This research is a comparative case study using a qualitative research methodology. Through critical evaluation of secondary data from multiple organizational and independent sources, the thesis assesses the contribution and interventions strategies of Australian Aid (AusAID) peacebuilding in Sierra Leone and the Solomon Islands. The study contributes to the literature in a number of ways; First, it creates opportunities for donors to re-evaluate their approach and reconsider some of the 'conditionalities' normally attached to aid for country's post-conflict reconstruction. Second, it posits that dialogue among stakeholders assists coordination, facilitates successful service delivery and cultural understanding among peacebuilding actors. Analysis of the two case studies reveals donor intervention and funding is largely political and humanitarian context driven. Donor exit strategy has major implications for post-war peacebuilding process. The study recommends, adopting a comprehensive approach is critical for successful peacebuilding; and gradual phasing out of aid is critical to sustainability.
