The current development of national curriculum in Australia provides significant opportunities and challenges for the country's 1700 Catholic schools. This article considers the growing interest in the nature of Catholic curriculum from an Australian perspective, at a time of national debate about curriculum. It also offers a case study of the development and implementation of the Diocese of Broken Bay Catholic Worldview statement as an example of a contextualised Catholic curriculum theology. The Catholic Worldview statement includes 10 propositions which reflect the hierarchy of truths central in Catholic teaching. From these, a set of associated values have been identified. The focus of the project is not on what it means to be Catholic in a generalised sense, but on an approach to Catholic curriculum in the context of a particular diocese, in a particular culture, and at a particular time. However, it may serve as a model and inspiration for other contexts.
