South Australia is a state of extreme wilderness. It's home to the 100km-long Bunda Cliffs facing the Great Australian Bight, the empty expanse of the arid Nullarbor Plain and the red dunes of the Simpson Desert. To the north is Coober Pedy an opal mining town and the Flinders Ranges, further north is Lake Eyre the lowest point in Australia. To the south is the Fleurieu Peninsula and further south the Limestone coast. Its capital, Adelaide, nicknamed “City of Churches” and known for its rich culture, close by is the Barossa Valley and the Mclaren Vale vineyards.
