Early life
Gadecki was born and raised on the Gold Coast into a family with a single mother and five brothers.[2][3] She started playing tennis at three years old in Palm Beach on the Gold Coast.[4][1] Gadecki is of Polish descent on both sides of her family.[5] She was considered a prodigious tennis talent as a junior and at the age of 12 was one of just 16 players from around the world invited to take part in the Longines Future Tennis Aces competition in Paris on the eve of the 2014 French Open.[6] Gadecki quit playing tennis shortly afterwards, and was ultimately encouraged by fellow Australian Ash Barty to return to the sport after completing high school. Gadecki attended Southport State High School throughout her teenage years.[7]
Career

Gadecki made her main-draw debut on the ITF Circuit in Brisbane, in September 2016.
In February, Gadecki won her first WTA Tour singles main-draw match at the Phillip Island Trophy.[10] She followed this up with her first top-10 win, defeating the top seed, former Australian Open champion and world No. 4, Sofia Kenin. With Gadecki's career-high ranking being No. 988 in the world, this was Kenin's worst defeat by ranking on the WTA Tour.[11] Gadecki lost in the third round.[12] The following week, she re-entered the WTA rankings at No. 642.[13] In May 2021, Gadecki won her first professional singles title in Turkey.[14]
In August 2021, she won the women's singles and doubles titles at Vigo, Spain. It was her second singles title and fifth doubles title.[15]
On 20 September 2021, Gadecki debuted in the Australian top 10 in singles and doubles rankings.[16] She ended the year with a singles ranking of No. 238.
2024: Olympics in singles & doubles, WTA Tour final, top 100, Australian No. 1
She reached a career-high ranking at world No. 120 on 15 January 2024, prior to the 2024 Australian Open where she received a wildcard for the main draw, losing to Sloane Stephens.[23]
Ranked No. 152, she qualified for the Guadalajara Open and defeated Sloane Stephens in the first round.[27] She then upset second seed Danielle Collins, in straight sets in the second round, to reach her first WTA Tour quarterfinal and first at the 500-level.[28][29] Next, she defeated Martina Trevisan, her third top 100 win, to reach her first WTA Tour semifinal (the third active Australian woman player to reach a semifinal at the WTA 500 level after Ajla Tomljanović and Daria Saville), and finally Camila Osorio to reach her maiden career final.[30][31][32] As a result, she reached a new career-high in the top 90, raising close to 65 positions, becoming the Australian No. 1 ahead of Daria Saville in the women's singles rankings on 16 September 2024.[33][34] She became the first Australian to reach a WTA 500 singles final since Ash Barty in January 2022 in Adelaide.[35][36] Gadecki lost in the final to Magdalena Fręch.[37]
