The easiest way to exchange your AUD while you’re away is to get a multi-currency account which you can top up in AUD digitally, with a card or bank transfer. You can then switch the AUD balance to the currency you need using the provider’s app. Choose a provider like Wise, and you can get a linked debit card, so you can add money in AUD, and then withdraw in the currency you need using an ATM wherever you are in the world.
