There is uncertainty as to whether the Australian Grand Prix will go ahead this weekend in Melbourne, after another six cases of coronavirus were confirmed in Victoria.
One of the latest cases attended the women's T20 Cricket World Cup final at the MCG and another the Golden Plains music festival.
The infected people - all men aged between 30 and 70 - were announced on Thursday and bring the total number of Victorian cases to 27.
One of the men attended Sunday's MCG final, watching the game from level two of the members stand while infected, the Department of Health and Human Services confirmed.
More than 86,000 fans attended the final.
It was also confirmed that a person infected with the virus attended Golden Plains at Meredith, west of Melbourne on March 7-9.
But a health department investigation has determined the individual wasn't unwell with the infection during the festival, its organisers say.
“As a result, no further public health action is required by festival attendees, including workers, volunteers and artists,” they said in statement on Friday.
Confusion reigns over Australian GP
There are doubts over the Australian Grand Prix this weekend at Albert Park, with the BBC and Sky Television Association reporting it will be postponed.
McLaren has withdrawn from the Formula One season opener after a team member tested positive for coronavirus.
Six-time F1 champion Lewis Hamilton says it is shocking the event will proceed.
Asked why he thought that was the case, Hamilton told reporters: “Cash is king, but I honestly don't know.
“The fact is we are here and I want everyone just to be as careful as they can be.”
Eight F1 team staff are being quarantined and tested for the virus in Melbourne but there are no confirmed plans to cancel the event, although this still a strong possibility.
Federal finance minister Mathias Cormann said whether the event goes ahead is a matter for its organisers.
“The government certainly hasn't made any determination to prevent the event from happening,” he told ABC on Friday.
“We act on medical advice, and we don't have any medical advice in front of us that this should be cancelled, but we are obviously in a rapidly evolving situation. If that advice were to change our approach to it would change accordingly.”
Victorian Health Minister Jenny Mikakos earlier stressed if people are unwell they shouldn't be going to work or events, whether it's F1 or a wedding.
“They should be self-isolating and staying home and potentially be tested,” she said.
