The man who arrived from America had permission to travel to Melbourne under the exemption scheme to see a family member in palliative care. He had received a negative test at Sydney airport before flying to Tullamarine, but still should have gone directly into hotel quarantine, which was at the time taking travellers with exemptions and Melbourne people unable to quarantine at home.
However, he was not greeted at the airport by a government official and taken to a hotel. A state government spokeswoman has confirmed that officials did not have his flight details, so they were unaware of his arrival.
