New York Currency Guide
New York uses the US Dollar.
ATMs can be found all through New York, particularly on the main thoroughfares, in transport hubs and shopping districts. 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 check what international withdrawal fees may apply to your account.
Before you leave home, it is important to convert some of your Australian Dollars into US Dollars to have with you when you arrive in New York. US Dollars are available to pre-purchase from Travel Money Oz before you fly.
If you plan on hitting up the department stores and shopping districts in New York City, consider bringing a credit card or travel money card with you instead of carrying a lot of cash. If you don't have a credit card, consider a prepaid Multi-currency Cash Passport™, which lets you access your money in the form of US Dollars from ATMs and use wherever MasterCard® is accepted.
