Australian academic libraries are highly adaptive to the changing needs of learning and teaching and research and the demands of the changing information environment. Liaison Librarians are absolutely central to the academic library's ability to manage change and anticipate and prepare for the future. However little is shared in conference papers and journal publications about how Liaison is organised, developed and supported by academic libraries. Queensland University of Technology (QUT) and University of Tasmania (UTAS) Libraries have explicit, well established and long-running Liaison programs. UTAS recently embarked on a change process to move from an individual, school-focussed model to a faculty-focused, team approach to Liaison organisation. The process led to the organisation of teams, with team-member leadership roles in collection development, learning and teaching, and research support. The new organisation also established a learning environment in which librarians continue to change in a rapidly changing environment. At QUT Library the Workforce Plan has set the framework for the re-examination of the highly Faculty-integrated Liaison model to improve support for the University's research agenda, to respond to the changes in scholarly communication and to work collaboratively with the University's Teaching and Learning Support (TALSS) to embed information and academic literacies into the University's curriculum. This paper examines recent literature on Liaison, discusses two case studies of Liaison organisation at QUT and UTAS Libraries and how these changing models prepare libraries and librarians for the future of university learning and teaching and research and the changing information environment
