You are looking at part of the largest of five such graveyards in Port Adelaide.
All will be explained in a few episodes’ time.
Suffice for now that these graveyards’ occupants are not human corpses or skeletal remains, and that various living beings – plants, birds, fish, reptiles and mammals – thrive in these graveyards.

The birds are cormorants, aka “shags”. (two species thereof)
The greenery is mangrove forest.
Australia has 41 mangrove species.
Only two other nations (Indonesia and Brazil) have more extensive mangrove forests.
Victoria’s and South Australia’s mangroves are of one species, only – Avicennia marina, commonly known as grey mangrove or white mangrove,
Wilsons Promontory National Park – four degrees south of Port Adelaide – is home to the world’s southernmost mangroves; the tip of “the Prom” is the “bottom” of the Australian mainland.
