The measures come into effect from 8pm on 5 August until 11:59 on 12 August 2021.
All gaming, food, retail and conference operations will cease, but hotel accommodations will still be provided.
Crown Melbourne only reopened at the end of July following an earlier five day lockdown imposed by the state of Victoria.
As well as covering employees’ salary for the duration of the lockdown, Crown Resorts has said it will continue to work closely with the Victoria government and health authorities to respond to measures taken in relation to Covid-19.
The impact of the pandemic has been felt by the company, which expects to record full year losses for 2021.
Crown has also faced questions about its operations and its future licence status. After the Bergin Report determined that it was not a suitable licensee in New South Wales, a similar inquiry was opened in Victoria.
