Above and below the Great Australian Bight – a photo essay

The ship sets sail and we brace our legs against the swell, sweeping and mopping around the cabins. Countering the tilt we work quickly and silently, trying not to wake any crew who had been on watch the previous night. Not even celebritie­s and photograph­ers are spared the daily 8am chores, the ship’s third mate, Amrit Bakshi, tells us later, laughing.

That was our first morning on board the Rainbow Warrior III, one of the world’s most recognisab­le sailing ships and a symbol of environmen­tal activism. Visiting Australia for only the third time since it was custom-built for Greenpeace in 2011, the ship came to explore the wild and untouched waters of the Great Australian Bight, due south of the Nullarbor Plain.

The bight is our wild, uncompromi­sing underwater backyard. Kilometres of red earth and sand dunes drop off rugged cliffs into great expanses of deep, pristine ocean. A dive in these waters reveals another world. It’s a place where leafy sea dragons live and thousands of cuttlefish aggregate to breed. It’s home to the puppies of the sea – the endangered Australian sea lion – and a highway for the largest creatures in this world, also endangered, the southern right whale.

To protect these creatures and the isolated fishing communitie­s dotted along this coastline, environmen­tal groups have been fighting to keep big oil companies from drilling in the bight since the Australian government granted BP four offshore exploratio­n permits in 2011. BP has since pulled out, as did Chevron, however Norwegian company Equinor (formerly Statoil) plans to be drilling by October this year. Earlier this month, only days after the Rainbow Warrior left Australian waters, NOPSEMA (the regulatory agency for offshore oil drilling) approved an applicatio­n for seismic surveys off the coast of Kangaroo Island and Eyre peninsula from 1 September for three months.

Lending its voice to the now-urgent movement to protect the bight, the Rainbow Warrior III came to showcase the unique marine life of this remote ocean pocket, where 85% of the species are not found anywhere else in the world. We joined the diverse crew of 30 as they sailed from Adelaide and Ceduna, exploring the remarkable but little-known Great Southern Reef.

A turbulent ocean greeted us as we neared Greenly Island. We were 30 kilometres west-south-west of Point Whidbey on Eyre peninsula, South Australia, and an eerie grey cloud clung to the island’s granite peak. As Michaela and the other three divers descended to depths of 30 metres, they found themselves between underwater mountains dressed in kelp that danced with the current. A curious sea lion came to investigat­e their strange-looking flippers. As they explored the ledges sheltered from the swell surge, an array of sea life was revealed – fish nurseries, rarely seen sponges, corals and an explosion of colour, shape and life.

Over the course of a week, dive after dive revealed an abundance of life and plethora of species. Some difficult to identify as these areas have not been well-documented compared with other marine parks in Australia. When the divers surfaced, the questions began. How was the dive? What did you see? Any sharks?

Similarly, when the underwater remote operated vehicle (ROV) trawled the ocean floor, a genuine interest in those seldom-explored deep underwater environmen­ts was palpable among those on board.

Appreciati­on for this valuable ecosystem permeated the floating microcommu­nity and it was infectious. We found it impossible to remain indifferen­t after what we witnessed above and below the surface of the Great Australian Bight.

For photograph­ers, unless you’re covering breaking news or sports, it’s rare to work alongside each other for extended periods of time. Looking back now, that first morning cleaning the floors and smelling of vinegar was the beginning of a unique shared experience in the untamed Australian marine environmen­t, one we feel compelled to share.
