My dad has an ozzie passport, and I have managed to get Australian citizenship by default as im under 25. I currently live in the UK and only have a British passport. Does anyone know If I still need a visa or ozzie passport if I want to emmigrate to oz? Or can I just turn up at customs with my Brit passport and my certificate of citizenship? Bit of a technical question i know, just thought someone on these forums might have an idea.
