(Update with details on compensation, background)

March 10 (Reuters) - Australia's corporate watchdog said the country's six largest banking services providers have paid or offered A$4.7 billion ($3.10 billion) in compensation to customers who suffered losses for fees charged for services that were not provided.

The Australian Securities and Investments Commission (ASIC) said on Friday it undertook a review of the systems which led to wrongful fees being charged by the country's four biggest banks - Commonwealth Bank of Australia (CBA) , Westpac Banking (WBC) , ANZ Group (ANZ) and National Australia Bank (NAB) - plus investment bank Macquarie Group (MQG) and wealth manager AMP Ltd (AMP) .

The watchdog's order for customer compensation came at a time when each of the 'Big Four' - which account for the majority of lending in Australia - are being closely scrutinised for abusing their market dominance in the wake of scandals involving misleading financial advice, insurance fraud and interest-rate rigging.

The largest business lender in Australia, NAB, took the lead and coughed up A$1.49 billion in compensation as of the end of 2022, followed by CBA and Westpac coughing up a payout of A$1.13 billion and $1.03 billion, respectively.

ASIC said its final update on remediation figures "draws a line" under its eight-year long programme of addressing financial institutions' failure to provide ongoing services to fee-paying customers.
