Restrictions will come into effect on Tuesday, 27 April and last until Saturday, 1 May.
Crown specified that no gaming activity, theatre or in-house food service will take place.
Hotel and ancillary services, such as takeaway dining, will continue in a limited capacity.
According to reports, the lockdown was announced after a man in the state contracted Coronavirus in hotel quarantine and entered the community while still infectious.
Although restrictions on restaurants, pubs and cafés have been lifted, gyms, nightclubs and casinos must remain closed.
In March Crown increased activity at its Melbourne location after the Victoria state government eased its Coronavirus restrictions.
In February state authorities launched an investigation into Crown Melbourne’s suitability to hold a casino licence following the Bergin inquiry and subsequent report into its New South Wales licence. A similar review then commenced for its suitability to hold a licence for the Perth location.
The report, which was launched to assess Crown’s suitability for a new casino at Barangaroo in Sydney, found evidence to suggest money laundering and associations with organised crime activity.
Also in March, private equity group Blackstone put in a bid to acquire Crown for AUS$8.02bn (£4.47bn/€5.21bn).
