Emma-Sue Greentree

Before boxing, Greentree was a talented heptathlete who competed nationally throughout her junior years, winning medals at national championships. She was a national heptathlon champion at age 16 and was part of the athletics program at Hunter Sports High School.^[2]

Her athletics career ended when she ruptured her posterior cruciate ligament (PCL) while playing rugby in year 11 (2017). Unable to return to her previous performance levels in athletics, she decided to pursue a new sport.

Greentree began boxing in 2017. She was introduced to the sport through a family connection with Steve Mannix of Central Coast Boxing at Budgewoi, where her father had worked and her brother Daniel also trained.

Greentree's major international breakthrough came at the 2023 World Amateur Boxing Championships in New Delhi, India, where she won bronze in the light-heavyweight division (81 kg).^[1] In the semi-final, she was defeated by India's Saweety Boora on a split decision (4–3), with Boora subsequently winning the gold medal.

In September 2024, Greentree made her professional boxing debut, defeating Stephanie Mfongwot in a six-round contest, winning every round. This victory placed her at #3 in the light-heavyweight rankings on BoxRec.^[3]

Greentree was selected for the Australian team for the 2025 World Boxing Championships in Liverpool, England.^[4]

Greentree is an advocate for athletes with Type 1 diabetes. She manages her condition using a continuous glucose monitor (CGM) that tracks her blood sugar levels and sends data to her phone. She follows a strict diet with support from a dietician who is part of her sponsorship team.^[1]

Outside of boxing, Greentree works as a Special and Inclusive Education Teacher's Aide (SLSO) on the Central Coast, where she supports students in the special education unit.^[5]
