If you were born in a country that is different to either of your parents, or your grandparents, or you have a connection back to the UK, Ireland or a former British territory, then you might have a claim. Our citizenship team is led by world-renowned UK immigration and British nationality expert, Philip Gamble, and they're just an email or phone call away.

Australia (Cocos (Keeling) Islands, Christmas Island, New Guinea, Papua)

Australia is an independent country and is part of the Commonwealth. Up until 31 December 1948, it fell within the British Crown dominions.

Christmas Island and the Cocos (Keeling) Islands form part of Australia. However, at various times before 1957, they formed part of the colony of Singapore (and, in the case of Christmas Island, a separate Crown colony during 1958).

Papua was part of Australia up until 15 September 1975, at which point it combined with New Guinea to form Papua New Guinea. New Guinea was an Australian Mandated Territory (up until 12 December 1946) and an Australian Trust Territory (up until 15 September 1975).
