This UNESCO-recognised area protects globally significant soft-sediment ecosystems teeming with sponges, ascidians, and bryozoans, while inshore waters serve as a critical calving ground for endangered southern right whales (June–October). Snorkelers explore crystal-clear shallows above seafloor gardens of colourful invertebrates and small reef fish. Access is via the long Nullarbor crossing to Head of Bight, where viewing platforms overlook the marine park.
