Victoria has recorded 22 new local COVID-19 cases in the 24 hours up until midnight on Tuesday as the state begins its first day of the extended lockdown.
Of the 22 locally-acquired cases reported, all are linked to the current outbreaks.
There was one new case in hotel quarantine.
Tuesday also brought just under 60,000 test results to Victorians, along with 18,099 vaccinations administered.
Victoria's active coronavirus case tally now sits at 118.
Premier Daniel Andrews is expected to make an announcement on payments to businesses on Wednesday.
Mr Andrews confirmed the lockdown was due to end Tuesday next week.
"We wish we could bring this in earlier, but we can't run the risk that there are cases out there that we don't know about," he said.
"There are changes of transmission that are not yet contained that we don't know about and if we would open up we would see how quickly this runs, we see how challenging this can become in a very short space of time.

"We need to avoid what is going on in Sydney at the moment. We are determined to do that."
Wycheproof's Bakery on Broadway was downgraded to a tier two COVID-19 exposure site on Tuesday evening.
The venue was listed as a tier one site after a positive case travelling from Melbourne to Mildura stopped at the bakery at the weekend of July 10 and 11.
"This is wonderful news for our community and staff," a Facebook post from the bakery read.
"We are awaiting test results, but pray they are negative."
Victoria has slammed the border shut to red zone arrivals as it spends at least another seven days in lockdown to quash the highly contagious Delta coronavirus variant.
From 11.59pm on Tuesday, Victorian residents in NSW and the ACT were no longer allowed to come home amid a two-week pause on issuing red zone permits.
Only authorised workers and those who apply for and receive an exemption are now able to travel between the two states, along with border residents.
