Turning Around

Commonwealth Bank of Australia is entangled in an ongoing money laundering case. The bank is accused of breaching the Anti-Money Laundering and Counter-Terrorism Financing Act over combined cash deposits of A$624.7 million which passed through the bank's smart ATMs.

Last week, the bank said it was a step closer to a resolution after orders for mediation were made public. The bank was hit with 53,000 breaches of the anti-money laundering and counter terrorism financing act last year.
