Meanwhile demonstrators who attended the third day of recurring Melbourne protests have been encouraged to get tested as a fellow mob member battles COVID-19 in hospital.

Victoria's health department has confirmed a person is being treated in hospital after attending Wednesday's at-times violent rally.

"Public health investigations are under way," a spokesman said in a statement on Thursday afternoon.

"We are urging protesters to get tested should they experience COVID-like symptoms, no matter how mild."

The infection will be included in Friday's official case tally.

The COVID-positive protester was among a mob of 400 to 600 who swarmed the Victorian capital on Wednesday, despite stay-at-home orders and repeated warnings from authorities.

Chanting "every day" from the Shrine of Remembrance, hundreds without masks, some still wearing high-visibility clothing, marched through the city to the war memorial.

Riot squad members fired tear gas and other non-lethal rounds when rioters became increasingly hostile and refused to leave, with two officers injured and 215 arrests.

The demonstrations initially began in opposition to mandatory COVID-19 vaccinations for the construction sector and the closure of building site tea rooms, but have since turned into wider unrest.

A fourth day of the planned protests was a non-event, with demonstrators largely a no-show on Thursday despite flagging potential meeting sites.

Police pounced on protesters before they were able to gather in significant numbers, making 92 arrests.

SEE THE ROADMAP TO REOPENING

Meanwhile, stranded Victorians fully vaccinated against COVID-19 will soon be allowed to return home from Greater Sydney.

From September 30, double-dosed Victorians stuck anywhere in NSW can come home if they return a negative test 72 hours before departure, isolate at home for 14 days and get tested at the start and end of quarantine.
