From Wynyard, Tasmania, Haines grew up playing basketball with her identical twin sister Libby. They were both introduced to football through a clinic administered by the Burnie Dockers at their school Hellyer College when they were in year 10.[1] Both sisters were included in the 2018 AFLW Academy, which allowed them to train with AFLW clubs and attend development camps.[2][3] They played for their state at the 2018 AFL Women's Under 18 Championships and later competed in the Eastern Allies team. Both sisters played in a VFL Women's match for Melbourne University – Chloe amassed 12 disposals, five marks and five tackles.[4]
