Button was drafted by Adelaide with their sixth selection and fifty-third overall in the 2018 AFL Women's draft. Adelaide's GM of Football Administration, Phil Harper, said about her that "She has serious speed and can run and carry the ball on a wing or win it in the contest. Hannah is keen to learn and has a lot of upside as someone relatively new to the game." She made her debut in the one point loss to the at Norwood Oval in the opening round of the 2019 season. She helped Adelaide win the 2019 premiership, missing only one game during the season. After picking up an anterior cruciate ligament injury playing for NT Thunder in the VFL Women's (VFLW), Button was placed on the inactive list for the 2020 season. Due to the timing of her injury, Adelaide were compensated with an extra draft pick in the 2019 AFL Women's draft.
