What changes for Australian-British dual citizens from 25 February?

They must enter the UK as British citizens, not as visitors. That means boarding with a British passport or proof of right of abode in an Australian passport. Airlines will deny boarding if documents do not meet UK ETA requirements and carrier checks. Start with your British passport.

Is an ETA needed if I am a British citizen with an Australian passport?

No, British citizens do not receive an ETA. If you have the right of abode but no British passport, you should hold a Certificate of Entitlement UK in your Australian passport. Without that or a British passport, airlines are likely to refuse boarding for UK-bound flights.

Could airlines waive the rules if I bring other documents?

Unlikely. Carriers face fines and return costs for carrying ineligible passengers. australian british dual citizens who cannot show a British passport or right‑of‑abode evidence will usually be denied boarding. Other IDs or old passports rarely help. Rebooking fees and fare differences may then apply under fare rules.

How should I prepare bookings for a family with mixed passports?

Enter API details early, ensure each traveller’s ticket matches the document used to travel, and carry printed proof for minors. If one parent is a British citizen, check whether the child qualifies and has the right document. Allow extra airport time in late February and March for manual checks.
