After a one-day respite, COVID-19 cases in the Australian state of Victoria rose again, prompting a move to make masks mandatory in metropolitan Melbourne and the nearby shire of Mitchell. Health officials on Sunday recorded 363 new cases in the past 24 hours. Two men and a woman in their 90s died, taking the national death toll from COVID-19 to 122. The new rule will be enforced from 11.59 pm on Wednesday night.

"There's no vaccine to this wildly infectious virus, and it's a simple thing but it's about changing habits," state Premier Daniel Andrews. "Common sense" will guide the new rules, and despite being mandatory, Andrews advised the measure be done "whenever practical". "If you are out of your home for one of the four (permitted) reasons, then you need to be wearing a mask and I stress it need not be a hospital-grade mask," he said, adding, "Any face covering is better than no face-covering."
