She won gold medals in the women's doubles at the 2014 Asian Games, at the 2019 SEA Games and at the 2020 Summer Olympics. She also won three bronze medals at the World Championships in 2015, 2018, and 2019. Polii is a member of BWF Athletes' Commission to represent the needs and views of athletes to the BWF council and committees from 2013 to 2017 and 2021 to 2025.

Having started her career at the Jaya Raya in Jakarta, she later was selected to join the national team in 2003. Polii represented her country in the 2012, 2016 and at the 2020 Summer Olympics. She also featured in the Indonesian women's winning team at the 2007 SEA Games. She reached a career high of world number 2 in the BWF women's doubles rankings alongside Nitya Krishinda Maheswari.

Polii's achievements began when she was paired with Jo Novita, winning a Grand Prix title, two silver medals at the SEA Games in 2005 and 2007, and a bronze in the 2005 Asian Championships. Together with Maheswari, she collected 2 Superseries titles, 3 Grand Prix titles, a gold at the 2014 Asian Games, a silver at the 2013 SEA Games, and bronze medals at the 2015 World and 2016 Asian Championships. She made a new partnership with the youngster Apriyani Rahayu in 2017. Together with Rahayu, she won her first women's doubles gold at the SEA Games in 2019, her first title on home soil at the 2020 Indonesia Masters, and Indonesia's first ever women's doubles gold at the 2020 Summer Olympics.

Early life Greysia Polii was born in Jakarta to Willy Polii and Evie Pakasi, both of Minahasa descent native to North Sulawesi. She is the third of five siblings. She lived in Jakarta until her dad died when she was only 2, and moved to Manado, where she spent her childhood. She was influenced to play badminton by her sister, and by former national player Deyana Lomban. She also idolized Susi Susanti and Zhang Ning. Her talent was already apparent by the time she was six years old. Recognizing her talent, she and her mother moved back to Jakarta in 1995 for better training and a chance to develop her career as a badminton player. Polii decided to join the Jaya Raya Jakarta club.

At the club, her coach Retno Kustijah noticed her talent as a doubles player, and thus, when Polii was 14, she made the decision to switch from singles to doubles. She made it to the national team in 2003.

Polii's given name, Greysia, was created by combining the word "grey," referencing her father's grey hair at the time of her birth, with the last syllable of "Indonesia."

Her late older brother was named Rickettsia Polii, presumably inspired by the genus of bacteria Rickettsia. Combined with the surname Polii, the full name bears resemblance to a scientific Latin binomial name.

Partnered with Heni Budiman, she reached the semi-final stage in the 2003's Malaysia Satellite tournament. As a national team player, she won her first National Championships title with Budiman.

In Switzerland, Polii also finished as the finalist in the mixed doubles with Muhammad Rijal. In June, she helped Indonesia finish second to China in the Sudirman Cup.
