My father is a British Citizen and holds a British passport and Australian passport. My mother is from the Philippines. I was born before they officially got married, however I am still able to hold my Australian passport and have citizenship for this country.
Currently I have an Australian and Philippine Passport.
I was born in the Philippines, but I reside in Hong Kong and go to school here.
Both my grandparents from my Father's side are British citizens, however they moved to Australia after deciding to leave the UK.
