Australian law in 1939 designated people "enemy aliens" if they were Germans or were Australians who had been born in Germany; later, it covered Italians and Japanese as well. The Australian government would therefore intern them, sometimes for years until the war ended, in camps such as the isolated
Tatura Internment Camp 3 D which held approximately 300 internees thus deemed "enemy aliens", mostly families, including children as young as two years of age, such as
Eva Duldig — who two decades later represented the country that had interned her in tennis at Wimbledon.

There, armed soldiers manned watchtowers and scanned the camp that was bordered by a barbed wire fence with searchlights, and other armed soldiers patrolled the camp.
Petitions by many of those interned to Australian politicians, stressing that they were Jewish refugees (such as
Karl Duldig,
Slawa Duldig, and their toddler) and therefore being unjustly imprisoned, had no effect.

United Kingdom
At the outbreak of World War II in 1939, the United Kingdom had become a place of refuge for people who had fled Nazi persecution, including Jews and political refugees. At first, with the outbreak of war, the British government – in accordance with its policy of
Defence Regulation 18B – placed these refugees with other enemy aliens regardless of their political allegiances. Later on, when Italy also declared war on Britain, significant numbers of
British Italians were also interned as enemy aliens.

Serving as German nationals in the British forces was particularly dangerous, since, in case of taken captive, with a high probability they would have been executed as traitors by the Germans. The number of German-born Jews joining the British forces was exceptionally high; by the end of the war, one in seven Jewish refugees from Germany had joined the British Army. Their profound knowledge of the German language and customs proved useful. Many of them served in the administration of the British occupation army in Germany and Austria after the war.

by President Roosevelt during wartime, alongside many German- and Italian-Americans. However, many Japanese-Americans and Italian-Americans were not actually "aliens", as they held American citizenship. The term "enemy alien" referred only to non-American citizens who were nationals of Axis countries. Included in this number were thousands of resident aliens who were prohibited from applying for citizenship by race-based naturalization laws; when war was declared against their native countries, their status changed from "resident" to "enemy" alien. Therefore, German American, Italian American, and Japanese American permanent residents were classified as enemy aliens and interned as such.
In total 10,905 Italian Americans and approximately 110,000 Japanese Americans were interned in many different camps and sites across the country. German Americans were held in more than 50 different locations.
Citizens of an enemy country who lived in the United States during World War II were required to have an "Enemy Alien" card, and to register monthly with the authorities.
