AFL career
Greater Western Sydney
In March 2018, Cumming recommitted to GWS until 2020.[4] Wearing the number 13,[1] Cumming played 5 games in 2019, but was omitted from the squad for the club's historic finals series in which they made the grand final.[5] In the 2023 preliminary final against Collingwood, Cumming scored a goal to set up a 10-point lead at half time, but the Giants went on to lose by a solitary point.[6] A pre-season calf injury prevented Cumming from playing early in the 2024 season, but returned later and played 6 games for Greater Western Sydney.[7] Following the Giants' semi-final exit in 2024, Cumming informed the club of his desire to exercise his free agency, seeking a move to South Australia.[8]
Adelaide
In September 2024, Cumming announced his desire to join the Adelaide during the free agency period, citing fellow Broken Hill native Taylor Walker as a key influence behind the decision.[9][1] Cumming officially signed with the Crows on 4 October.[10][11]
