The specific focus of this study is to explore Queensland (Australia) state school generalist teachers' perceptions regarding the barriers and enablers associated with the implementation of the Smart Moves (compulsory physical activity) policy in the primary classroom setting. This study sought to primarily add to the literature on, and understanding about, implementing compulsory physical activity policy by generalist primary teachers. More generally, this study also aimed to explore generalist primary teachers' attitudes towards daily compulsory physical activity policy within the context of Smart Moves. Such a research undertaking was positioned within the interpretivist paradigm and a basic interpretive study methodology was employed. The research project involved semi-structured interviews with six generalist teachers from six Gold Coast State primary schools. Results of this study identify a cross section of both major thematic institutional and teacher-related barriers and enablers affecting the implementation of the Smart Moves policy. The subthemes being: (1) crowded curriculum, (2) lack of priority, (3) ensured that children are physically active, (4) the importance of teacher confidence and (5) inadequate access to facilities and equipment. These factors are clearly affecting the implementation of Smart Moves sessions and need to be addressed to ensure teacher compliance for the benefit of students. This paper concludes by offering potential recommendations for the future adoption and implementation of compulsory physical activity programmes within a primary school setting.
