Victoria's chief health officer Brett Sutton has revealed that the state has confirmed its second case of coronavirus.
Mr Sutton said the second case was a Victorian resident aged in his 60s who became unwell on January 23.
The man had travelled to Wuhan City in Hubei Province and first became unwell more than two days after returning to Australia.
The man went to his general practitioner and was tested and was then referred to the Monash Medical Centre where he was tested again.
Dr Sutton said the man had since returned home, where he was in isolation.
The man's family is in isolation and undergoing ongoing monitoring.
While some have exhibited symptoms, none have returned a positive test yet.
Two of the family members are children who have been excluded from school.
"The man was mostly at home and had isolated himself when unwell but he had gone out to a restaurant called The House of Delight for a short period of time," Dr Sutton said.
The man attended the Glen Waverley restaurant between 5:30pm and 7:00pm on Sunday.
"That restaurant has been followed up with and those who were there at the same time, whose contact details we have, we are following up with," Dr Sutton said.
"But obviously that restaurant is OK to go to now. People don't need to avoid that area or indeed anywhere else people have been, even if infectious at the time."
Anyone who was at the restaurant at the time should be aware of symptoms, and contact 1300 651 160 for advice.
Victoria recorded its first case of the novel coronavirus on Saturday.
That case, a man in his 50s, remains in isolation in the Monash Medical Centre in a stable condition.
The latest diagnosis brings the total number of confirmed coronavirus cases in Australia to six: four in New South Wales, and two in Victoria.
Dr Sutton said the results of tests on 14 more Victorians were still pending while 61 people who were initiallysuspected of having the virus had come back with negative tests.
He said the total number of people coming to Australia who had recently been to Wuhan was unclear.
"We can't know for sure those individuals who might have started their journey in Wuhan," he said.
"We will only know the number of people who are on flights from China on a daily basis."
A Health Department media release said there was no current evidence that passengers or crew on the flight that the man took to return to Melbourne are at risk.
Victorians and visitors returning from Hubei Province or other locations in China with cases have been advised to closely monitor their health.
Anyone who develops symptoms of fever and breathing difficulty or cough within 14 days of travel to Hubei Province or who has had contact with a confirmed case should seek medical help immediately, providing information about their travel history.
More to come.
