Victorian aged care and disability workers given priority access to COVID-19 jab in 'five-day blitz'

Workers must present evidence of their employment to get a priority lane.

"We have concerns there isn't enough coverage and that is why we are stepping in," Victorian Minister for Disability, Ageing and Carers Luke Donnellan said.

"It has been available, but this is very much a call to arms of those workers on the frontline to come out and we will give you a priority lane so it makes it quicker and easier to get through it in a speedier time.

"Because we very much want to ensure we are protecting those people in the aged care facilities and disability sector from COVID-19."

Victoria has recorded nine new locally acquired cases of COVID-19 today, bringing Melbourne's evolving outbreak to 54 active cases.

Six of these new cases were reported in yesterday's daily COVID-19 update, but weren't included in yesterday's official figures, as they came in after the midnight deadline.

This means there are three new cases in addition to the 11 cases reported yesterday.

This morning, Health Minister Martin Foley said two of these cases were primary close contacts who were already in isolation, with the other case still under investigation.

There are no more mystery cases in Victoria.

Mr Foley said he didn't know if there would be an extension to the state's seven day lockdown, which is scheduled to end on Thursday, June 3 at 11.59 pm.

"As the acting Premier pointed out yesterday, there is every prospect that things might get worse before they get better," he said.

"We are not yet in a position to make that call."

Asked whether the "ring of steel" between Melbourne and regional Victoria could return, Mr Foley said it was "a day-by-day and case-by-case proposition".

"It all depends on what the recommendations from the Chief Health Officer and public health team are," he said.

"We've still got, particularly at Axedale and Cohuna, a number of people in quarantine. They might well turn positive. Let's hope not, but so far so good.

"As soon as the recommendation is made ... we will be talking to the people of Victoria about what the next stages are."

This comes as four infections have been linked to aged care homes, putting vulnerable residents at risk.

The first case was a worker at Arcare Maidstone, who tested positive on Sunday.

"That is at least confirming in our mind that this is all the one related cluster from the South Australian hotel breach," he said.

Another three cases were identified yesterday, including the son of the first case, a 99-year-old Arcare resident and an Arcare worker who also worked at a BlueCross Sunshine aged care home.

In good news, Mr Foley announced all other staff and residents at the Blue Cross facility had tested negative to COVID-19, with no further positive cases at Arcare Maidstone.

Contact tracers have identified 135 close primary contacts linked to this aged care cluster, including 89 residents and 46 staff, contractors and visitors.

Victorian testing chief Jeroen Weimar urged people to be proactive in coming forward for testing as, concerningly, many cases in the current cluster had been infected through "stranger to stranger" transmission.

"We have seen transmission in these places with very fleeting contact," he said.

"With previous variants, we are more used to transmission occurring in the home, in the workplace, where people know each other already ... These are quite different."

There are currently 4800 close contacts in isolation, with more than 320 COVID-19 exposure sites across Victoria.

Victoria has reported a total of 63 COVID-19 cases, including those in hotel quarantine, with more than 20,400 coronavirus vaccines delivered yesterday.
