The focus will be back on Nick Kyrgios during his second-round match against Gilles Simon.
Will he keep up his recent model behavior, or return to some of the prior antics that have left him under the threat of suspension?
Kyrgios, deeply affected by the wildfires that have affected parts of Australia in the past two months, including his hometown of Canberra, has been instrumental in fundraising efforts for the victims. He's also been emotional at times about the devastation.
Asked after his first-round win if he feels like he's better able to focus when he's playing for an extra cause, his answer was easy: "Yeah, for sure. I guess it's just a perspective thing, isn't it? Why am I really getting mad on the tennis court with everything going on? Every match I've played this year, I've been pretty good. It's probably because of everything going on."
Top-ranked Rafael Nadal will be aiming to advance to the third round when he plays Federico Delbonis. Fourth-seeded Daniil Medvedev plays Petro Martinez and seventh-seeded Alexander Zverev takes on Egor Gerasimov. In women's featured matches, No. 2 Karolina Pliskova plays Laura Siegemund, Wimbledon champion Simona Halep plays qualifier Harriet Dart and sixth-seeded Belinda Bencic takes on 2017 French Open champion Jelena Ostapenko.
