This thesis examines the play of children in three Melbourne primary school playgrounds, in diverse socio-economic areas. Play categories were developed and data was collected using qualitative methods. The influence of school policy, teacher supervision styles, playspace design and provision of play equipment was explored and compared for each school. The voices of principals, teachers and children, in conjunction with playground observations and questionnaire response were compiled in order to develop a clear picture of each school playground. Findings showed that children in each school participated in a full range of play categories and were prepared to break school rules in order to do so.
