This chapter explores the critical role of organisational culture in promoting good governance within the South African military. Drawing on the symbiotic relationship between leadership and organisational culture, it highlights how governance frameworks such as the King Reports and the South African Constitution provide foundational principles of accountability, transparency, and ethical leadership. The discussion situates good governance within international, African, and South African contexts, and underscores that organisational culture acts as both a moderator of behaviour and a determinant of governance outcomes. It identifies persistent challenges in the SANDF, including punitive and bureaucratic cultures, weak value systems, and limited buy-in from members, which undermines effective governance. Ultimately, the chapter argues that fostering a conducive organisational culture rooted in integrity, accountability, and inclusivity is essential for the SANDF to optimise its scarce resources and strengthen governance. Recommendations include embedding ethical leadership, contextualising governance frameworks to African realities, and cultivating participatory organisational cultures that align with democratic values and national development goals.
