Australian health workers will go door-to-door testing more than 100,000 residents in a coronavirus hot spot in suburban Melbourne that is threatening to undo the nation's success in battling the virus.
Victoria state on Thursday reported 33 new cases, the highest daily number in more than two months.
Premier Daniel Andrews says the testing aims to collect samples from half of all residents in 10 suburbs. He says the goal is to test 10,000 people daily over 10 days.
The tests are free and Andrews is urging people to see undergoing testing as a civic duty.
More than 1,000 military personnel are helping with the operation, while other states will help process the test results.
Australia has reported more than 7,500 cases of the virus, including 104 deaths.
