– 31 December 1881) Wallaroo Times (4 January 1882 – 28 July 1888) Kadina and Wallaroo Times (1 August 1888 – March 1966) Kadina, Wallaroo and Moonta Times (7 April 1966 – 29 August 1968) Yorke Peninsula Country Times (4 September 1968 – present) Another publication was the Wallaroo Wheatsheaf (December 1911 – November 1918), which was produced monthly by Roland Campbell for Wallaroo Amalgamated Co-operative Society Ltd. Its successor, Wheatsheaf (December 1918 – 16 June 1921), used the subtitle "an official organ of the Co-operative Movement of South Australia, application being made for registration as a newspaper". Economy Historically, Wallaroo was part of the "copper triangle" copper mining industry. One of the large mining chimneys still stands, aptly named the 'big stack'. Copper mining ceased in the area in the 1920s, but the old copper smelter is now a tourist attraction. From the 1880s onwards the most important economic driver in the area has been cereal cropping, despite the proximity to Goyder's Line, which traditionally marks the geographic edges of agricultural viability in South Australia. Wallaroo is a significant sea port in South Australia and is the point of international export for many agricultural products originating on Yorke Peninsula and nearby parts of the South Australian Mid North. This especially includes seeds and grain products via the Wallaroo Grain Terminal. Wallaroo's surrounds are used for growing barley, wheat and other crops such as legumes, canola, chickpeas and field peas. Tourism associated with the copper mining history and marine leisure activity has become a major part of Wallaroo's economy in the latter 1900s. The three-day Kernewek Lowender Cornish festival is held every odd year in May, with Kadina, Moonta and Wallaroo each hosting the festival for one day. From the 1990s, beachfront development in the town has accelerated with new housing developments situated at Office and North beaches. The Copper Cove Marina commenced construction at North Beach in 1997 and expects, on completion, to contain a total of 154 marina berths with a proportionate number of new residential and commercial plots. The marina development is almost one third of the size of the original township (prior to 1997). Transport Wallaroo is at the western end of the Copper Coast Highway and on the Spencer Highway. The Balaklava-Moonta and Kadina-Brinkworth railway lines closed in the 1990s. From the 1990s until 2009, the Lions Club of Yorke Peninsula Rail operated tourist services
