Victoria has its deadliest day in the coronavirus pandemic, with 19 deaths and 322 new infections, including 105 "mysterious" cases with no known source.
The number brings the state's death toll to 229 and the national number to 314.
Fourteen of the 19 deaths were elderly care residents. The people who died were one man in their fifties, one woman in their sixties, two men in their seventies, one man and six women in their eighties, and one man and seven women in their nineties.
Victoria currently has 7,869 active coronavirus cases, including 1,065 in healthcare.
The Australian Medical Association has said it is "extremely concerned" after 590 healthcare workers contracted the virus in the past 14 days.
Nurses from Western Australia will land in Melbourne this week to provide reinforcement.
After peaking at 725 on August 5, Prime Minister Daniel Andrews said daily totals appeared to be falling due to lockdowns and mandatory mask wear.

"We are certainly seeing greater stability resulting from the cumulative effects of the third stage," he said.
But he warned the Victorians not to "beat us" and continue to obey the lockdown rules.
In his daily press conference, Andrews showed two videos of COVID-19 survivors who had permanent health effects, including a middle-aged woman who needed a breathing tube for a month.
“Think about the person who is most important to you. And then you think of them with a tube so they can breathe in the intensive care unit for 32 days. It's that serious, ”he said.
Victoria is introducing a free call-to-test program that allows a vulnerable person to call a tester home by calling a hotline within 48 hours if they want a COVID-19 test.
"We will go to people's homes and make sure they can be tested within 48 hours," said Health Minister Jenny Mikakos.
"This is to ensure that around 200 vulnerable Victorians have access to this new testing capacity every day."

On Sunday, Nick Coatsworth, Australia's deputy chief medical officer, said Victoria had passed the peak of the outbreak.
"It looks like we're on the plateau, but we're looking for the turning point that tells Victorians that their efforts will be rewarded," he said.
“We haven't seen that yet, but I have no doubt we'll see it. If you consider that the third level restrictions were almost on a plateau, the fourth level restrictions will produce an outcome. & # 39;
Around 500 new cases have appeared in Victoria every day for the past seven days, and on Sunday there are 394 new cases with 17 new deaths.
Dr. Coatsworth said the pandemic is challenging because you "never really know where you are on the curve".
The rate of spread of the virus is referred to as the "reproductive number" or R-0.

When the R-0 is one, R-1 means that each person with the virus is passing it on to another person.
Numbers above R-1 mean that a virus is spreading exponentially. However, when the reproductive number falls below one, the virus slowly gushes out.
COVID-19 has a natural median reproductive number of R-5.7, according to a study published in the journal Emerging Infectious Diseases, which explains why it exploded across Victoria.
Victoria's outbreak now has a base reproductive number of R-1 – or just below, said Dr. Coatsworth on Sunday.
"The ideal situation would be if we could see that reproduction number at 0.5," he said.
"We don't have enough data from the numbers right now to see if that approaches 0.5, but we will see that in the coming days up to the week."
Victoria Police Department fined 276 for violating lockdown rules
Police fined a total of 276 people for violating the Chief Health Officer's instructions, including:
• 37 for not wearing face covering when leaving home for one of the four approved reasons
• 25 at vehicle checkpoints
• 74 for curfew violations
• 27 fines for those who traveled to the CBD on Sunday or participated in a protest.
• A man was seen running down Edgedale Road in Kew overnight. He was stopped by the police and said he would only get cigarettes, even though he was aware of the curfew.
• A vehicle was in a parking lot in Campbellfield with four people with different addresses claiming they were just "hanging out". All four men were fined.
• Upon receiving a noise complaint, police visited an address in Wyndham and found 5 people in a garage who were drinking, smoking and listening to loud music. All five people were charged with a violation.
• A man was in Yarra, more than 3 miles from his address. He claimed he was going to meet friends for a drink.
• A man and woman had traveled over 3 miles to go to a playground in Wyndham and play with their children because they claimed they were tired of walking around them.
Six people were arrested on Sunday and 27 fined for violating restrictions in a lockdown protest called the Melbourne Freedom March.

Queensland recorded a new case of coronavirus, a traveler in hotel quarantine, Monday morning.
The elderly care homes in Queensland are now open to visitors again. Authorities are confident that two infected teenagers who avoided quarantine did not spread coronavirus.
Officials were on high alert over an outbreak linked to the women who moved around the community for a week after returning from Melbourne in July.
"Today was the very important day," said Prime Minister Annastacia Palaszczuk, referring to the end of the two-week period since police isolated the women.
"The restrictions on care for the elderly are being lifted, which means a lot to families, especially in the last week when they could not see their loved ones."
Jeannette Young, chief health officer, said the Bolton Clarke aged care facility in southwest Brisbane would have to remain closed for a day and a half.
"Until we have confirmation that the potential outbreak is over," she said.
According to The Australian, grim secret modeling by the Victorian government leaked Wednesday estimated the daily case load would rise to 1,100 by the end of this week.
The bad prognosis showed that the number of cases would then be over 1,000 per day and would not fall below the current level until the end of August.
But Prime Minister Daniel Andrews said no one in his administration or the federal government was aware of the modeling.

Professor Tony Blakely from the University of Melbourne also said The outbreak has already peaked thanks to wearing the mask.
& # 39; It looks like the curve turned on July 30th. But more importantly, it makes sense. & # 39; he said.
The professor said July 30 had passed about a week after the Victorian government introduced mandatory mask-wearing – which is also slightly more than the virus's five-day incubation period.
Wearing masks seems to have bent the curve, which is what would be expected. In other words, the numbers would now be higher without a mask and much higher again without level 3 restrictions, ”he said.
He predicted a significant drop in smoothed day numbers would occur about 10 days after Victoria put restrictions on Level 4 on Thursday.
He said once the numbers drop to around 200 a day, which he expects the fourth level restrictions to be hit, the contact tracing teams will be less overwhelmed and the state will be able to keep the numbers down.
Professor Tony Blakely's five-day averages chart predicted that Victoria's breakout has already peaked and is now on its way down. Professor Blakely is optimistic that face masks and the lockdown have already reduced virus transmission

As of Sunday, the state recorded 394 new cases, bringing the state's total to 14,659, of which 7,854 are active.
Dr. Coatsworth urged everyone to download and activate the government's COVIDSafe app on their cell phones. This is necessary now as states other than Victoria are loosening their locks.
"We see what happens when you have an essentially open economy like you do in New South Wales," he said.
"And this is where COVIDSafe comes into its own."
In Sydney's western suburbs, 544 people were tracked through the app, which resulted in the positive identification of two new COVID-19 cases, said Dr. Coatsworth.
New South Wales recorded 10 new coronavirus cases on Sunday, only one of which was a returned overseas traveler in hotel quarantine.
