Olivia Gadecki

Olivia Gadecki (; born 24 April 2002) is an Australian professional tennis player. She has a career-high singles ranking by the WTA of No. 83, achieved on 7 October 2024, and a best doubles ranking of No. 52, reached on 8 December 2025. She won two mixed doubles titles in the 2025 and 2026 editions of the Australian Open with compatriot John Peers.

Early life Gadecki was born and raised on the Gold Coast into a family with a single mother and five brothers. She started playing tennis at three years old in Palm Beach on the Gold Coast. 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. 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.

Career 2016–2020: First steps 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. 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. Gadecki lost in the third round. The following week, she re-entered the WTA rankings at No. 642. In May 2021, Gadecki won her first professional singles title in Turkey.

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.

On 20 September 2021, Gadecki debuted in the Australian top 10 in singles and doubles rankings. She ended the year with a singles ranking of No. 238.

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.
