Just got an email from Macquarie Bank and they indicated that they would no longer charge international currency conversion fees (2.5%) from 14 July 2016. This would be the second debit card (the first being Citibank Plus) that does not charge this fee.
Do note that the $5 overseas ATM and international transfer fees still apply. So Citibank still wins, though Macquarie's website is much easier to use. The platinum debit also includes concierge service and some insurance which requires a monthly deposit of $4k. No monthly account fees.
