1. Understand the work
Marine placements run on survey and restoration. Expect transects, species counts, debris logs, coral frame maintenance and data entry, plus early starts and long days in sun and salt.

How to become a marine conservation volunteer
Marine conservation volunteering is survey work, restoration work and record keeping in support of a programme that runs whether or not you arrive.
Marine conservation volunteering is survey work, restoration work and record keeping in support of a programme that runs whether or not you arrive. This page explains what that involves, what it asks of you, and how to tell a genuine placement from a marketed one.
2. Check the requirements
Most reef placements need confident swimming. Some research streams need a dive certification or a minimum stay. Each program page lists its prerequisites.
3. Pick a season
Turtle work follows nesting and hatching seasons. Reef survey work runs year round, with visibility and weather varying by month and site.
4. Test the ethics
Ask who uses the data, who leads the work, what happens to animals in care, and what the fee covers. If an operator cannot answer, that is your answer.
5. Budget honestly
Program fee, flights, insurance, visas and personal spending. Fees on this site are itemised and drawn live from the booking system.
