Australia’s southern coast looks almost empty—but beneath its cliffs, limestone plains and the Great Australian Bight lies a landscape far more extraordinary than it appears.

In this DiscoverTube documentary, we explore why so few people live along this enormous coastline, the geology that shaped it, and the discoveries scientists are making offshore. CSIRO research has identified 277 species new to science in the Great Australian Bight and mapped previously unknown deep-sea canyons and volcanic seamounts.
