Melburnians visiting each other in their homes has become a key concern of health authorities as the risk of transmission is 20 times higher when people are indoors together, Chief Health Officer Brett Sutton says.
Victoria recorded 21 new COVID-19 infections in the last day. Seven people have died from the virus, including a man aged in his 60s, three men in their 80s and one man and two women in their 90s, bringing Victoria's death toll to 757.
Melbourne's crucial 14-day rolling average of new coronavirus cases, which will decide if the state can come out of lockdown, has dropped to 39.3.
Professor Sutton said the risk of infection was about 20 times higher when people are inside.
"It is a combination of indoors which is 20 times more dangerous than outdoors. And the length of time you spend.
"There are brief encounters indoors, as you get your takeaway coffee, it is much less of a risk. But if you are indoors for a protracted period of time that is exactly when transmission occurs. People need to be aware of that."
