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.

Today we're traveling back to South Australia for an update on the devastating toxic algal bloom that's been unfolding there over the last seven months, and what it it's been like for the divers who know and love these waters.

Marine Biologist and Divemaster Sarah Franke from Divers for Climate has just returned from a research trip to learn about how the disaster is impacting the South Australian community. She'll also take us inside the Senate Inquiry into the disaster, and let us know which of SA's dive sites are still safe to visit.

Scott Reef, Australia’s largest remote offshore reef, is a breathtaking sanctuary for corals, fish, rare sea snakes, nesting turtles, and pygmy blue whales. But this natural wonder is under threat from a mega gas drilling and carbon dumping proposal. Fossil fuel campaigner Louise Morris from the Australian Marine Conservation Society joins us to explain what’s at stake and how we can fight back.

Plus: we unpack Australia’s new 2035 climate target with AMCS Reef Campaigner Lissa Schindler — and why experts say it’s not enough to protect our oceans.

Cyclones are part of life in the tropics, but climate change is making them stronger and more destructive. On the Great Barrier Reef, their force can pulverise thriving coral gardens into unstable rubble fields where baby corals struggle to grow. But there’s hope! In this week’s episode, we dive into an innovative solution that’s helping damaged reefs bounce back — and discover how you can play a role in bringing them back to life again!

This week's guest: Freda Nicholson, marine biologist and Program Manager for Mars Sustainable Solutions.

Seagrass meadows are the unsung heroes of the Great Barrier Reef – nurseries for fish, food for turtles and dugongs, and a frontline defence against climate change. But after a massive die-off, Dr Tim Smith and the team at JCU TropWATER faced a huge challenge: how do you restore these fragile ecosystems while dealing with crocodiles, stingers, and waist-deep mud?

The answer: helicopters, hovercraft, dugong poo, 2,000 baby seagrass plants – and an army of everyday volunteers.

🎧 In this episode, dive into a world-first tropical seagrass restoration project and discover how you can be part of the solution.
