Authorities on Sunday added almost 100 new venues and times to the rapidly growing list, while confirming five new cases had been discovered in the community.
The exposure sites added overnight included major supermarkets and department stores.
Aldi at Sanctuary Lakes Shopping Centre, Big W in Craigieburn and Coles at Point Cook Shopping Centre were added to the Tier One list.
The Sanctuary Lakes Shopping Centre and Northland Shopping Centre were also added as Tier two sites
As of Sunday night, 40 people had tested positive, contact tracers had identified more than 4000 primary close contacts and the list of exposure sites and times had grown beyond 270. That figure includes many venues visited on multiple occasions.
Tier one exposure sites — prompting a 14-day self-isolation period — added to the list on Sunday included the aged care facility, supermarkets, department stores, bus routes and a kindergarten.
Two of Sunday’s new cases, identified from a little more than 45,000 tests, were close contacts in quarantine, one was linked to an exposure site and two were under investigation.
Mr Weimar was concerned the infection of the aged care worker — who he stressed was tested immediately after developing symptoms — was yet to be traced back to an identifiable source.
“At this point in time this is the biggest priority for us to make sure we fully understand and wrap ourselves around both where the cases come from and where those chains are,” he said.
Mr Weimar said the Altona woman had received her first jab but only a third of the staff at the Maidstone facility had been vaccinated under the federal government’s program, along with more than half of the residents.
The aged care home has gone into an even deeper lockdown in response, with residents combined to their rooms.
Scores of people who queued in near-freezing temperatures at the walk-in line at the Royal Exhibition Centre in Melbourne on Sunday morning were turned away, sparking heated scenes caught on video.
One of those in the queue said they had been at the centre for three consecutive days and another said they had failed repeatedly to get through to the Victoria Health vaccination line.
“I’ve tried 200 times to call the line and I can’t get through,” the man said.
“The ineptitude is just staggering.”
Currently, there’s no online booking system for those seeking a jab, meaning all appointments must be booked over the phone.
Victorian Health Minister Martin Foley told people not to give up trying to call and reminded them they could also contact their GP about getting a jab.
