Cintai Kepulauan Mersing is a marine conservation programme that began in 2020. The programme's overall goal is to improve ocean health by increasing reef resilience and reducing threats to marine biodiversity from plastic pollution.

This project covers Sibu, Tinggi, Pemanggil, Aur and Besar Islands that are located in Mersing, Johor.

The project emphasizes increasing local community and stakeholders' participation in the conservation and management of coral reefs, and the management of plastic waste in the Mersing group of islands.
