Urgent Passport Warning for Australian-British Dual Citizens Travelling to the UK
Australian citizens holding dual British or Irish citizenship are facing a critical deadline, with new UK entry rules set to be strictly enforced from February 25, 2026. This change means that travelling to the United Kingdom solely on an Australian passport will no longer be permitted, potentially causing significant disruptions and unexpected expenses for thousands of expats.

The UK’s Electronic Travel Authorisation (ETA) scheme, which has been in a grace period, will be fully operational from this date. While the ETA system is designed for travellers from 85 visa-exempt countries, including Australia, there’s a crucial distinction for dual citizens. These individuals, by virtue of their British or Irish citizenship, are exempt from needing an ETA. However, this exemption comes with a strict condition: they must use their valid British or Irish passport for travel to the UK.
The Unexpected Cost and Hassle
For many, this change has come as a surprise. Danny Flint, an Australian-British dual citizen living in Brisbane, is among those who have been caught off guard. He has been travelling to the UK for years using his Australian passport without issue. Now, with his British passport expired, he faces the prospect of renewing both his and his family’s passports, an expense he estimates will run to around $600.
“It doesn’t feel fair, and I’m not sure why it has been introduced – definitely another expense, and hassle,” Mr. Flint told reporters. “Why could an Australian citizen travel on the Australian passport, but a dual citizen couldn’t?”
The cost of renewing or replacing a passport in Australia can be substantial, with each application costing approximately $189, plus postage fees. Furthermore, the processing time can be lengthy, with applications potentially taking up to 10 weeks to be processed and delivered. The inconvenience and expense have even led some, like Mr. Flint, to consider renouncing their UK citizenship.
Born in Britain, Travelling on an Aussie Passport
Wendy Hilsum, another Queensland resident, shares similar concerns. Born in the UK, she has relied on her Australian passport for years. “I prefer to just have the one passport,” she stated. “Australia’s passport is the most expensive in the world and it states on there that I am an English-born citizen. Not sure why they need that extra money from us.”
Ms. Hilsum, like Mr. Flint, has elderly parents in the UK and prioritises the ability to travel easily to visit them. She expressed her frustration at the prospect of being denied boarding due to an outdated passport.
Official Warnings Issued
The Australian government, through its Smart Traveller service, has officially alerted expats to the impending changes. The notice clearly states:
- “Dual citizens may not be able to board a flight to the UK without a valid document.”
- “Dual Australian-British and Australian-Irish citizens need a valid British or Irish passport or certificate of entitlement in another valid passport to enter the UK.”
- “The UK government has advised these requirements will be strictly enforced from 25 February.”
The UK Home Office has reiterated these warnings, advising dual British citizens to ensure they possess a valid British passport or a certificate of entitlement to avoid being denied boarding. From February 25, 2026, dual British citizens who cannot present the required documentation will face additional identity checks and will be unable to pass through UK passport control until their British nationality is verified.

What is a Certificate of Entitlement?
A certificate of entitlement serves as proof of a person’s right of abode in the UK. Individuals who hold such a certificate will need to apply for a new one if their passport expires. This certificate, along with a valid British or Irish passport, is crucial for dual citizens entering the UK from the specified date.
Do Other Australians Need an ETA?
For Australian citizens who do not hold dual British or Irish citizenship, the ETA scheme applies as usual.
- Requirement: An approved ETA is necessary before entering the UK.
- Application: It is recommended to apply at least three business days before travel.
- Process: The application involves a fee, providing contact and passport details, and a valid photo. Suitability and criminality questions will also be asked. Most applications receive an automatic decision within minutes via the UK ETA app.
- Validity: An ETA allows for a stay of up to six months and expires after two years or when the holder’s passport expires. It does not permit paid or unpaid work.
- Exemptions: British and Irish citizens are exempt from needing an ETA.

From February 25, 2026, travellers without a valid ETA will be unable to board their transport and will not be able to legally travel to the UK.
UK Minister for Migration and Citizenship Mike Tapp commented on the ETA system, stating, “ETAs give us greater power to stop those who pose a threat from setting foot in the country and gives us a fuller picture of immigration.” He also highlighted the benefits for travellers, noting that “Digitising the immigration system ensures the millions of people we welcome to the UK every year enjoy a more seamless travel experience.”
