Dominici had a fine try-scoring record and grabbed four during the 2003 Rugby World Cup, but he had a nightmare of a moment in the 2004 Six Nations Championship against Italy when, having crossed the try-line, he dropped the ball when trying to put it down with one hand. However, France had still gone on to win the game 250. He started all five of Les Bleus' 2005 RBS Six Nations games.
