PREMIER Daniel Andrews says half of the COVID-19 cases added to the state's tally could be removed once follow-up testing is completed.
He used his daily media conference to share details of all four cases, none of which were recorded in regional Victoria.

Health officials are investigating the origins of the other two cases.
