Port Germein is a small sea-side town in the Australian state of South Australia located about 219 kilometres (136 mi) north of the state capital of Adelaide and about 19 kilometres (12 mi) north of the city of Port Pirie on the eastern side of South Australia's Spencer Gulf overlooking Germein Bay.

Due to the shallow water along the coast, the long jetty was built to allow sailing ships to be loaded with grain from surrounding districts.

Bagged wheat came from the local area, the eastern side of the Southern Flinders Ranges via Port Germein Gorge (opened in 1879), and from the west coast in smaller boats.

[9] The historic Port Germein Jetty Site is listed on the South Australian Heritage Register.

[12] This length, which was necessary because of the town's extremely shallow beach, briefly made it the longest wooden jetty in the southern hemisphere.
