Shares of Australia's "big four" banks, ANZ Group Holdings (ASX:ANZ, NZE:ANZ), Commonwealth Bank of Australia (ASX:CBA), National Australia Bank (ASX:NAB), and Westpac Banking (ASX:WBC, NZE:WBC), all inched up in recent trading on Friday after the Australian Banking Association said on Thursday that banks will offer support to customers experiencing heavy rainfall and flooding in north and north-west Queensland.

The banks will offer help via the deferral of upcoming credit card payments, deferral of scheduled loan repayments, providing emergency credit limit increases, restructuring existing loans, waiving or refunding fees and charges, as well as offering additional finance to help cover cash flow shortages, depending on the circumstances of the customers.
