A member of the AFL Women's Academy, Allen is a medium defender/midfielder with neat skills and excellent decision-making. A strong leader, she captained Vic Country in the 2018 Under-18 Championships. Allen impressed down back in her debut season. She also made the move forward, booting her first AFLW goal against Carlton in Round 5 of the 2019 season. The 18-year-old was awarded a Rising Star nomination after an oustanding performance in the Pies' Round 7 victory over the Brisbane Lions at Victoria Park in 2019.
