What do underwater art museums, bomb tests, and citizen science have in common? They're all part of the story of the Great Barrier Reef’s past, present—and possible future.

Our guest this week is Dr. Adam Smith—freediver, marine biologist, and founder of Reef Ecologic, a Townsville-based social enterprise leading innovative reef conservation through research, education, and community action.

In this episode, we dive into how art, science, and storytelling are being used in powerful ways to protect one of the world’s most iconic ecosystems. You'll discover how public art installations beneath the sea are connecting people to the reef, how citizen science is turning everyday adventurers into ocean guardians, and what we can learn from extreme events like ship groundings and out-of-control seaweed outbreaks.
