Early Career
Born and raised on the Gold Coast, Queensland, Olivia Gadecki was a prodigious talent from a young age. She picked up a racquet at three years old, encouraged by her brothers, and quickly rose through the Australian junior ranks.
Her potential was recognized globally when she was selected as one of only 16 players worldwide to compete in the Longines Future Tennis Aces tournament in Paris at age 12.
Despite her early promise, Gadecki took a break from the sport during her teenage years to focus on her schooling at Southport State High School. It was former world No. 1 Ashleigh Barty who played a pivotal role in her return to professional tennis.
Barty mentored the young Queenslander, encouraging her to pursue a pro career. This mentorship proved crucial, as Gadecki made a stunning professional debut in 2021.
In one of her first major matches, she defeated then-world No. 4 Sofia Kenin at the Phillip Island Trophy, signaling her arrival on the world stage as a teenager with immense firepower.
Professional Career
Gadecki’s transition to the main tour was marked by steady progression and significant milestones. After grinding through the ITF circuit to build her ranking, she began making waves at the WTA level in 2023 and 2024.
She reached her first WTA singles final at the Guadalajara Open in 2024, a WTA 500 event, where she defeated high-caliber opponents like Sloane Stephens and Danielle Collins.
This run propelled her into the top 100 for the first time, peaking at a career-high ranking of No. 83 in singles.

Throughout 2025, she continued to compete at the highest level, making deep runs in doubles tournaments, including a semifinal appearance at Wimbledon alongside Desirae Krawczyk. Her aggressive baseline game and improved consistency have made her a formidable opponent on all surfaces.

Under Sears’ guidance, Gadecki has refined her tactical understanding of the game and improved her mental resilience in big matches.
