Naomi Osaka and Aryna Sabalenka have both withdrawn from the Australian Open due to health concerns. Osaka, who was the top seed in the women's singles draw, cited a "medical issue" as the reason for her withdrawal, while Sabalenka pulled out with an "ankle injury". The withdrawals mean that Coco Gauff will face Liudmila Samsonova in the first round of the women's singles competition.
