In spite of research demonstrating conceptual weakness in many child sexual abuse (CSA) prevention programmes and outdated modes of delivery, students continue to participate in a diversity of initiatives. Referring to the development of a games-based approach to CSA prevention in Australia, this paper examines empirically based attributes of effective CSA prevention programmes for schools including contemporary pedagogies for learning. The paper draws on findings to inform the conceptual development phase of Orbit, an online, free and equal-access, games-based educational approach to CSA prevention for children aged 8-10 years. First, the paper provides a review of CSA prevention in schools and games-based approaches to key learnings in prevention. Second, an overview of Orbit (the Feeling Safe sexual abuse prevention project) is provided. Finally, implications for the development of games-based prevention programmes are offered and an argument is made for the advancement of games-based prevention resources.
