Three Australian citizens employed by James Packer's Crown Resorts Group have reportedly been detained in China amid an ongoing nationwide crackdown on corruption.
The three Australians are said to be members of Crown's sales and marketing team and one is reported to be a senior executive at the company -- one of Australia's largest entertainment groups.
"Crown believes that a number of our employees in China are being questioned by local authorities and at this time we can provide no further details," a Crown spokesperson told The Australian Financial Review.
The AFR reports that most of the detained staff are based in China have been interviewed over the past 24 hours.
The Department of Foreign Affairs said it was working to confirm the media reports.
"The Australian Government is aware of reports of the possible detention of a number of Crown International Group employees across China, including three Australians," DFAT told The Huffington Post Australia on Saturday morning.
"Consular officials are seeking to confirm these reports with the relevant Chinese authorities.
"If Australians have been detained, consular officials will seek to offer appropriate consular assistance in accordance with the Consular Services Charter."
Under a deal between Australia and China, the Asian superpower has 72 hours to inform Australia if they are holding one of its nationals.
Crown has a substantial presence in Macau, but casinos there have been targeted recently by the Chinese Government's anti-corruption drive.
