What is Dynamic Currency Conversion?

When you pay overseas, the terminal may offer to charge you in AUD. It sounds convenient but uses a terrible exchange rate + fees. ALWAYS decline and pay in local currency.

Which cards have no foreign transaction fees?

Many travel cards: 28 Degrees, Bankwest Breeze, ING Orange, HSBC, and most premium Amex cards. Some have annual fees, others are free.

Should I get travel money or use my card?

A no-fee travel credit card plus a backup debit card is usually best. Cash is needed for small vendors but cards give better rates and protection.
