Belgium Currency Guide
Belgium uses the Euro.
ATMs aren’t widespread across Belgium, but Brussels has loads, so it’s best withdraw enough Euros while you’re in the nation’s capital. You can use your major credit cards in most ATMs in Belgium.
Cash is king in Belgium. You can exchange your dollars into Euros here in Australia with great rates at Travel Money Oz before you go or change it when you arrive in Belgium. You can change money at exchange bureaus at train stations and airports or in Belgium banks. Banks are generally a better option with lower fees and better exchange rates.
If you'd like the security that a credit card offers without the risk of racking up debt while travelling, consider purchasing a prepaid travel card. A Multi-currency Cash Passport™ allows you to load your money in the form of Euros and other currencies onto the card. Your money can then be accessed at various ATMS and used wherever MasterCard® is accepted. The Multi-currency Cash Passport card has both a security pin and signature required for safe spending.
