As part of the state's "circuit breaker" lockdown, six fresh locally acquired Covid-19 instances are expected to be publicized today.
The new illnesses bring the total number of cases in the current outbreak to 60.
There were 51,033 tests and 20,585 vaccination doses administered in the 24 hours leading up to midnight.
The state administration and health experts are allegedly debating whether or not to extend the seven-day lockdown, which is set to conclude tomorrow.
There are also growing efforts to loosen regional limits.
A newly identified Covid-19 case traveled between Victoria and NSW, raising concerns about "stranger-to-stranger" transmission.
There are now 351 exposure sites linked to the disease, including country gas outlets in Wallan, Euroa, and Glenrowan.
In the state's latest 54-case epidemic, Covid-19 testing commander Jeroen Weimar claimed there were four to five cases of persons catching the virus from "fleeting contact."
"They don't know each other's names," Weimar told reporters Tuesday. "That is completely different from what we have observed before."
The increased infectiousness and rapid spread of the Indian form, according to Health Minister Martin Foley, will factor into the decision to extend the lockdown.
"That is one of a number of pieces of evidence that the chief health officer [Brett Sutton] and his colleagues will carefully consider," he explained.
Sutton called the new variety "an incredible beast" in a statement released today.
"This virus has progressed quicker than any other strain we've worked with, and we're witnessing transmission in settings and circumstances we've never seen before," he said.
"This implies we'll have to re-examine more than 300 exposure sites with this highly contagious strain in mind. This is not a task to be taken lightly.
"We're attempting to do something no one has ever attempted before: drive down the most difficult variety we've ever seen in a predominantly uninfected population.
"Many people will die if this strain is allowed to circulate unchecked as it has in other countries."
According to media reports, Professor Sutton's public health team was leaning toward recommending a lockdown extension as senior government officials gathered last night for a high-level briefing.
A representative for the state government declined to confirm details to AAP, but a final decision could be made as early as this morning.
The alarming spread of the Indian variety has prompted authorities to invite visitors to come forward for testing at 14 shopping areas around Melbourne in the last two weeks.
Weimar remarked, "We are now eager to begin draining the swamp to see what else is out there."
"Is there anyone else we haven't caught yet? Is there anyone else who has escaped the exposure sites?"
There are currently 4800 primary close contacts, with 75% of those testing negative.
It comes as part of a five-day vaccination blitz in Victoria, where elderly care and disability employees will be permitted to skip the line at ten immunization centers around the state starting on Wednesday.
From 9 a.m. to 4 p.m. (local time), express lanes for elderly care and disability workers will be open, with workers required to present evidence of employment.
It comes after the three-case Arcare Maidstone incident, which has now been connected to a South Australian hotel quarantine slip, exposing vaccination gaps among private aged care personnel and residents.
According to Senate estimates released yesterday, less than 10% of nursing home employees in Australia have been vaccinated as a result of federal government inspections.
