Millea first played hurling and Gaelic football at club level with Graigue. He was part of the Graigue team that won junior divisional football honours in 1960, before ending the year with a Kilkenny JFC medal after a defeat of St Nicholas's in the final. A decade later Millea, by now playing with the Graigue-Ballycallan amalgamation, added a North Kilkenny JHC medal to his collection.[2]
Millea joined the Kilkenny senior hurling team in advance of the 1969 season and quickly won a Leinster SHC medal. He later scored a goal in Kilkenny's defeat of Cork in the 1969 All-Ireland final.[3] Millea lined out in a second Leinster final without success in 1970.[4] He was called up to the Leinster inter-provincial team in 1971 and won a Railway Cup medal that year after a defeat of Munster in the final.
In retirement from playing, Millea became involved in the coaching and administrative affairs of the Graigue-Ballycallan club.
Personal life and death
Millea built a successful business in land reclamation over several years. His daughters, Sinéad and Tracy, played camogie with Kilkenny and were All-Ireland SCC winners.[5][6]
