Citizenship Ceremony

Citizenship Ceremonies are a formal occasion during which candidates take the pledge of allegiance to Australia.  Each ceremony takes approximately 1 - 2 hours depending on the number of candidates.  Members of Parliament, Councillors and special guests are invited to attend each ceremony.

Each candidate will be required to bring with them on the night of their ceremony, photographic identification to assist with the registration process.

The City of Onkaparinga hosts regular Citizenship Ceremonies throughout each year, with a ceremony held annually on 26 January, Australia Day and where possible, 17 September, Australian Citizenship Day.
