I was born in Australia in 1969 to Dutch dad and UK born mum. We all went back to UK in 1971 and I grew up there, going to school, getting NI number, working, able to claim benefits, married UK born man, had 3 UK born kids. We left the UK several times to have extended visits to Australia (all less than 1 year) but I never had a problem re entering the UK on my Australian passport, i just explained the UK was my home.
However in 2004 we moved to Australia, and now we want to go back. I now also have a Aussie born son who is entitled to a UK passport through his dad. We plan to go back in Dec. I am worried I will not be able to re enter the UK as I have been left so long. I read on the British High Commisions site that I might be able to apply for Right to Abode (or the sticker of entitlement) which would cost $460. I tried writing to the BHC and explaining my situation but all I received was an adult British passport application (which I dont think i am entitled to??). I have tried ringing the High Commission (on their expensive phone line) but have received conflicting info. The website says online applications only, but the online form doesnt allow for 4 children and it asks for things like a sponsor. The BHC on the phone says online application only, and to ignore those questions but I cant proceed without filling them in. The BHC also says I cannot apply until 3 months before I go, but then also said it takes approx 12 weeks to assess.

All I want to know is what i should be doing, as I am worried I will apply wrongly and be refused.
My husband needs a new UK passport and the children all need UK passports, and i dont want to pay out for them until I know I can get back OK. All the rest of our families are in the UK.
Hope someone can help or has been in a similar situation to advise.
