Iakovleva was born in Petrozavodsk, Russia, and she began rhythmic gymnastics when she was five years old.[2] She moved with her family to Australia when she was seven years old.[3] She is coached by her mother, Iuliia Iakovleva, at Aspire Gymnastics Academy in Brisbane.[4]
Iakovleva became eligible for senior competition in 2019. She finished 59th in the all-around at the Pesaro World Cup.[7] Then at the World Challenge Cup in Kazan, she finished 47th in the all-around.[8] She was selected to compete at the World Championships in Baku. The Australian team finished 13th, and she finished 65th in the all-around during the qualification round.[9]
2021
Iakovleva competed at the 2021 Oceania Championships in Gold Coast, Queensland, which doubled as the Australian Championships and was an Olympic qualifier. She won the gold medal in the all-around and received the continental berth for the 2020 Olympic Games.[10][11] After this qualification event, hosting organisations and officials were sanctioned for competition manipulations that lead to Iakovleva going to Tokyo; however, upon review by the International Gymnastics Federation the decision was found to be legitimate.[12]
In 2022, Iakovleva was awarded a Tier 3 scholarship for the Sport Australia Hall of Fame Scholarship and Mentoring Program.[15] At the Athens World Cup, she placed 13th in the all-around, and she qualified for the ribbon final where she finished seventh.[16] She then placed 24th in the all-around at the Pesaro World Cup.[17] She finished second in the all-around to Alexandra Kiroi-Bogatyreva at the Australian Championships.[18]
Iakovleva began competing with the Aspire Gymnastics Academy rhythmic gymnastics group in 2023.[21] The group placed fifth in the all-around at the Tashkent World Cup.[22] Additionally, they finished seventh in the 5 hoops final and sixth in the 3 ribbons + 2 balls final.[23] The Aspire group was not selected for the 2023 World Championships, and their appeal to the National Sports Tribunal was dismissed.[24]
