Barossa German (German: Barossadeutsch or Barossa-Deutsch) refers to a dialect of German, which was once common in South Australia. The prominent South Australian writer, Colin Thiele (1920–2006), whose grandparents were German immigrants, referred to "Barossa-Deutsch" as: "that quaintly inbred and hybrid language evolved from a century of linguistic isolation". It takes its name from the Barossa Valley, where many German people settled during the 19th century. Some words from Barossa German have entered South Australian English.
The first wave of German settlement in Australia began in 1838. German was first spoken in the Barossa Valley in the 1840s, when German Lutheran settlers from Prussia arrived in the area.
Use of the German language in Australia declined as a result of World War I. Many Germans were interned, and immigration by German people was officially banned between 1914 and 1925. In addition, the German language was actively suppressed by the Australian government during the war. For example, many placenames with German origins were changed. Lutheran schools were closed and were re-opened as state schools teaching in English.[1]
There is some evidence that Barossa German was the first language of some people in South Australia until the late 20th century. For example, Colin Thiele claimed to have spoken nothing but German until he went to school.
Because most German immigrants to the Barossa were from Prussia and Silesia, Barossa German is classifiable as a Central German dialect. It is therefore relatively close to Standard German, when compared to analogous dialects spoken by German diaspora communities around the world.
