Impact of the COVID-19 pandemic

On 17 December 2020, due to mandatory 14-day quarantine on all arrivals into the country Tennis Australia announced that the start of Australian Open would be delayed by three weeks from 18 January 2021 to 8 February. This was to provide time for those who qualify to quarantine before the tournament. For the same reasons, the men's and women's qualifying matches were held outside of the country in Doha and Dubai respectively, and the junior and legends matches were not played.^[6][7]

To honour key workers, recordings of their voices were broadcast for line calls as part of the electronic system.^[5]

On 4 February 2021, all of the scheduled day's events leading up to the tournament, including the ATP Cup and warm-ups, had to be suspended after a 26-year-old man working at the hotel players were quarantining at tested positive for COVID-19. Victorian premier Daniel Andrews stated that the 8 February start would not be affected due to the schedule change. The events originally scheduled for 4 February as well as the draw ceremonies were held the next day.^[8]

The hard quarantine policy was viewed as significantly affecting the tournament bracket, especially in women's singles. In all, 26 players in the women's singles bracket were quarantined, with 12 of them seeded. Nine quarantined players, including four seeds (one of them, past Australian Open winner Angelique Kerber), lost in the first round to players who had not been quarantined. Of the 13 quarantined players who survived the first round, five (including two seeds) lost in the second round, and only 22 seed Jennifer Brady advanced past the third round. While the men's singles draw had more quarantined players (29 in all), the only seeded player among that group was No. 25 Benoît Paire. Six first-round matches were between players in this group; of the other 17 players who had been quarantined (including Paire), only Pablo Cuevas won his first-round match. The six survivors all lost in the second round.^[9]
