He had recently travelled to Wuhan - the epicentre of the outbreak - and became unwell two days after returning.

The Department of Health and Human Services says there is no evidence passengers or crew on board the flight to Melbourne are at risk of contracting the virus.

The man was treated by doctors at the Monash Medical Centre and was assessed as being well enough to stay at home - where he is currently in isolation.

Health officials are now closely monitoring five people he had close contact with, including two children.

The man also ate at a restaurant in Glen Waverly - The House of Delight - on Australia Day.

Health officials are contacting diners who ate there at the same time.

The confirmation brings the national total of cases to six, four in New South Wales and two in Victoria.
