Locations and events listed include Sunday night's T20 Cricket World Cup Final, the Rebels vs Lions rugby game at AAMI Park on Saturday evening, and La Trobe University's Bundoora campus.

In relation to the T20 Cricket World Cup Final at the MCG, which drew crowds of more than 86,000 people, authorities specified the exposure site as the MCC Members Level 2.

Other locations include train stations, restaurants, supermarkets, and parks, while a number of overseas flights landing in Melbourne were also listed.

A person who attended the Golden Plains music festival south-west of Melbourne on Sunday has also since been diagnosed with the virus, Victoria's Health Minister confirmed.

Anyone who was at any of the sites should be aware of their health and seek medical advice if they become unwell.

La Trobe University sites 'deep cleaned' after student infected

Earlier, La Trobe University announced a student at its Bundoora campus had tested positive for COVID-19.

The university said in a statement on Thursday afternoon that on the advice of the Department of Health and Human Services (DHHS) the campus would remain open.

"The affected individual is a La Trobe student who has attended class within the past week," the statement said.

"The student is receiving medical treatment and the University has offered its full support to the student via the Health Department.

"All staff and students with whom the student came into contact have been identified and asked to self-isolate.

"The limited number of areas the student visited last week have been deep cleaned according to DHHS guidelines."

Victorian situation 'evolving rapidly'

Six new coronavirus cases were confirmed in Victoria on Wednesday, bringing the state's total number to 27.

The new cases include six men aged between 30 and 70, who are recovering at home in isolation.

Five of the men had been overseas recently and one is a close contact of a confirmed case.

Westbourne Grammar School has become the latest to close after it was notified a student was being tested for COVID-19.

The school told staff and students to stay home from Friday until Monday.

Principal Meg Hansen said she had been in touch with the Department of Health, which advised her it was not necessary to close the school.

However, Ms Hansen said closing was "purely a precautionary measure".

At a press conference on Thursday afternoon, deputy chief health officer Annaliese van Diemen said eight Grand Prix team members were being tested for coronavirus on Thursday, up from two on Wednesday.

Dr van Diemen said the results were to come through by the end of the day.

Mr Hunt said the Prime Minister had referred all questions from the National Security Committee about people returning from Europe to the medical experts at the Australian Health Protection Principles Committee.

"We will continue to follow their medical advice," he said.

Mr Hunt also said there was no case for major events to be cancelled but that each country and even state had different circumstances.

Victoria's Health Minister Jenny Mikakos, when asked whether the Government was reconsidering letting the F1 go ahead, said "we have been acting on the advice of the chief health officer and the advice to date is there has been no need to cancel mass gathering events".

Ms Mikakos said the cancellation of mass gatherings would happen after Victoria had developed significant community transmissions but at this point, there had not been a single case of unknown community transmission in Australia.

Victoria's chief health officer, Brett Sutton, said the situation was "evolving rapidly".

"For the virus to spread, extended close personal contact is most likely required," he said.

"But visitors to locations where cases have been should be aware of the signs and symptoms of COVID-19."

Close personal contact is at least 15 minutes face-to-face or more than two hours in the same room.

Ms Mikakos said the advice from the chief health officer remained that there was no case against major events continuing.

She said that the Government would not hesitate to take extreme measures such as cancelling major events once there was significant community transmission.

"At this point in time we don't have a single case of unknown community transmission in Victoria," she said.

"We have not reached the point in time where we need to take these extreme measures but we will not hesitate if we get the advice to take those steps."

She said that there was already significant "community intermingling" and compared someone with coronavirus attending the F1 with walking around the CBD.

So far, 5,200 Victorians had received negative tests for coronavirus.

St Vincent's, Peninsula Health, Albury Wodonga, Bass Coast Health and Barwon Health have opened screening clinics taking the state's total number of screening clinics to 12.

"We will be working on opening more and working closely to ensure we can get GP pop up clinics right across Victoria as well," she said.
