Victoria has recorded its first COVID infection in hotel quarantine since the state again started accepting international flights.
The new case is an international passenger who arrived in Melbourne on a flight from Doha on Thursday.
COVID-19 Quarantine Victoria (CQV), the government unit that runs the hotel quarantine program, said the person was a man in his 40s.
He returned a positive test result yesterday and was transferred to a health hotel last night, CQV said.
Health hotels are quarantine hotels set up specifically to hold people who test positive to the virus.
No new COVID infections were recorded in the community yesterday, taking Victoria's streak of no locally-acquired cases to 43 days.
The new case is the first one recorded in an overseas arrival since international flights started arriving in Melbourne again on Thursday.
The hotel quarantine program was shut down and overhauled in mid-February after the virus leaked out from a hotel and sparked a five-day lockdown.
Measures introduced in this overhaul include only rostering on hotel quarantine staff who have had at least the first COVID vaccine dose, and doubling the number of times arrivals get tested during their stay.
Previously, international arrivals were only tested for COVID twice during their two weeks in quarantine, but they will now be tested upon entering the program and on days four, 12 and 14.
Staff who work in the program are tested daily on shift, and encouraged to get tested on their days off.
More than 2,800 hotel quarantine staff members have also undergone N95 mask fit-testing and refresher training.
"CQV has strict IPC [infection prevention and control] processes and procedures, daily staff testing and workers are N95 mask fit test and trained and well prepared to manage positive cases," a CQV spokesperson said in a statement.
Data on the Victorian government website says 104 overseas arrivals are expected to land in the state today.
Yesterday, 4,810 vaccine doses were administered in Victoria, taking the total of jabs delivered in the state to 142,130.
