The enforcement investigation into Entain Group Pty follows an extensive supervisory campaign that examined entities within the corporate bookmakers sector, the Australian Transaction Reports and Analysis Centre (AUSTRAC) said. "Reporting entities have a responsibility to ensure they identify, assess and manage risks of money laundering and terrorism financing, develop adequate processes and devote the necessary resources to comply with their AML/CTF obligations," AUSTRAC Chief Executive Officer Nicole Rose said.

Entain, which is the owner of top Australian sports betting brands Ladbrokes and Sportingbet and holds around one-sixth of the country's online betting market, did not immediately respond to a Reuters request for comment outside of working hours.
