The Muslim minority in Papua New Guinea (PNG) has grown by over 500% since 2001 through increased conversions to Islam by indigenous people, and not as a result of increased immigration by Muslims from overseas. The growing Muslim minority population and international events over the last decade have exacerbated tensions in Christian–Muslim relations in PNG. The basis for a further deterioration of interfaith relations exists because a majority of converts embrace Islam due to their desire to resist or reject the influence of Christianity, a religion closely associated with colonization and the destruction of traditional religions and culture. This article examines the resistance to and rejection of Christianity as an aspect of Islamic conversions in PNG by drawing on fieldwork data collected since 2007 among PNG's growing Muslim community to evaluate Christian–Muslim relations.
