In 2004, the Australian National Rugby League (NRL) commissioned the Playing By The Rules research project in response to allegations of sexual assault by members of a professional rugby league team. This article offers an overview of the theoretical and methodological approaches adopted by the team, and the subsequent workplace education programmes designed to promote ethical sexual behaviour and attitudes within NRL culture. The researchers reflect on contemporary thinking in the relatively new field of violence prevention education aimed at young men, and consider new critical approaches to the intersection of masculinities and sexual learning.
