A second week of lockdown looms for 6.5million Victorians amid growing concern from authorities that the latest coronavirus outbreak is spreading rapidly between complete strangers.
The highly infectious outbreak grew to 54 cases on Tuesday, including nine new locally-acquired cases and two in hotel quarantine.
Six of those local infections had been confirmed a day earlier.
