Serena Williams praises 'super intense' Australian Open coronavirus quarantine rules

Seven-time Australian Open singles champion Serena Williams has backed Tennis Australia's quarantine rules ahead of the season-opening major amid criticism of the arrangements from other players. Williams has been quarantining in Adelaide, as have the likes of Rafael Nadal and Novak Djokovic, and has been spared the hard 14-day lockdown that has affected 72 players who arrived in Melbourne almost a fortnight ago. Several players based in Melbourne have publicly voiced their frustration about being confined to their rooms after passengers on the charter flights that carried them to Australia tested positive for COVID-19.
