PERTH, Australia — The Australian west coast city of Perth will lift a three-day lockdown after no new COVID-19 infections were detected on Monday.

The lockdown of the city of 2 million people was called on Friday after a man who returned to Australia from a wedding in India infected two people in Perth last week.

Western Australia state Premier Mark McGowan said on Monday four days of lesser restrictions would begin at midnight.

“I wish we didn’t have to go into lockdown. But it has been necessary and it’s worked. This virus is so unpredictable,” McGowan said.

Nightclubs and the city’s casino would remain closed and customers would have to remain seated in pubs, cafes and restaurants for four days.

Western Australia has been the most successful part of Australia in preventing the coronavirus spread and also imposes the toughest border restrictions on states that have experienced clusters.

Perth’s cases of community transmission last week were the first in Western Australia in more than a year.
