Another 44 people have died from COVID-19 across Australia, while states and territories have recorded falls in case numbers.
Victoria recorded eight fatalities, while NSW had 27 — down from the record 52 deaths reported the previous day.
Queensland said three people had died and South Australia six, and more than 350 people across the country are in intensive care.
Meanwhile, Federal Health Minister Greg Hunt said more than four million people across the country are now eligible for booster vaccinations after the gap between a second and third dose was shortened from four months to three.
He told reporters: "The simple message is if you haven't previously been eligible or you are eligible and you haven't come forward for your first dose or your second dose or your booster, now's the time. Please don't wait.
"And so we'd encourage everybody to come forward. And an extra 4.2 million people [are] eligible for boosters as of today, moving from a four-month eligibility to a three-month nationwide eligibility since the second dose.
"Another very important thing is that we have seen a consistent decrease in cases, hospitalisations and ICU. When we look at the last 10 days, it's a decrease in hospitalisations around the country for people with COVID, of 487, and people with COVID in ICU is down 50 over that period to 367 as of yesterday."
In NSW, there are 2,799 patients with COVID-19 in hospital, 116 more than there were on Saturday.
Of those patients, 185 are in ICU, up from 182.
In Victoria, hospitalisations with COVID-19 have fallen by 16 to 873 patients.
There are 102 people in intensive care, nine fewer than on Sunday, with 33 of those on a ventilator.
About 38 per cent of Victorians aged over 18 have received a COVID-19 booster, after 16,298 doses were administered at state clinics on Sunday.
Experts have predicted a spike in COVID-19 cases following students returning to classrooms, and a new survey has forecast large numbers of infections could go undetected.
The survey found three in ten parents in NSW and Victoria don't plan to follow state government guidelines requiring twice-weekly rapid antigen tests of school students.
While 70 per cent of the 1,000 parents surveyed by consultancy firm Nature said they would follow the guidelines, 15 per cent said they would only use the rapid tests if their child had symptoms, 13 per cent said they would test once a week or less and two per cent would never test their children.
What's happening elsewhere?

South Australia reported six deaths and another 1,505 cases amid ongoing concerns for the state's indigenous communities.
