* Victorian health authorities strongly suspect a Melbourne man picked up COVID-19 during his two weeks in South Australian hotel quarantine.

* The man in his 30s flew into Adelaide from India via the Maldives and Singapore on April 19 before Australia's flight ban came into effect.

* After returning three negative tests in Adelaide hotel quarantine, he returned to his home in Wollert last week and developed symptoms on Saturday before testing positive on Tuesday.

* South Australian authorities are examining whether the man caught the virus before he entered SA and simply had an unusually long incubation period, or caught it from a person with the virus in the room next door at the Playford Hotel.

* Victoria's Chief Health Officer Brett Sutton believes the man caught the virus in the hotel, not in India or on his international flights.

* All three of his household contacts have returned negative test results and authorities have identified seven initial exposure sites across Melbourne.

* Staff at Australia's largest pathology lab software provider evacuated their Melbourne office on Tuesday morning due to the case.

* Victoria Police officers have been put into isolation after rescuing a man believed to have jumped from an oil tanker in Melbourne.

* Prime Minister Scott Morrison marvelled at regional communities emerging from coronavirus restrictions after travelling across the country.

* Treasurer Josh Frydenberg, who wore a tie decorated with tiny aeroplanes to parliament on budget day, remains coy on a reopening date for Australia's international border.

* Opposition Leader Anthony Albanese said tourism operators and universities reliant on international students deserved clear answers on border closures.
