Victoria’s COVID-19 testing commander Jeroen Weimar said on Friday that there are 34 coronavirus cases spread across five households in Hallam, Clyde, Narre Warren South and Cranbourne North.

He said members of those households were visiting relatives when they shouldn’t have been.

“We’ve also seen in this particular cluster visiting of houses beyond the 5km radius, so these five houses in this particular cluster have had, unfortunately, some members of those households visiting other households and it is that limited amount of contact, relatively infrequent contact between these five households that has now meant that we have 34 people in five houses experiencing or living with a very real threat of the coronavirus,” he said.

Premier Daniel Andrews said households visiting each other was a “real issue” and it was “disappointing” to see families ignoring the rules.

“The rules are in place for a reason and anyone who undermines this, undermines entire strategy and it means the rules will be on longer,” he said.

“If you break the rules, particularly if you are breaking the rules in your home or somebody else’s home, where there is no infection control, there is no formality, it is by its very nature, close contact for potentially prolonged periods, all you will do is spread this virus.”

The Premier also had stern words for those who breached COVID-19 rules to protests in Victoria.

He said protesting was a risk that no one should be taking at this time, regardless of what the protest is about.

“Protest at this time selfish, irresponsible, damaging and unlawful. Don’t do it, or Victoria Police are deal with it. And Victoria Police will have no choice but to do that,” Mr Andrews said.

“The only thing we should all be collectively protesting against is this virus, by following the rules, and getting out of these rules as quick as we possible can.”

Mr Andrews urged residents to focus on the positive steps the state has been taking with decreasing cases and some easing of restrictions.

“People should be positive and optimistic this strategy is working, and therefore, let’s not any of us do anything to undermine that,” he said.

“I’m proud and grateful to the vast majority of Victorians doing the right thing. Sadly, even a strategy that’s got 90% plus people signed onto it, not pleased to be in the predicament, but that’s the reality we face, can be undermined by the small number of people who do the wrong thing.”
