1984 was a special year in the annals of Gaelic games as it was the centenary year of the Gaelic Athletic Association. The year began well with Barry-Murphy helping his team to victory in the special Centenary Cup competition. An eight Munster winners' medal soon followed for him as Cork defeated Tipperary by 4–15 to 3–14 in a memorable Munster final. The subsequent All-Ireland final, played at Semple Stadium in Thurles, saw Cork take on Offaly for the first time ever in championship history. The centenary-year final failed to live up to expectations and Cork recorded a relatively easy 3–16 to 1–12 victory with Barry-Murphy winning his fourth All-Ireland winners' medal.
