  In Australia, the state of South Australia experienced a pronounced wave of Prussian immigration in the 1840s (particularly from Silesia region). With the prolonged isolation from other German speakers and contact with Australian English, a unique dialect known as Barossa German developed, spoken predominantly in the Barossa Valley near Adelaide. Usage of German sharply declined with the advent of World War I, due to the prevailing anti-German sentiment in the population and related government action. It continued to be used as a first language into the 20th century, but its use is now limited to a few older speakers.
  
  As of the 2013 census, 36,642 people in New Zealand spoke German, mostly descendants of a small wave of 19th century German immigrants, making it the third most spoken European language after English and French and overall the ninth most spoken language.
  
  A German creole named Unserdeutsch was historically spoken in the former German colony of German New Guinea, modern day Papua New Guinea. It is at a high risk of extinction, with only about 100 speakers remaining, and a topic of interest among linguists seeking to revive interest in the language.
