Phnom Penh Currency Guide
Cambodia mostly uses its local currency, the Riel. However the US Dollar is also widely accepted in small denominations.
ATMs can be found in central Phnom Penh. 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 Cambodian Riel or US Dollars before you fly.
For large purchases, it's a good idea to bring a credit card or debit card with you on your holiday instead of carrying a lot of cash.
