There will be further restrictions on residents’ ability to leave home.
Australia has been more successful than many other countries in tackling Covid-19, but cases are rising in Victoria.
What are the new restrictions?
The only valid reasons for leaving home during these hours will be work, medical care or care-giving.
Restrictions will also be tightened across regional Victoria from Thursday, with restaurants, cafes, bars and gyms closing from 23:59 on Wednesday.
To ensure these rules are observed, police will be given additional powers, Mr Andrews said.
Why did Victoria become the epicentre of Australia’s outbreak?
Then, about five million residents of Melbourne were told to stay at home for six weeks.
