In the last decade there has been a shift in the discourses around professional staff in higher education that has been influenced by neoliberal agenda that focused on driving education reforms. Earlier discussions centring around nomenclature variations have progressed to those about creating and developing borderless professionals operating in the third space--a notional space where professional staff and academic staff with diverse and valuable skills work as equal professional partners on complex and multifaceted projects. This article looks at the evolution of the debates around professional staff. It considers how the notions of professionalism and professionalisation are being reconceptualised in the third space. Discussion progresses towards capability building and developmental opportunities of aspiring third space professional staff in higher education settings. Possible pathways of engaging with and empowering professional staff in designing their future careers and professional identities are considered. Building a community of research practices under the auspices of the Association for Tertiary Education Management (ATEM) and engaging postgraduate students in the university third space project work are proposed as potential areas for further research in the field of professional staff capability building.
