The largest internment camp in Australia during WWI was at Holdsworthy, near Liverpool on the outskirts of Sydney. The camp held between 4,000 and 5,000 internees, most were either from the Austro-Hungarian empire, staff of German companies temporarily living in Australia, crews of vessels caught in Australian ports and naturalised and native born Australians of German descent. Prisoners were interned without trial, often without knowing their "crime", and without the knowledge of their families. Some were brought from camps in other Australian states that were closed early in the war. Many from Western Australia, who had been employed in gold fields around Kalgoorlie, had originally come from states within the Austro-Hungarian Empire such as Serbia and Croatia. About 700 of those interned were naturalised British subjects, and 70 were Australian born. Despite this many of these internees were deported to Germany after the war.
