Having played hurling in every grade of hurling during his time at the school, he usually lined out in the half-back line on the school's senior team. On 14 October 2015, Hennessy was at right wing-back on the CBC team that recorded a first victory in the Dr Harty Cup in 97 years.

St Finbarr's
Hennessy joined the St Finbarr's club at a young age and played in all grades at juvenile and underage levels as a dual player of hurling and Gaelic football.

On 28 September 2015, Hennessy was at full-back when the St Finbarr's minor football team defeated Douglas by 1-09 to 0-08 in the final to win a fifth Premier 1 MFC title in nine years.

Hennessy subsequently progressed onto the St Finbarr's under-21 football team. On 6 August 2016, he was at left corner-back on the under-21 team that defeated Ilen Rovers by 1-12 to 0-07 to win the Cork Under-21 Championship title.

Minor and under-21
Hennessy first played for Cork at minor level during the 2015 Munster Championship. He made his only appearance in the grade on 2 July when he came on as a 53rd-minute substitute for John Looney in a 1-14 to 0-14 defeat by Limerick.

Hennessy won a Munster Championship medal on 4 July 2018 when he lined out at right wing-back in Cork's 2-23 to 1-13 defeat of Tipperary in the final.
