Through a nationwide survey of universities and research organizations in Australia and New Zealand, this article investigates the level of confidence that librarians working in scholarly communication have in their current competencies. The results show that while respondents were generally confident across seven competency areas (Institutional repository management, Publishing services, Research practice, Copyright services, Open access policies and scholarly communication landscape, Data management services, and Assessment and impact metrics), the majority combined their scholarly communication tasks with other roles. Challenges across the sector in updating skills and knowledge to keep abreast of current trends and developments were identified, with implications for improving professional development opportunities.
