Victoria will be plunged into a seven-day lockdown from 11.59pm tonight.

It comes after 12 COVID-19 cases were reported in the 24 hours to midnight last night.

150 exposure sites have now been identifed by Victorian health authorities, which spread across more than 30 Melbourne suburbs and regional centres.

WA Premier Mark McGowan is expected to hold a press conference shortly detailing WA’s response to the growing cluster.
