Last weekend at The Art of Dining Melbourne, something caught people off guard, in a good way.

Nestled among the market’s tables and faces was a tablescape unlike anything most visitors had seen before. Beautiful, tactile, and built entirely from discarded oyster shells. It stopped people. They leaned in, touched the surface, and asked questions. And that was exactly the point.

This is the story behind it.

Meet Shuck Don’t Chuck

The tablescape was created by artist Emma-Sadie Thomson, in collaboration with Shuck Don’t Chuck, which is The Nature Conservancy’s award-winning oyster shell recycling program working to restore lost shellfish reefs across Port Phillip Bay.

Here’s why that matters. Centuries ago, more than half of Port Phillip Bay’s seafloor was alive with oyster and mussel reefs. These were thriving ecosystems that filtered water, sheltered fish, and supported entire food chains. Overharvesting, pollution, and disease gradually wiped them out. And when the reefs disappeared, so did the fish populations, the water quality, and the habitats that depended on them.

Shuck Don’t Chuck is changing that.

Shells collected from Melbourne restaurants and seafood wholesalers (the very same shells that would otherwise end up in landfill) are returned to the bay. There, they become the base for entirely new reef systems, giving juvenile oysters and mussels somewhere to attach and grow, meaning waste becomes habitat.

Why Healthy Reefs Matter to All of Us

A single oyster can filter a bathtub’s worth of water every day. That cleaner water supports seagrass meadows, which shelter juvenile fish and strengthen the wider marine ecosystem. Shellfish reefs also help capture carbon and protect coastlines from erosion.

In short: when the reefs thrive, the bay thrives. And when the bay thrives, so do we.

Where Design Comes In

Emma-Sadie’s tablescape, a terrazzo-like surface made from discarded oyster shells developed with Change Climate, gave people something to stop and look at at The Art of Dining. 

You didn’t need to read a sign to understand it; the material tells the story. These shells were heading for landfill, and instead they became a centrepiece that people gathered around all weekend, prompting some curious, genuine conversation all weekend.
