It says it on the link above. But the OP was born before 1983 so it doesnt matter and can get a birth certificate here gro.gov.uk/certificates/

When i arrived through border control i was told that i must leave after 6 months and they stamped my pp with a 6 month visa even though i showed them my expired brit pp i am not even allowed to work maybe now that i am also a national of another country maybe some of my rights have changed,even if i do renew my brit pp here i will still have to leave within the 6 months so why would border control stress this point if im untouchable.
I even telephoned border control to inform them that i could not find a counter signature to fill in the requirements on the application form as i have been away for so long that i dont have a counter signature who has known me for 2yrs but there reply is i should fly back to aust and do it there !!
Its all barmy to me.

Maybe the person at border control didnt know what they were talking about. They're doing a different job to the one you're phoning them about.

It's not like they will come and actively find you when your 6 months is up! And even if for some bizzare reason they did, you're British! And if an employer hires you they have broken no laws though the employer may want to see proof your entittled to work, some accept expired British Passports others dont.

Nothing has changed, British Citizens are allowed to be dual nationals and give up no rights in the UK by becoming a citizen of another country.

Did you look at the link for the Birth Certificate? You can get a new full certificate for under £20 posted to where ever you are staying.

Yes I was aware that the OP was born before 1983, but my interest was peaked because someone I know was born in the UK after 1983 but her parents are not domiciled, residents or citizens of the UK. Presumeably that means she is not a British Citizen and so cannot get a UK passport. I had better let her know as she is under the impression that she is British because she has a UK birth certificate.

I was actually in the same position as the OP, but in reverse in that I travelled to NZ on a UK passport because my NZ had expired. The nice immigration lady said if I stayed after the period of the visitor permit I should contact immigration so that I am not recorded as an overstayer. She didn't make a big issue over it, I imagine she is just ensuring they don't chase me up when they don't need to. It sounds to me like border control in the UK either don't believe the OP's story or were too busy to give anything other than the official line - at the end of the day it is not their decision whether you are British or not, but nevermind, you are British so it's not a big deal.

Correct - if both of her parents were temporary, then she is not British (one parent who is a British citizen/PR is required). There are special rules for some situations, such as EU/EEA parents.

If by some chance she lived in the UK until age 10, she is normally entitled to register as a British citizen.

Stop wasting your time "calling border control". Your pre-1983 birth certificate is proof of British citizenship but you now need a travel document. You have two options:

1. Contact the Passport Office, http://www.passports.gov.uk
They do normally need a countersignature to issue a British passport. If you cannot provide one, ask if there are any special provisions for those who cannot do this. Would someone who has known you for 6 months suffice?

2. Right of Abode stamp in your Australian passport. Contact the Home Office: http://www.ukba.homeoffice.gov.uk/br...mrightofabode/

If you try to get readmitted on your Australian passport without 1 or 2 then you may have problems. But if you bring your birth certificate you may (or may not) be ok.

Ok got back from cyprus yesterday and can now confirm some of the questions/answers:
Yes true no border control check your passport on exit so even using my aussie p/p to enter the UK giving me max 6month with work restrictions ie not allowed to work i could still work because i have a N/I number and am brit citz so i could make a mock of border control and second having a greek cypriot surname gives me the right to enter cyprus and work for as long as i want using my aussie p/p so why bother to get a brit p/p just a waste of time and not to mention the rip off charge.

Maybe because if you'd had a Brit passport in the first place you would have saved yourself a lot of anguish and people on here a lot of trouble trying to help you out?

Well polly it wasnt my intention to mess people around i tried to get a brit passport but this was looking difficult so i renewed my aussie one which was due to expire and now realising that i can live without the other pp im glad i didnt renew my brit pp though thanx to all who gave there time to help me i did appreciate it cheers .
