In 1938, due to increasing anti-semitism in Austria, Freund-Zinnbauer decided to emigrate and contacted a fellow Lutheran pastor he knew in Adelaide.[2] Upon his arrival in Australia in 1940, however, he was now considered an enemy alien and was interned in Tatura. In 1942, he was transferred to the Loveday Camp in rural South Australia, and was finally released in 1944 after being reclassified as a refugee.[2]
After the war, he spent most of his time with the church assisting European immigrants settle into new lives in the Adelaide area.[2] He died in 1978 and his wife in 1980.
