Australia’s second most-populous state, Victoria, has reported its biggest jump in coronavirus cases since late March, forcing it to expand stay-at-home orders to two more suburbs and sending nine public housing towers in a complete lockdown.

The southeastern state recorded 108 new cases, up from 66 on Friday and more than 70 new cases in each of the previous four days, forcing authorities to reimpose lockdowns in more than 30 suburbs earlier in the week.

“These numbers are a very real concern to all of us,” Victorian Premier Daniel Andrews told a news conference.
