Salt Creek, South Australia in the context of Coorong National Park

Coorong National Park is a protected area located in South Australia about 156 kilometres (97 mi) south-east of Adelaide, that predominantly covers a coastal lagoon ecosystem officially known as The Coorong and the Younghusband Peninsula on the Coorong's southern side. The western end of the Coorong lagoon is at the Murray Mouth near Hindmarsh Island and the Sir Richard Peninsula, and it extends about 130 kilometres (81 mi) south-eastwards. Road access is from Meningie. The beach on the coastal side of the peninsula, the longest in Australia, is also commonly called The Coorong.

The Coorong lies within the traditional lands of the Ngarrindjeri people, an Aboriginal Australian group. Notable locations within the park include Salt Creek, Policeman's Point, Jack Point, and Woods Well.
