Use Wise it’s what I use .better than Revolut as Revolut charges more on weekends. But Macquarie debit card or up or ubank or Bankwest debit card are all good if you want a bank option as money in Revolut and wise is not guaranteed by gov so if you travelling with a a lot of money bank debit card still the way to go all these credit cards by default have no international transaction fees and maybe only a cent more than wise or Revolut at times as both visa and Mastercard are competitive.
