Young people's "sexting"--defined by the "Macquarie Dictionary Online" (2010) as the sending and receiving of sexually explicit images via mobile phones--has become a focus of much media reporting; however, research regarding the phenomenon is in its infancy. This paper reports on the first phase of a study to understand this activity more comprehensively. Interviews were conducted with notable key informants (including teen culture authors and professionals from the academic, education and health sectors) to create a context for a second phase involving interviews with young people. Insights were offered into reasons for young people's participation, potential consequences and solutions. Highlighted was a gap in reliable data from the perspective of young people themselves, and the importance of their voice in understanding and developing effective strategies to prevent and deal with this phenomenon.
