You may have lost or given up your Australian citizenship:
- by acquiring the citizenship of another country before 4 April 2002 (before this date you automatically lost Australian citizenship by becoming the citizen of another country)
- by giving up or renouncing your Australian citizenship to retain or acquire another citizenship or avoid significant hardship
- as a child because your responsible parent or parents ceased to be Australian citizens.
If you became a citizen by application you can have your citizenship taken away if you are found to have committed a serious criminal offence prior to gaining citizenship. Australian citizenship can be revoked if:
- you have been convicted of making a false statement or representation in relation to your application to become an Australian citizen
- you are convicted of a serious criminal offence at any time prior to becoming a citizen involving a sentence of 12 months or more
- your approval to become an Australian citizen was gained as a result of migration-related fraud
- your approval to become an Australian citizen was gained as a result of third party fraud; for example, fraudulent conduct by a migration agent in the citizenship application
- it would be contrary to the public interest for you to remain an Australian citizen.
An Australian citizen by birth cannot have their Australian citizenship revoked. Similarly, a person conferred citizenship, after fully disclosing all relevant factors, cannot have their Australian citizenship revoked.
People who have their citizenship revoked can be removed from Australia.
Children under the age of 18 may also have their citizenship revoked unless the other responsible parent is an Australian citizen or the child would become stateless.
