Twelve new coronavirus cases were recorded in Victoria today, Sunday, with three of those linked to The Butcher Club in Chadstone.

Premier Daniel Andrews also announced that a man in his 80s in an aged care facility had died, bringing the state’s death toll to 806.

In terms of the Chadstone cluster, chief health officer Prof Brett Sutton said casual contact or shared facilities such as the public toilets contributed to the transmission.

“So it is a salient lesson,” he said. “People who work closely together can be part of a cluster, and all of their household contacts then become the secondary cases, and then the tertiary cases are where some of those household contacts go to their essential workplaces, again, before potentially they are infectious.”

While case numbers continue to remain low, Mr Andrews urged Victorians to remain vigilant as the weather heats up so that Melbourne can move to the next stage of eased restrictions in two weeks.

“If you want to spend summer at the beach, then that will be the time to do that if we don’t do anything silly, anything selfish, right now,” the Labor leader said touching on the video of hundreds of people swarming St. Kilda without precautions.

“I want to thank all of those Victorians who were going to the beach and did so in full accordance with the rules. All of those Victorians who went to the park, who followed the rules and were able to connect with others, were able to get some sunshine and some fresh air. Heaven knows Victorians have earned it. But it’s got to be done in the right way.”

Mr Sutton then went on to stress that the number of untraced cases recorded in the areas in and around East Malvern, Caulfield East, Caroline Springs, Deer Park and Braybrook remained “a concern”.

“One single case of unknown acquisition … might represent five true cases out there, might represent 10 or 15 true cases out there, because we don’t know where they got it from,” Sutton said.

Meanwhile, New South Wales reported no new locally transmitted cases on Sunday for the ninth day in a row. There were only two cases in hotel quarantine.

“We are now encouraging public servants to physically return to work in their offices in a Covid-safe way, which will help stimulate city-based businesses and create more jobs across the state,” premier, Gladys Berejiklian, announced.

“The government will continue to review health advice and aim to ensure we keep people safe and at the same time allow them to return to their normal lives as much as possible.”
