What is the best way to get the highest exchange rate for money (AUD) when going to Thailand? We are staying in Patong (Phuket), Koh Samui (Chaweng) & Koh Pha Ngan. We have a visa debit card that has NO charges or fees from our bank in Australia & no conversion percentages etc. The only fee we would likely get charged is the 150 baht that is apparently standard on most ATM's in Thailand.
Would we get more for our money if we were to exchange cash brought with us at an exchange booth? Or if we were to withdraw it from at ATM? Say for example if we wanted to exchange $500 AUD in cash at an exchange booth, would we get more baht doing it that way? Or would we get more withdrawing equal to $500 AUD in baht from an ATM. (With no charges from our bank, only the possible 150 baht from the Thailand bank)
Im not sure how the exchange rates work. Do ATM's have higher rates than the booths? Would we get more for our money doing one way over the other?
