Australian casino operator The Star Entertainment Group has been hit with a financial penalty after breaching COVID-19 rules at its flagship Sydney casino.

On Monday, the Liquor & Gaming New South Wales regulatory body announced that it had imposed a AU$5,000 penalty on The Star for allowing guests at its eponymous Sydney casino to consume alcohol while standing and mingling over the weekend.

All NSW venues that have been cleared to resume alcohol sales following the country’s pandemic shutdown are required to ensure patrons are seated while quaffing pints and cocktails. Liquor & Gaming NSW compliance director Dimitri Argeres said The Star was “aware of its obligations” due to the regulator having paid two previous visits to the Sydney casino over the past two weeks to ensure compliance.

The Star partially reopened its Sydney venue in the first week of June, leading to a full reopening at the start of this month. But the venue’s ability to remain open could be in jeopardy after The Star confirmed Monday that one of its guests had tested positive for COVID-19 earlier this month.
