A customer uses a National Australia Bank (NAB) automatic teller machine (ATM) in central Sydney November 12, 2014. National Australia Bank said on Wednesday it was moving to settle a class action brought against Australia's major banks over fees for late payment, opening the door to millions of dollars in compensation for disgruntled customers. The class action, Australia's largest, was brought in August by law firm Maurice Blackburn against NAB, Australia and New Zealand Banking Group Ltd, Westpac Banking Corp , Westpac units St George and BankSA, and Citigroup Inc's Citibank over late payment fees that it claims were excessive and unfair.
