rise primarily originating from breaches in hotel quarantine. On 20 June, with the state recording 25 cases, Andrews mostly delayed the planned easing of restrictions and reinstated stricter home gathering rules. On 30 June, with the state recording 64 new infections, Andrews announced stage 3 restrictions for 10 postcodes within metropolitan Melbourne, suspended international flights and announced a judicial inquiry into the state's hotel quarantine program. Andrews announced a further two postcodes would return to stage 3 restrictions and a 'hard lockdown' of public housing towers in North Melbourne and Kensington on 4 July. The Ombudsman later criticised the timing and conduct of the lockdown as potentially violating the residents' charter rights . On 7 July, Andrews announced the reimposition of stage 3 restrictions for metropolitan Melbourne and Mitchell Shire as the state recorded 191 new cases. Under these restrictions, residents in the affected area could only leave the home for exercise, obtaining supplies, work if it couldn't be done from home and to provide care and compassion. In early August 2020, following a spike in COVID-19 infections in Victoria with up to 750 new infections detected per day, Andrews declared a State of Disaster and announced Stage 4 lockdown rules for 31 metropolitan Melbourne municipalities and Stage 3 rules for regional parts of the state. The Stage 4 rules for Melbourne included compulsory face masks, all but essential businesses closed, residents only being allowed to leave their homes once a day to shop for essential items only, and once a day to exercise for a maximum of one hour. Both these activities were restricted to within five kilometres of home. All schooling was to be done remotely using electronic communication. A nightly curfew from 8 pm to 5 am was introduced. Exemptions existed for workers deemed essential. The restrictions correlated with a reduction in the rate of infections, such that by mid-September 2020 the 14-day case average was 44.4 rather than 63 predicted by the modelling done when they were introduced. Restrictions began to ease from that time. On 26 October 2020, Victoria recorded no new cases and no new deaths, its first day of no cases since early June. The achievement was called "Donut Day". In 2021, further COVID-19 outbreaks in Victoria led to lockdowns being reinstated a further four times, with restrictions including a 9:00 pm–5:00 am curfew and 5 km travel limit reinstated for residents of
