The Australian state of Victoria - home to its second largest city Melbourne - is set to enter a snap lockdown late on Thursday after it recorded two more local cases of the virus.The latest outbreak brings the total number of virus cases there to 18.
This is the fifth lockdown in Victoria has experienced since the pandemic began. It will last until Tuesday.
The decision by Victoria means that about 40% of Australia's population is now under a stay-at-home order, BBC reported.
"You only get one chance to go hard and go fast. If you wait, if you hesitate, if you doubt, then you will always be looking back wishing you had done more earlier," Victoria Premier Daniel Andrews said.
Residents in the state of 6.6 million people will have to stay home except for grocery shopping, essential work, exercise and getting vaccinated.
Melbourne had largely avoided new cases despite an outbreak in the neighbouring state of New South Wales, home to the country's largest city Sydney.But earlier this week, a team of Sydney furniture movers travelled to Melbourne, leading to a spread in cases.
New South Wales is also in a five-week lockdown which will last until the end of the month.
