Koh Samui Currency Guide
The currency used in Koh Samui is the Thai Baht.
ATMs in Koh Samui can be found throughout most of the resort areas, particularly within the main shopping drags of Chaweng Beach and Lamai Beach. Most of these machines accept all the major credit cards and also have an English language option available. If you plan on withdrawing money or using your credit card while travelling, don't forget to notify your bank before you go for security purposes and to see what international withdrawal fees may apply to your card.
Before you jet off on your Koh Samui holiday, don't forget to convert some of your Australian Dollars into Thai Baht to have with you when you arrive. Thai Baht is available to pre-purchase from Travel Money OZ.
If you'd like the security that a credit card offers while travelling without the risk of racking up debt, consider purchasing a pre-paid travel money card. Cash Passports allow you to load your money in the form of Thai Bahts and other currencies onto the card. Your money can then be accessed at various ATMS and used wherever MasterCard is accepted. The Cash Passport card has both a security pin and signature required for safe spending.
