The 20-year-old, 183cm talent, who is equally comfortable at goal attack or goal shooter, arrives in Brisbane after making her mark with the Melbourne Vixens, where she was part of the club's 2025 championship-winning squad.
Graham made her Super Netball debut in 2024, the same year she earned her first call-up to the Australian 21 and Under squad, and continued building her senior credentials throughout the 2026 season, featuring in eight matches for the Vixens and scoring 26 goals, including 12 Super Shots.
Graham arrives in Queensland following an outstanding underage career that highlights her talent and promise.
In 2025, Graham helped guide Australia to gold at the 21 and Under World Youth Cup in Gibraltar and was named Player of the Tournament for her efforts, the standout moment in a rapid rise through the national pathway that also included selection in the Australian 19 and Under squad in 2023, and the Australian 17 and Under and Pathways (PacificAus Series) squads in 2022.
"I am super grateful and excited to join the Firebirds next season," Graham said.
"I can’t wait to work with some amazing players and be taught under the experience of Kiri.
"I am very keen to get started."
Firebirds Head Coach Kiri Wills said Graham's signing added exciting depth and versatility to the club's shooting stocks.
“Lily is one of the most exciting young shooters in Australia and we're thrilled to bring her into the Purple Family,” Wills said.
“Her ability to play both positions in the shooting circle, her fearlessness with the Super Shot, and the composure she's already shown on the big stage at World Youth Cup level make her a fantastic long-term prospect for this club.
“We are excited to be a part of her journey and can’t wait to start working with her.”
