In 1965 Devaney won a sixth National League medal as New York were narrowly defeated on an aggregate score of 6-19 to 5-20. Tipperary demolished all opposition in the provincial championship once again and a 4-11 to 0-5 trouncing of Cork gave Devaney a sixth Munster medal. Wexford were Tipperary's opponents in the subsequent All-Ireland final on 5 September 1965, however, the game failed to live up to the two classic games between the two sides in 1960 and 1962. Victory went to Tipperary on that occasion by 2-16 to 0-10, courtesy of a brace of goals by Seán McLoughlin. The win gave Devaney a fifth All-Ireland medal.
