The pandemic-induced suspension of international study tours in 2020 permits space within which to examine the specific role of the study tour supervisor and student learning. While there is a significant body of literature on student experiences, relatively little attention has been devoted to the supervisor's role. Drawing on a first-hand account by a nurse educator on Australia's New Colombo Plan (NCP) international study tour program, this paper reveals the role's shifting complexities and uncertainties. This discussion provides the basis from which to explore the dynamics of supervisor-student relationships within unfamiliar overseas settings. The original Grand Tour, particularly the advice provided by Sir Francis Bacon in the early 17th century, serves as a frame of reference against which to evaluate the experiences shared by supervisors and students on international study tours. The frequently hazardous situations they face together required them to assume increasing responsibilities. The paper assesses the strategic and theoretical implications arising from this exercise of responsibility, which is grounded in nursing ethics and the goals of public health.
