"Terminal 3" marked Ireland's return to Eurovision following RTÉ's decision to opt out of the 1983 contest because of financial constraints.

Radio Telefís Éireann (RTÉ) held the national final on 31 March 1984 at its studios in Dublin, hosted by Gay Byrne.

Contestants included 1981 Irish representatives Sheeba, and Charlie McGettigan,[1] who would go on to win Eurovision ten years down the line.

Pre-contest, "Terminal 3" had been rated as one of the front runners in a field with no obvious stand-out song, and Martin gave a vocally strong and visually striking performance.

[2] "Terminal 3" received four maximum 12s – from Belgium, Italy, Sweden and Switzerland – with only Yugoslavia failing to award it any points at all.
