VICTORIA has recorded 12 new locally-acquired COVID-19 cases since Friday.
The Department of Health confirmed all of the cases were linked to the current Delta outbreaks.
Ten of the 12 cases were isolating throughout their entire infectious period.
There were also 39,846 coronavirus test results recorded in Victoria on Friday, as well as another 19,281 vaccinations.
Victoria's active COVID-19 case tally now sits at 169.
The numbers came after Premier Daniel Andrews called for a ring of steel around Sydney as NSW declared a national emergency.
Coronavirus case numbers continue to climb in NSW, with 136 cases announced on Friday.
Mr Andrews said it was a "national responsibility" that Sydneysiders were locked into Sydney.
"We need a ring of steel around Sydney so that this virus is not spreading into other parts of our nation," he told reporters on Friday.
"Let's focus on what's going on in Sydney, let's focus on not spreading what's going on in Sydney across the rest of our country.
"We will finish up with the whole country locked down if we don't do this properly."
The federal health department also updated their eligibility criteria for Pfizer vaccinations to include people who are pregnant.
The change comes after the Australian Technical Advisory Group on Immunisation (ATAGI) and the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) made a joint statement in June confirming the Pfizer vaccine was safe for pregnant people.
