Limestone Coast

South Australia

The Limestone Coast is a treasure trove of natural wonders which features 20 sites of international or national significance.

The Limestone Coast is a name used since the early twenty-first century for a geographical region and for a tourist region both located in the south east of South Australia which immediately adjoins the continental coastline and the Victorian border.

From the Victoria border to the Younghusband Peninsula this area has been settled since the 1840s and supports farming, viticulture, forestry and tourism. Towns of the coast include Bordertown, Keith, Millicent, Mount Gambier, Penola, and Naracoorte, the coastal resorts of Beachport, Kingston SE and Robe, and the wine-growing regions of Coonawarra, Padthaway, Wrattonbully and Mount Benson.

The Coonawarra wine region is a wine region centred on the town of Coonawarra in the Limestone Coast zone of South Australia. It is known for the Cabernet Sauvignon wines produced on its "terra rossa" soil. Coonawarra is an Aboriginal word meaning "Honeysuckle". It is about 380 km southeast of Adelaide, close to the border with Victoria.

There are deep limestone deposits created from the coral and other sealife. The limestone in Victoria Fossil Cave and the other Naracoorte Caves contains are Australia's biggest source of fossils and a World Heritage site.

Mount Gambier (also known as Ereng Balam,meaning eagle hawk) is a maar complex associated with the Newer Volcanics Province. It contains 4 lake-filled maars called Blue Lake, Valley Lake, Leg of Mutton Lake, and Brownes Lake. It is one of Australia's youngest volcanoes, but estimates of the age have ranged from over 28,000 to less than 4,300. The most recent estimate, based on radiocarbon dating of plant fibers in the main crater (Blue Lake) suggests an eruption a little before 6000 years ago.
