Yankalilla Bay is a long, wide bay in south-eastern South Australia, on the Fleurieu Peninsula.
It is on the south-eastern coast of the Gulf St Vincent,[1] as it opens into the Southern Ocean.
The rivers can adversely affect the ecology of the sea, in particular the health of the reef and seagrass.
[1][3] Yankalilla Bay is known for being the site of the ship's graveyard of HMAS Hobart, which was scuttled on 5 November 2002 off the coast between Wirrina Cove and Normanville to create a dive wreck and artificial reef.
[4][5] The HMAS Hobart Memorial Lookout is located at Little Gorge.
