly credit card payments if you’re concerned you might forget to make payments while you’re overseas or won’t have regular internet access.
  8. If you’re given the option to pay for something in either Australian dollars or local currency while you’re abroad, it often costs less to pay in the local (foreign) currency. An international transaction fee is payable regardless of the currency chosen, however the merchant may also add on some other charges or use a less favourable exchange rate should you choose to pay in Australian dollars.
