The United Kingdom is making changes to the Electronic Travel Authorisation (ETA) requirements for travellers. If you're planning travel to the UK these changes may impact you. Particularly if you're a dual citizen.
What's happening?
From 25 February 2026, to board a flight to the UK you will need one of the following:
- if you’re not a dual citizen
- an ETA
- a valid visa
- if you have dual citizenship with the UK
- a valid British or Irish passport
- a Certificate of Entitlement (CofE) attached to your Australian passport.
Check if you need a UK ETA or visa.
How does this affect me?
Your travel won't be affected if:
- you’re not a dual citizen and you have an ETA or visa
- you’re a dual citizen with an ETA or visa and you're arriving in the UK before 25 February using your Australian passport
- you have a valid British or Irish passport
- you have a valid CofE sticker in your Australian passport, or a digital CofE.
Dual citizens travelling to the UK on or after 25 February will need to present a valid British or Irish passport or CofE attached to your Australian passport to board your flight. Dual citizens can't travel to the UK using an ETA.
How do I know if I'm a dual citizen?
You might be a citizen if your parents were born in the UK or a British territory. It depends on the date you were born and where your parents are from.
British citizenship by descent is automatic if you meet the conditions. This means you don't need to apply for citizenship to be considered a citizen.
The UK Government has more on types of British nationality and how to check if you're British.
What do I do now?
If you're a dual citizen and you want to travel to the UK, you must either:
- apply for a British passport - if you’re from Northern Ireland, you can apply for an Irish passport if you prefer
- apply for a Certificate of Entitlement, which lets you travel using your Australian passport.
You can also renounce your British citizenship if you don't want to be a dual citizen.
If you’re not a dual citizen, apply for an ETA or visa.
