World-renowned underwater photographer Michaela Skovranova (@mishku) travelled to Port Lincoln, Baird Bay and Rapid Bay in South Australia to explore the wild landscapes and unique flora and fauna of the Great Australian Bight.

The Great Australian Bight is a pristine wilderness, home to a critical whale sanctuary, tight-knit coastal communities, hundreds of kilometres of towering cliffs and more unique species than the famous Great Barrier Reef. But the beautiful Bight is at risk. Big oil, led by Norwegian company Statoil, has eyes on the Bight. If their plans go ahead, the threats from an oil spill, deafening seismic blasting and pollution are all too real.
