Australia’s gambling operators are in full damage control mode after the government ordered their venues to close for up to six months to contain the COVID-19 coronavirus outbreak.

On Sunday, Australian Prime Minister Scott Morrison ordered all bars, restaurants, clubs and casinos to close their doors by noon on Monday. The closure, which is intended to minimize further spread of the coronavirus, is set to last “at least six months,” dealing a possibly mortal blow to the nation’s casino firms.

Crown Resorts, which was forced to close its Melbourne casino’s main gaming floor this weekend after losing its exemption from coronavirus-related containment measures, said Monday that its hotels would continue to operate “in a reduced capacity” but all other activities were effectively toast.

Crown suspended trading in its shares last weekend ahead of its Melbourne announcement, a move that was followed on Monday by rival The Star Entertainment Group, which said its trading halt would last until Wednesday. Reports emerged this weekend that customers at The Star’s flagship Sydney casino weren’t abiding by the company’s stated social distancing policies.
