This study set out to determine the most important antecedents influencing the decision of players at the top five South African rugby unions to play overseas. A literature review was conducted in order to establish the theory base for the study. A survey, utilizing a self-administered questionnaire, of players at the top five South African rugby unions was conducted to determine the antecedents influencing the migration decision. The study noted financial reasons as the main antecedent in the decision to migrate. Based on players’ opinions, any strategy devised by the rugby unions to address the problem of player migration would have to focus on a number of facets rather than on one single area of concern.
