Coronavirus updates LIVE: Victoria records 20 new COVID-19 cases; Gladys Berejiklian says NSW border unlikely to close as Australian death toll stands at 103

A total of 20 new coronavirus cases have been confirmed in Victoria, the state's Health Minister Jenny Mikakos has said.

It is the eighth straight day that the number of new cases has been in double digits.

Ms Mikakos warned the state had been reporting a 2.5 replication rate this week. (This means on average an infected person spreads the disease to 2.5 other people)

The state government has previously said the replication rate should be below one.

"This has happened very suddenly," Ms Mikakos said.
