For Aussies here, just received the following message from my bank- "We don’t charge ATM withdrawal and foreign exchange fees when you access your Ultra transaction account overseas, or for online purchases with overseas merchants."

This is NOT a promotion trick, Ubank is and online only bank, part of the NAB. 

Will UBank reimburse ATM fees charged by Thai local bank?

What exchange rates will they be using?

This could be a better deal than Transferwise.
