ANZTSR 1.16 Leadership in the Not-for-Profit Sector – Past Theories and Future Frameworks Changing times has meant new challenges and growing requirements for those working in third sector. Responsibilities have shifted and partnerships arrangements have changed in light of funding agreements and a growing concern for transparency. Increasingly, regulation and compliance requirements of charities have risen as the Federal and State governments de-centralise and contract services out that were traditionally delivered directly. The findings published in the Australian Government’s Productivity Commission Research Report: Contribution of the Not-for-Profit Sector, January 2010, highlight the changing and complex role of the Third Sector in Australia. This paper presents some of the findings of research that are part of my doctoral studies soon to be submitted. Forty-one CEO’s of Australian charities that undertake social and community services in Australia have been interviewed about their perceptions of change occurring in the Third Sector. The focus of my PhD study is to reflect on CEOs perspectives on contemporary expectations, in light of the pressures from stakeholders who demand strict compliance and regulation requirements. The aim of this paper is to discuss leadership theories that have been highlighted across the literature and the findings of my PhD thesis. Leaders in the nonprofit sector must hold mission and values as key drivers. They lead with a vision for a better world, mandated to change or improve a certain social condition. In spite of challenges, they believe they can make a difference, transform lives and generate public wealth (Blake et al. 2006). The literature in the non-profit sector has much to say on servant leadership and faith-based leadership. Charismatic leadership is often explored, and mainly associated with the founding leader whom can not only inspire trust and resolve conflict but has much drive and determination (Northouse 2012, Tschirhart and Bielefeld, 2012). As well as inspiring people to work, nonprofit managers have systemic inter-dependencies, multiple stakeholders and much tension in reducing mission drift and keeping a sustainable organisation in light of complex challenges. An almost commercialisation like approach to the sector is leading to much change. There is an expected sophistication at all levels of the organisation. It has become the obligation of the leaders of these organisations to be innovative and creative in broadening social capital and mobilising volunteers and donors despite the complexities. Whether the public and government fully understand the dynamics of the non-profit sector is up for debate and how far has the third sector has caught up with the management and leadership practices of the corporate sector will also be discussed. In addition to highlighting leadership theories in the third sector from the past, this paper will look at practical ways to lead that have emerged from the analysis of the data from the PhD thesis and look at the different and emerging approaches to leadership in the latest literature. It is evident that a limited conception of leadership would be an injustice to such a vibrant and multidimensional sector and new ways of thinking are required if leaders and their organisations are to resolve complex problems.
