Abstract: Climate change and global warming are predicted to affect the lives of people in coastal areas and small islands which need facilities and infrastructure to develop all the socio-economic activities. However, Indonesia does not currently lead to sustainable development on its small islands. This study was aimed to determine the extent to which Indonesia has done a sustainable development on its small islands based on infrastructure and socio-economic community. The research was descriptive-exploratory where the data was collected from several sources of literature, writing and research and then presented exploratively. Based on the findings, the availability and utilisation of infrastructure to support the community needs and to preserve the environment on the small islands have not been sustainable. The government should develop the socio-economic and infrastructure aspects. Socio-economic aspects include population density, access to beaches, public participation, job employment, income, access to market and price of goods. Meanwhile, infrastructure aspects include the availability of green lanes and sea transportation, drainage, management of waste and public bathing, washing and toilet facilities and clean water.
