Penang Currency Guide
Penang uses the Malaysian Ringgit.
ATMs can be found all throughout Penang particularly in the heavily populated areas and around the tourist areas like Georgetown. 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.
Before you leave home it is important to convert some of your Australian Dollars into Malaysian Ringgit to have with you when you arrive. Malaysian Ringgits are available to pre-purchase from Travel Money Oz before you fly.
For large purchases, it's a good idea to bring a credit card with you on your holiday instead of carrying a lot of cash.
