Tumby Island is a low bedrock island in the Sir Joseph Banks Group Marine Park, lying 500 m off the southern tip of Tumby Bay on the Eyre Peninsula. Sheltered limestone reefs, seagrass meadows, and sponge gardens ring the island, creating a haven for Leafy Seadragons, seahorses, and colourful nudibranchs. The clear, protected waters and diverse underwater terrain reward snorkelers who make the short boat or kayak crossing from Tumby Bay.
