These countries, and the seven countries listed above, were invited to send a full delegation to the EUSO 2005. The "third EUSO" was held in Galway, Ireland, on 14–21 May 2005.

The Patron was Mr. Noel Treacy TD, Minister for European Affairs. A constitutional change (3.2.1) in 2004 reduced the delegations to two teams with three science students in each and a Mentor for each discipline (Biology, Chemistry and Physics), with one acting as the Country Coordinator and one acting as the Head of the Delegation. Ten countries were represented by a total of 18 teams (54 Students): Belgium (2 teams), Cyprus (2 teams), Estonia (2 teams), Germany (2 teams), Ireland (2 teams), Latvia (1 team), Netherlands (2 teams), Slovakia (1 team), Spain (2 teams) and Sweden (2 teams).
