During both world wars, in the interest of national security ‘aliens’ (residents who were not native-born or naturalised) had restrictions placed on them. All aliens entering or residing in Australia had to be registered and report all changes of name, address, job or marital status. Alien registration forms may include information on the ship and date of arrival, date and place of birth, occupation, marital status, a physical description or photograph, and addresses in Australia.
In addition, the government interned thousands of men, women and children during World War I and World War II. Most of those interned were classed as 'enemy aliens', that is, nationals of countries at war with Australia.
