Perth alone has a population of almost 2 million.\n"I know for many Western Australians, this is going to come as a shock," McGowan said while announcing the lockdown.\nRestaurants, bars, and gyms will be shutdown, and schools, which were scheduled to reopen this week, will remain closed.\n"The City of Perth Pandemic Response Team has been activated and is working to ensure all necessary measures are put in place across the city."\nUntil January 31, Australia hadn't seen a single instance of community COVID-19 transmission in nearly ten months, reports the Times.\nIn fact, both Australia and New Zealand rang in the New Year with large celebrations and gatherings, as neither were impacted by COVID-19 lockdowns at the time.\nBoth nations have been implementing quarantine hotel measures for international travellers since last spring. Canada has announced that it is following suit as early as this Thursday, February 4.
