How to get dual citizenship (and why you might already have it) SHARE Pick a passport, any passport: Getting citizenship through your parents or grandparents is possible for many Australians. Share Almost half of all Australians were either born overseas or have at least one parent who was. That makes us a country of immigrants, one of the most cosmopolitan populations on the planet, and by virtue of foreign descent many of us have a claim on citizenship of another country. The main reason you might want to do that is the right to live and work somewhere other than Australia. Citizenship also gives you the right to apply for a foreign passport, and that can be a real benefit for travellers. Particularly if it's an EU passport, it guarantees the right to travel, stay and work freely in any EU country.
