Australian Citizenship

The process of applying for Australian citizenship varies depending on your eligibility. There are a number of different application options with different eligibility requirements. To apply for Australian citizenship you must first determine if you are eligible. You can use our Citizenship Wizard to guide you on what to do and how to apply for Australian citizenship.

Australian Citizenship by Descent

Applications for citizenship by descent are processed at the Department of Home Affairs in Australian Embassy Bangkok, Thailand. A person born outside Australia who is the child of an Australian citizen parent may acquire Australian citizenship by descent. A person becomes a citizen on the date he/she is registered as a citizen by the Department of Home Affairs. A child born overseas can be registered as an Australian citizen by descent if at least one of the parents is an Australian citizen at the time of the child’s birth.

A parent can apply for registration of Australian citizenship by descent on behalf of the child before the child reaches 16 years of age.

On 30 July 2015, Thai legislation banning commercial surrogacy came into effect. Australians are advised not to visit Thailand for the purpose of engaging in commercial surrogacy arrangements. Please see the Smart Traveller website for more information for Australians travelling to Thailand.

How to apply for Citizenship by Descent

If the applicant is under 16, a responsible parent must apply on the child’s behalf. A responsible parent is a person that has ongoing parental responsibility for the child.

Note: Under Thai law, a father listed on the birth certificate may not necessarily be a legal parent if he was not married to the mother at the time of the child’s birth.  In this situation and to avoid doubt, the mother should sign the application form.
