Kimberly Birrell is an Australian professional tennis player who made a significant impact as a 17-year-old during the 2016 Australian summer of tennis.

After reaching her first WTA Tour final at the Hobart International on the doubles court at 17, Kim was rewarded with a wildcard into the Australian Open main draw in both singles and doubles. Following this breakthrough, Kim was called up to the Australian Fed Cup team, becoming the 48th woman to represent Australia in this prestigious competition.

In 2019, Kim made significant strides during the Australian summer of tennis, claiming her maiden top-10 win against Daria Kasatkina at the Brisbane International. Her performance earned her a wildcard into the Australian Open, where she advanced to the third round with notable victories over Paula Badosa and Donna Vekic.

Injuries sidelined Kim for the majority of the 2020 and 2021 seasons, but she made a strong return to the WTA tour in 2022. Kim's comeback was highlighted by her performance in the 2023 Australian summer of tennis, where she reached the second round of the Australian Open and broke into the top 150 in the rankings for the first time.

Kim's consistent performances throughout the 2023 season paid off when she broke into the top 100 in the WTA singles rankings for the first time in September, marking a significant milestone in her career.
