One of the money laundering syndicates linked with the Commonwealth Bank compliance scandal worked with drug smugglers who imported methamphetamine worth $315 million, the largest ice seizure in West Australian history.

The Hong Kong-linked syndicate used the CBA to launder more than $21 million, according to the statement of claim filed by financial regulatory agency Austrac against CommBank.

It is believed Westpac was also used by the syndicate to wash drug money, but it is unclear what methods were used, and whether these have also drawn the attention of Austrac.

In September 2015, WA Police seized 321 kilograms of ice and more than $1.4 million in cash from the syndicate after a series of raids around Perth.
