I think it may be the Great Australian Bight. Maybe if you looked on a map of Australia you might find the same answer or even a better one!!
Yes th Great Australian Bight is a part of the south coast of Australia.
No. The Great Australian Bight lies off the southern coast of Australia, meeting the coastlines of South Australia and Western Australia.
The Great Australian Bight is bordered by the two states called South Australia and Western Australia.
The Great Australian Bight
This is nothing but an off-hand guess: Australia. I'm thinking of the Great Australian Bight that makes up most of Australia's southern coast. It is, I believe, the largest bight on the planet.
Depending on the context (usage), a bight [as a noun] may be a bay or gulf, a river bend, the body of water surrounded by such a bend (like an oxbow...), the middle part of a rope that is different from the ends of the rope, or the loop or bent part of a rope that is different from the ends. As a verb, it means "to fasten, or bind with a bight of rope". In Australia, the Bight (the Great Australian Bight, that is...) is that major indentation along the South coast, spanning Cape Pasley in Western Australia to the Eyre Peninsula in South Australia.
A bight is a bend in the coast that forms an open bay. The Great Australian Bight is such a bend, forming a massive open bay on the southern coast of Australia. Hence, "Great" - large; "Australian" - it is in Australia; "Bight" - bend in the coast that forms an open bay.
Bight further
The Nullarbor Plain is in Australia. It is a large, flat, treeless desert in the south of the continent, which parallels the Great Australia Bight.
The Nullarbor Plain lies south of the Australian desert areas and north of the Great Australia Bight, where the Southern Ocean meets Australia's coast.
Long ago, the world had only two super continents, Laurasia and Gondwanna. Gondwanna was composed of the southern continents, and these gradually split apart, and in particular, Antarctica separated from Australia. You'll find a good fit between the Australian Bight and part of northern Antarctica. That is the current explanation.
