Victoria has recorded six new local cases of COVID-19 as health authorities race to track down the source of a mystery infection detected yesterday.
The six cases were all linked to current outbreaks and were in quarantine throughout their entire infectious period.
There were seven locally-acquired cases in the reporting period to midnight, which includes the mystery case found in the traffic controller announced yesterday.
LIVE UPDATES: The data offering virus-stricken Sydney a glimmer of hope
https://twitter.com/VicGovDH/status/1420513050025553920"Investigations continue into a locally-acquired case reported yesterday," the Department of Health said on Twitter.
The man worked for two days while potentially infectious at the Moonee Valley drive-through testing site, prompting the clinic to become a Tier Three exposure site on July 25 and 26, between 7.20am and 6pm.
Anyone who visited the testing clinic during these times is urged to monitor for symptoms.
Several new exposure sites have emerged across Melbourne following the man's positive case.
Whether the man contracted the virus at the testing site is unknown, but health authorities are investigating all lines of enquiry.
"We'll look through to see whether anyone who's subsequently tested positive has gone through that testing site, but we have to do all of the investigations as to where he might have acquired it," Chief Health Officer Professor Brett Sutton said yesterday.
Despite the latest lockdown and stringent restrictions still in place, there are bold plans to host 60,000 racegoers on each day of the Melbourne Cup Carnival at Flemington Racecourse this year.
There are also hopes to get 100,000 people back to the MCG for the AFL Grand Final.
Vaccine passports and rapid testing could be key to the events going ahead with ambitious crowd numbers.
The Victoria Racing Club said it would be guided by government guidelines on vaccine passports.
