Hundreds preparing to descend on Melbourne CBD in protest.

Police have vowed to crack down on anti-lockdown protesters planning a Melbourne march in a "blatant breach" of COVID-19 rules.

In a statement on Thursday, Victoria Police said it was aware some people may be planning to protest in Melbourne's CBD on Sunday.

A Facebook event has called on people to march in opposition to the city's six-week shutdown and claimed to be part of a broader movement of planned protests.

"Let's blow this one up and fill up the streets to show these criminals we won't give up our country and livelihoods without a fight," the event description reads.

It had more than 100 confirmed attendees and 400 expressions of interest late on Thursday evening.

If they turn up, Victoria Police said it wouldn't hesitate to hand out $1652 on-the-spot fines or arrest protesters.

"This is a completely blatant breach of the chief health officer's directions and puts Victorian lives at risk," police said.

Victorians told not to stockpile meat.

Victorians are being urged not to panic buy meat as the state's abattoirs cut back operations under industry restrictions to help slow the spread of coronavirus in workplaces.

The reduced production is part of a sweeping stage four Melbourne lockdown that has progressively come into effect since Sunday.

Victoria recorded 471 new cases of COVID-19 and eight more deaths on Thursday, far fewer than the record-breaking 725 cases and 15 deaths reported on Wednesday.

Victoria Health believes the rate of new COVID-19 infections in the state will start to fall more significantly in the next week.

There are now 533 Victorians in hospital with coronavirus in the state, and 42 of those in intensive care. A young child is among six people under the age of 40 critically ill.

Thursday marked a move to tough new restrictions on workers and businesses in Melbourne, while regional Victoria officially entered stage three rules.

JobKeeper eligibility tweaked for businesses.

It will be easier for businesses hurt by coronavirus to apply for JobKeeper after the end of September under changes made by the federal government.

Treasurer Josh Frydenberg says the changes, along with more Victorian companies joining the scheme, will add another $15.6 billion to the cost of the wage subsidy program.

Previously, businesses and not-for-profits hoping to receive JobKeeper from September 28 to January 3 would have to show a significant fall in turnover in both the June and September quarters.

But under the nationwide changes, they will just have to show turnover has significantly fallen for the September quarter, compared to the same period last year.

Businesses and not-for-profits will have to prove their eligibility again in January, but it will be based on the December quarter rather than the two previous quarters as well.

Staff who were employed as of July 1 will now be able to access the program.

The payment is currently $1500 a fortnight but will reduce to $1200 for full-time employees from October to December.

It will then reduce again to $1000 until March.
