Westpac issues Visa Debit cards to its transaction account holders – including those with a Westpac Choice account. A Westpac Visa Debit card can be used for free with any Westpac ATM in Australia and this includes banks owned by Westpac, so St. George, BankSA and Bank of Melbourne. Westpac is also part of a global alliance with international ATMs, so some overseas withdrawals may be free.
