The devastating Australian wildfires affected the 2020 Australian Open qualifiers when Dalila Jakupovic retired from her match against Stefanie Voegele because of a coughing fit, according to Leo Schlink and Lauren Wood of the Herald Sun.

"The right-hander complained of breathing difficulties in the first set," Schlink and Wood added. "Jakupovic was treated by medical staff on several occasions before deciding to retire."

Jakupovic was leading the match 6-4, 5-6.
