Aboriginal The
Narungga are the group of
Indigenous Australians whose traditional lands include what is now termed
Yorke Peninsula in
South Australia. The name "Wallaroo" comes from the Aboriginal word
wadlu waru, meaning wallaby urine. The early settlers tried to copy the Aboriginals by calling it Walla Waroo. However, they found this too big to stamp on the wool bales, so they shortened it to Wallaroo. During the early years of European settlement, the Narungga maintained a healthy population, but it has since declined.
European Matthew Flinders was the first European to visit the location. When he sailed by on 16 March 1802, he recorded that "the intermediate coast ... which extends several leagues to the north of the point, is low and sandy, but a few miles back it rises to a level land of moderate elevation, and is not ill-clothed with small trees." Wallaroo was first settled in 1851 by a sheep grazier, Robert Miller. In 1857,
Walter Watson Hughes purchased the land and named it "Walla Waroo". The name was subsequently shortened to "Wallaroo". In June of that year, the cadastral
Hundred of Wallaroo was proclaimed, allowing the surrounding land from coast to Wallaroo Mines to be allotted and sold as sections. The smelter grew and developed to eventually become the largest copper smelter outside of
Wales. In addition to copper, the smelter also produced gold and lead, and included a
sulphuric acid works, forming the largest and most important producer in
Spencer Gulf, until the
Port Pirie smelters were established in 1890. Distilled sulphuric acid was also produced and superphosphate was manufactured between the 1890s and 1920s. The area's population peaked at 5,000 in 1920, and Wallaroo was Yorke Peninsula's largest and most important port until when copper production ceased in 1923. An automatic grain loader was built on the town's third jetty in 1958 and is currently in use. The local railway yards expanded to a significant size, but the use of the line diminished and it was closed in the 1990s. Tourist trains occasionally used the line between Wallaroo and Bute until 2009. The line was pulled up in 2014. Today Wallaroo remains as a major
grain port. ==Heritage listings==
