I recently tried two different ATMs in Thailand and the Thai Banks wanted to charge 350 baht for the ATM transaction. It seems that the charge is now 350 baht if your card is a Mastercard which is what the Macquarie debit card is. That is about $15 AUD to withdraw some cash!!
I believe Visa cards are still 250 baht. Wise is a Visa card but has monthly ATM limits.
The two banks I tried were Bangkok Bank and TMB.

Macquarie don’t charge you, the ATM provider you are using is charging
