Swiatek will face No. 19 Madison Keys of the U.S. on Thursday night for a berth in the final. The other women’s semifinal is No. 1 Aryna Sabalenka, the two-time defending champion, against her good friend, No. 11 Paula Badosa.

While Sinner will take on Rune, the other matches will see Italy's L. Sonego take on L. Tien who managed to get past Medvedev on his way here.

Jannik Sinner and Iga Swiatek were both subject to doping cases last year, which has overshadowed their participation at the Australian Open.
