Embark on a once in a lifetime opportunity and explore the diverse reefs of the Great Barrier Reef!

Join a Great Reef Census expedition with Citizens of the Great Barrier Reef and discover the hidden gems of rarely visited reefs that few have seen before.

These expeditions offer a unique opportunity to learn about different monitoring techniques and upskill in marine biology field techniques. Imagine being a marine biologist for a week!

The Great Reef Census is an innovative approach to surveying that empowers every day individuals to contribute to valuable scientific research.

You’ll witness firsthand the importance of Census as you collect crucial reconnaissance imagery. All this whilst immersing yourself in the Reef environment and experiencing the vibrant marine life that it has to offer!
