Having played both codes at every grade, he was a forward on both of the college's senior teams that lost the Harty Cup and Corn Uí Mhuirí finals in 2015.
Lining out at full-forward, he ended the game with a second successive winners' medal after scoring four points from play in the 0-18 to 2-11 defeat of the Institute of Technology, Carlow.
A dual player with both the hurlers and Gaelic footballers, his season ultimately ended without success with defeats by Limerick and Dublin.
After playing in the early rounds of both championships, he sustained a broken fibula and significant ligament damage in a challenge game against Clare, bringing his season to an end.
On 4 July 2018, Kingston won a Munster medal after scoring four points from play in Cork's 2-23 to 1-13 defeat of Tipperary in the final.
Kingston made his senior debut for Cork on 2 July 2016, replacing Séamus Harnedy for the final 7 minutes of an All-Ireland Qualifier against Dublin at Páirc Uí Rinn.
