The research reported in this paper investigates why teachers in regional primary schools in the Ballarat region of Victoria, Australia, are choosing to outsource the teaching of sexuality education. A survey was conducted of 29 Year 5 and Year 6 teachers from local primary schools. The teachers provided information about: their confidence in delivering sexuality-related topics; their perceptions of the relevance of given sexuality topics to their students; the teachers' own professional development preferences; and what they saw as their personal limitations in teaching sexuality education. Teachers tended to report low confidence in teaching topics that are considered "sensitive", such as menstruation, wet dreams and sexual intercourse. Furthermore, they indicated a need for professional development in teaching sexuality education. The greatest hurdle identified lies in identifying how to motivate, engage and support teachers to take a professional interest in teaching sexuality education. (Contains 3 figures and 1 table.)
