The Australian Open quarantine facilities are still holding 15 people, including one player and two others who tested positive for COVID-19 earlier in their lockdown, Melbourne health authorities said on Sunday.
The vast majority of the more than 1,000 players and their entourages undergoing 14 days of isolation in Melbourne and Adelaide were released by midnight on Saturday and have started preparing for the Grand Slam.
Spain's Paula Badosa was the only player to have confirmed that she tested positive for COVID-19 in Melbourne, restarting the clock on her mandatory period of isolation.
