Commonwealth Bank of Australia is pushing back on a money laundering case brought by Australian regulators. 

Australia's financial intelligence agency Austrac slapped the bank with 100 contraventions of money laundering and counter-terrorism laws in December last year, in addition to initial claims it made in August. On Friday, the bank denied 89 of the extra claims, but admitted to 11 in part.

The bank admitted to 98 instances where the bank made «errors» relating to suspicious matter reports, saying it filed them late, or did not file them at all, in an update on its website. It stood by 56 breaches relating to its obligations to conduct due diligence on customers.

CBA also admitted failing to file 53,506 reports about cash deposits above $10,0oo, known as threshold transaction reports, in time. However, it argues these should be treated as one breach, because they were caused by the same coding error.
