Gill first came to prominence on the inter-county scene as a member of the Galway senior hurling team in 1922. That year he made his championship debut at right wing-back in the All-Ireland semi-final against Tipperary. The game itself wasn’t played until 26 August 1923 and Gill ended up on the losing side that day. His next outing with Galway was in the 1923 All-Ireland semi-final against the reigning champions Kilkenny. Once again the game was delayed and wasn’t played until 18 May 1924, however, this time Gill's team beat the champions against all the odds. Galway were later awarded the All-Ireland title as Limerick refused to play until all Civil War prisoners were released and were initially disqualified. The game was eventually played on 14 September 1924. Gill made a huge contribution at midfield and his ploy of lobbing the ball into the square resulted in a 7-3 to 4-5 victory for Galway. Gill was one of the most effective members of the team and richly deserved his All-Ireland medal.
