Tiana Mangakahia, former Syracuse standout and WNBL player, dies at 30 after cancer battle

Tiana Mangakahia, the Australian guard who rose to prominence at Syracuse University and played professionally in Australia and the United States, died Sept. 11, 2025, at age 30 after a second battle with breast cancer, her family said.

"We are heartbroken to share the passing of our beautiful Tiana Mangakahia," the family wrote on social media. "She left us on 9/11/2025, surrounded by family, friends and lots of love. Tiana was a shining light who touched the lives of everyone she met with her kindness, strength, and warmth. She fought right till the very end, showing courage and grace beyond words. Though our hearts ache without her, her legacy and the love she gave will stay with us forever. We will continue to honour her in everything we do. We love you endlessly, Tiana, and will miss you always. #Tough4T."

Mangakahia first drew wide attention at Syracuse, where her court vision and playmaking earned her national recognition. She was diagnosed with breast cancer in 2019 shortly after being selected for the Australian Opals' Olympic training squad. She underwent chemotherapy, a double mastectomy and reconstructive surgery and returned to competitive play in 2021 while at Syracuse.

Her cancer returned and progressed to stage four in 2023, forcing her to retire on medical grounds. In a sign of her persistence and connection to the game, she made a brief on-court comeback in June 2025 with NBL1 side the Southern Districts Spartans, but announced Sept. 3 that her health had rapidly deteriorated and that she was stepping away again. In a post to supporters at that time, Mangakahia said her condition had taken a "negative turn" over five days and that she was experiencing "significant physical decline," asking for privacy while saying she remained hopeful and grateful for messages and prayers.

The news drew immediate responses from across the basketball community. Australian great Lauren Jackson posted a heartbroken response and "sending love." Fellow Australian Maddie Garrick wrote, "I am lost for words. Sending so much love and support to all those close to you and especially your family. Beautiful soul! Rest peacefully, T." Russian player Yana Kosogortseva wrote, "We will never forget you, T from Russia with love." Other players and figures including Mitch McCarron, Ally Wilson, Josh Giddey and WNBA star Paige Bueckers left messages of support and heart emojis on social posts. Olympic swimmer Jess Fox said, "Sending so much love. Rest in peace Tiana."

Basketball Australia released a statement mourning Mangakahia and praising her courage and resilience. "Tiana inspired us all with her courage and resilience as she faced a second battle with breast cancer," the organization said, noting her return to the NBL1 with the Southern Districts Spartans earlier in the year and her appearance alongside national teams at an Opals vs. Tall Ferns fixture on the Sunshine Coast in May. "Her presence was a reminder of the impact she made on teammates, fans, and the wider basketball community. We were fortunate to have her join us... Forever an Opal."

Mangakahia played in the Women's National Basketball League with the Sydney Flames and appeared at WNBL events, including presenting Pink Hoops MVP awards in 2024. Her professional career also included stints that brought her to the attention of WNBA and international audiences. Teammates, coaches and fans frequently cited her leadership, playmaking and determination both on and off the court.

Friends and family have memorialized Mangakahia's public fight with cancer and her efforts to remain involved in basketball despite serious health setbacks. Her family asked that her legacy be honored through remembrance of her "kindness, strength, and warmth." Tributes continued to pour in on social media and from sporting organizations in the hours after the announcement.

Mangakahia's passing marks a loss for the Australian and international basketball communities, where she was widely admired for returning to competitive play after major surgery and for the visible candor with which she spoke about her illness. Funeral arrangements and further details were not announced by the family as of Friday morning.

Her public battle with cancer, her returns to the court and the outpouring of support underline the impact she had on teammates, opponents and fans during a career curtailed by illness but defined by resilience and leadership.
