This paper aims to understand the financing decision for a seaport project in Indonesia from various perspectives. An online survey and a focus group discussion are conducted to gain insights from the Indonesian seaport stakeholders regarding the most effective financing vehicle for seaport infrastructure projects. Furthermore, this paper presents a case study of a seaport infrastructure project financing strategy by constructing cash flow simulation model based on different financing scenarios to illustrate the effectiveness of the alternate ways to finance seaport projects. The survey finds that Indonesian domestic banks syndication, and Public-Private Partnership schemes with government fiscal support are the two most awaited financing vehicles. The cash flow simulation shows that, when a project's internal rate of return is the basis of the decision to distribute project dividend, the project sponsors could benefit from adjusting the project's capital structure. This paper contributes to the research and management practice by revealing the expectation and reality of infrastructure project financing in Indonesia.
