One fundamental aspect of organizational transformation in higher education is the change to the profile of universities' non-academic workforce. Key staffing trends identified in recent studies conducted in a variety of national settings include an increase in the proportion of non-academic staff at universities and a shift toward more highly qualified and remunerated non-academic roles. This paper examines the extent to which these trends have played out at Australian universities over the period 1997 to 2017. Drawing on unpublished sets of staffing data, the analyses show that while the proportion of non-academic positions at Australian universities has remained largely stable, there has been a striking and uniform growth in management-rank positions, concurrent with a substantial decline in lower-level and less expensive support roles. This has some significant implications, in particular the growth in more complex "corporate" structures, the relatively fewer staff to support academic work, and the increase in the relative costs associated with maintaining the non-academic workforce at Australian universities.
