International field placements have become increasingly common in Australian social work programmes. This article looks at the models of organising international placements, in sending or receiving social work students. Four such models are identified: informal linkages for individual students, linkages between Australian social work programmes, formalised university to university agreements and formalised university to agency agreements. Although there appears to be a preference for formalised ongoing relationships between institutions in different countries, drawing on all four models as appropriate and feasible will enable everyone involved in international placements to achieve the most positive practice possible.
