Johnson debuted for Geelong in the opening round of 2022 AFL Women's season 6.[3] On debut, Johnson collected 6 disposals and 3 marks.[4] After stringing together four games, Johnson suffered a foot fracture in the team's round 5 win against West Coast, keeping her out of the team for the remainder of the season.[5][6]
Her 2022 season 7 was a much more successful year. Playing every game, she became an important part of Geelong's backline, making the initial 44 player squad of the 22under22 team at the conclusion of the season.[7]
2023 was a challenging year as Johnson managed just one game before a knee injury ruled her out from Round 2 onwards.
