This study evaluates the approach to developing the border area between Indonesia and Papua New Guinea, with a focus on creating a model for sustainable development. Using a qualitative approach, data were collected through observation and interviews in the Skouw Border Area. Analysis reveals that government strategies for border development are predominantly infrastructure-focused, leaning more towards security aspects than community and environmental empowerment. Moreover, an investment-based approach is observed. However, current policies lack a clear, principal legal basis to integrate security, welfare, and environmental sustainability approaches. Therefore, the study suggests the need for a more balanced approach that also prioritizes regional economic development and environmental sustainability. Such an approach should involve collaborative principles between central and local governments.
