The bay lies to the north east of Cape Leeuwin which is the most south-westerly mainland point of the Australian Continent, in the state of Western Australia.
On Matthew Flinders Terra Australis Sheet 1 1801–1803 the area was originally known as Dangerous Bight.
The Flat Rock site is complete and has been called "Augusta Boat Harbour" by the department of Transport.
Like the majority of the southwestern coastal regions of Western Australia, Flinders Bay experiences a cool-summer Mediterranean climate with cool to warm summers and mild, wet winters.
The ranch is based on an artificial reef made up of 5000 (as of April 2016[update]) separate concrete units called abitats (abalone habitats).
The ecosystem enrichment of the bay also results in growing numbers of dhufish, pink snapper, wrasse, samson fish and other species.
