In June 2022, both Kelly sisters left the Eagles; Niamh was traded to Adelaide, while Grace departed for St Kilda.[7]
Kelly had a career-best year in 2023. After winning the second-ever Showdown Medal awarded in the AFLW in round one of the season, Kelly recorded a personal-best 28 disposals and 99 AFL Fantasy points in round 8 against Brisbane. The following week, Kelly scored a match-winning goal against an in-form North Melbourne to secure her team a top-two finish and a home qualifying final.[8]
Kelly was rewarded for her outstanding form in 2023 with selection in the All Australian squad.
