Opened in July 2015, the Sisters’ Islands Marine Park Public Gallery on St John’s Island complements the outreach programmes at the Sisters’ Islands Marine Park. The Public Gallery features the rich marine biodiversity in Singapore's waters and provides an overview of the Sisters' Islands Marine Park. A seminar room and teaching lab for school and community groups are also provided as extensions to the Public Gallery.

New exhibits have been added to the bigger and enhanced Sisters’ Islands Marine Park Public Gallery. Visitors can explore a mangrove mesocosm, a viewing pool, aquariums and other new displays.
