Victoria is expected to report more than 600 new cases of COVID-19, with more deaths today.
It comes after the State yesterday had 723 new cases in what was the worst pandemic day.
Yesterday, 13 deaths were confirmed too.
On Thursday, Prime Minister Scott Morrison and Prime Minister Daniel Andrews held talks on implementing stringent new stage four constraints for Melbourne.
A New Zealand-style lockout was debated as a potential choice-which saw all businesses closed except for critical services.
The PM said the spread of the virus was “of great concern” adding that “we can not rule out additional restrictions or limitations to stop this outbreak.”
“We have been in this lockdown now for some weeks, and we are not getting the results we would hope for,” he said in Canberra on Thursday morning.
“And as a result, the further measures that are taken are certainly necessary.”
Mr Andrews revealed on Thursday that wearing masks outside the home would be mandatory across the state, including in regional Victoria, and that six more local government areas would face additional restrictions.
Until 11.59pm on Thursday night , people living in Colac Otway, Greater Geelong, Surf Coast, Moorabool, Golden Plains and Queenscliffe will be unable to meet others or have visitors at home.
There were 877 reported cases and 57 deaths linked to aged-care facilities confirmed.
