ustralian officials visited their three nationals - part of a larger group of 17 Crown employees in detention - in Shanghai, Bishop told reporters in Canberra on Wednesday.
"We were able to provide advice and support. We provided messages from their families. There is an anti-corruption agenda of President Xi Jinping and gambling is one of the areas of interest, so we are subject to the laws of China." The consular visit comes a day after Australian authorities confirmed that three nationals, including Crown's head of international VIP gambling, Jason O'Connor, were arrested.
Eighteen Crown employees were initially detained, but one has since been released, Crown said last week.
The fate of the other 14 is not clear.
Analysts have linked the detentions - which sent Crown's share price tumbling - to Chinese laws banning casinos from advertising or promoting gambling in the Chinese mainland, for instance by offering credit to high-spending clients.
In October, Crown said "less than half" its international VIP revenue, or about 12 per cent of total revenue, came from Chinese high-rollers.
