If you have ever been asked at an overseas ATM or checkout whether you want to pay in Australian dollars or local currency, you have encountered dynamic currency conversion. Always choose local currency.
What Is Dynamic Currency Conversion?
It sounds like a convenience feature. In practice it is a way for the merchant or ATM operator to make money on your transaction. When you choose to pay in Australian dollars, the exchange rate applied is set by them, not by your bank, and it is rarely competitive.
Your bank or credit card company will almost always offer a better rate when they handle the conversion on their end. Choosing local currency means that responsibility goes back to your bank where the rate is typically more favourable.
Where It Shows Up
Dynamic currency conversion appears at ATMs, hotel checkouts, retail stores, and restaurants. It is common across most international destinations and the prompt is deliberately designed to look like a helpful option for travellers who want to see a familiar currency on the screen.
It is not helpful. It is a margin for the merchant or company providing the terminal.
The Simple Rule
Always choose local currency. Every time, without exception. If a terminal defaults to Australian dollars or prompts you to confirm a conversion, decline it and select local currency instead.
It is one of the smallest and easiest habits to build when travelling internationally and it consistently keeps more money in your pocket across a trip.
