In the past 24 hours, 502 new cases have been confirmed - well ahead of the previous single-day record of 469 back in March.

Of those cases, 484 are in Victoria, 16 have been reported in New South Wales. There's a single case in South Australia and a new case in Queensland.

Victorian Premier Daniel Andrews wasn't impressed at the statistics which revealed that half of the new COVID cases now admit they failed to isolate after being swabbed for COVID-19.

"I'm very unhappy and very sad to have to report that,'' he said. "That means people have felt unwell and just gone about their business. They have been at the height of their infectivity. And they have just continued on as usual."

You've heard it before but he told people if they feel unwell, to get tested and then self-isolate.

"Nothing else is acceptable. You must go and get tested when you feel sick. That is the only thing that you can and must do. And if people don't do that, then we will continue to see numbers increase. I'm being as frank, as blunt, as clear as I can."

Up the road in NSW, Gladys Berejiklian was just as forthright: "Any business that doesn't do the right thing, will have the book thrown at them."

Libraries beware.

Ms Bereijklian might not hold sway in the ACT but they're channelling her with one repeat restaurant offender copping a $5000 penalty for repeated breaches.

And while we're talking breaches, there's the none too small matter of Queensland police looking for almost 200 people "missing from self-quarantine".

Police would "absolutely" try and find the 185 people still unable to be tracked down, out of about 13,000 directed into self-quarantine since April.

Deputy Commissioner Steve Gollschewski wasn't too perturbed: "But as I said, a number of them are already at a period where any risk they posed to the community has passed because of the time that's gone by." OK, then.

From a global perspective, infections have surged past 15 million; a mask-free President Donald Trump warned the US "it will probably, unfortunately, get worse before it gets better" and China announced that passengers on inbound flights must provide negative COVID-19 test results before boarding.
