Numerous reports over recent years emphasise the importance of teamwork training in undergraduate programs in environment education at tertiary level. This paper describes a project undertaken by a team of final year undergraduate environment students from four faculties at RMIT University in Australia working on a multi-disciplinary environment project in Vietnam. The students clearly gained confidence in teamwork and working as professionals. Importantly, they identified some of the key issues associated with teamwork, and with professional activities. While they had not yet entered professional work, the students demonstrated that they had learnt skills that would be of direct importance to them in the professional conduct of a multi-disciplinary project. The project also demonstrated that multi-disciplinary teamwork fits well into environmental projects, and importantly that the experiences are recognised by students as being valuable preparation for their environmental professions.
