Australian Open 2020: How to Watch Serena Williams, Roger Federer, Novak Djokovic First round Matches, Start times, Live Stream

Naomi Osaka, Serena Williams, Roger Federer and Novak Djokovic are all in action in the first round of the Australian Open on Monday, which also sees teenage sensation Coco Gauff facing Venus Williams.

Osaka, the defending champion, has the honor of opening the play at the Rod Laver Arena—the tournament's center court—when she takes on Marie Bouzkova of the Czech Republic at 11 a.m. local time on Monday (7 p.m. ET on Sunday).

Williams and Federer, who begin their quest for an eighth and seventh Australian Open title respectively, are both in action in the next two games at the Rod Laver Arena.

The former faces Russia's Anastasia Potapova, while the latter takes on Steve Johnson of the U.S.

Federer, the world No. 3, also defended his stance on players' health in the wake of the Australian wildfires, suggesting he had done all he could to make the players' voices heard.

Australia has been ravaged by bushfires since September, with over 10.3 million hectares of land destroyed and at least 28 people and an estimated half a billion animals killed.

The blazes have also impacted air quality, which has reached dangerous levels in Melbourne and Sydney and surrounding areas at different stages over the last couple of months.

A number of players struggled to breathe during the qualifying rounds in Melbourne and the quality of air remains a major concern, even though organizers have sought to reassure the tournament will go ahead without major disruptions.

"What can I do? I can go to the office, speak to them [the organizers]," Federer said on Saturday.

"I went to them the first day when it was bad on Tuesday, the next day on Wednesday when it was still bad.

"Can I go on court and say, Everybody stop play? I can try. I don't think that's going to do much."

Meanwhile, Djokovic's bid to defend the title he won 12 months will begin on the same court in the evening, with the Serb due at the Rod Laver Arena following the end of the match between local hero and world No. 1 Ashleigh Barty and Lesia Tsurenko of Ukraine.

Djokovic's first opponent is Germany's Jan-Lennard Struff, the world No. 37.
