The purpose of the article is to discuss, explore and advocate for the importance of self-management skills (cognitive and behavioural) for physical activity in health and physical education (HPE) in relation to the newly revised Australian Curriculum. This conceptual paper is presented as two halves. The first half presents an examination of the contemporary literature around learning about physical activity and fitness knowledge (PAFK). In doing so, I present the importance of physical activity and the role of school physical education in the development of cognitive and behavioural skills and the contribution these can make to HPE curriculum and pedagogy. The second half explores and interrogates the proposed sub-strand "Making Active Choices" of version 9.0 of the Australian Curriculum: Health and Physical Education (AC: HPE). Here, I explore the literature as well as the proposed aims, rationale, content descriptions/elaborations and focus areas to ask questions of the legitimacy and value of PAFK and the role of self-management skills in contemporary curriculum policy. The contribution is timely, given the imminent development of the revised AC: HPE and its implications on curriculum and pedagogical enactment in primary and secondary schools here in Australia.
