She made her Grand Slam debut at the 2024 Australian Open,^[6]^[7] and recorded her first win at the WTA 1000 level at the 2024 Dubai Tennis Championships as a wildcard following the retirement of Paula Badosa.

In March 2024 Sun announced her intention to play under the New Zealand flag as part of the New Zealand team for the 2024 Billie Jean King Cup.^[8]
