Allison joined the Firebirds ahead of the 2025 Suncorp Super Netball season and made an immediate impact, becoming Firebird No.114 when she debuted in last year's season opener against GIANTS Netball.
Across her two seasons in Australia, the midcourter made 26 appearances in the purple dress, quickly establishing herself as a popular and much-loved member of the club both on and off the court.
Beyond her athletic contributions, Allison leaves a lasting legacy through her passionate advocacy work.
She will be fondly remembered for her dedicated service across both seasons as a Netball Queensland LGBTQ+ Elite Athlete Champion, where her commitment to fostering an inclusive and welcoming environment made a meaningful difference to the broader Queensland netball community.
Firebirds Head Coach Kiri Wills expressed her gratitude for Allison's contributions to the club.
"Imogen has been an absolute pleasure to coach and have as part of our Firebirds family," Wills said.
"She brought incredible energy, professionalism, and genuine care to everything she did - both as a player and as a champion for our community.
"While we're sad to see her go, we're excited for this next chapter in her career and wish her nothing but the very best back home in England."
