Understanding the UK Dual Citizenship Passport Changes
Starting from February 25, a significant change will affect all dual Australian-UK and Australian-Irish citizens who are planning to enter the United Kingdom. This new rule requires that individuals with dual citizenship must use their British or Irish passport when entering the UK. This adjustment is part of an updated electronic travel authorisation (ETA) scheme that came into effect on January 8, 2025.
The ETA is an entry requirement for non-UK or Irish passport holders and costs £16 ($30.50). It can be applied for online, making it a straightforward process for those who need it. However, this change has caused some confusion among Australian dual-citizens planning trips to the UK, as previous arrangements allowed them to use their Australian passports if they had an ETA.

Why the Change?
Previously, dual Australian-British and Australian-Irish passport holders could enter the UK using their Australian passport, provided they had an ETA. This loophole was something the UK government aimed to close. The new rules clarify that British or Irish passport holders are not eligible for an ETA, which means they must use their UK or Irish passport to enter the country.
This change has led to questions about whether dual citizens need to renew their expired passports. The short answer is yes. However, the UK has issued temporary guidance allowing entry with an expired UK or Irish passport, as long as a valid passport with an ETA (such as an Australian passport) is also presented. It’s important to note that this temporary guidance does not specify how long it will remain in place.
There is a risk involved, as airlines are responsible for returning passengers who are denied entry to the UK. This decision often rests with the discretion of airline staff, who may determine the acceptability of documents upon check-in.

How to Renew Your Passport
Renewing a passport is a relatively simple process. For UK citizens, the renewal can be done online at the gov.uk website. The cost is £94.50 ($190) for an adult and £61.50 ($124) for a child. Irish citizens can renew their passports through the Department of Foreign Affairs Passport Online website, with a cost of €75 ($131) for a standard 10-year Irish passport.
An alternative to renewing a passport is applying for a Certificate of Entitlement, which proves right of abode in the UK. However, this option is significantly more expensive, costing well over $1000, making it more practical to simply renew a passport.
Who Is Affected?
A large number of Australians are likely to be affected by these changes. According to the Australian Bureau of Statistics, almost a million Australian residents were born in the UK. While some of these individuals may be in Australia on a visa and not hold Australian citizenship, adding those born in the UK to those who qualify for UK citizenship through parentage results in nearly two million people potentially eligible for a UK passport.
When considering dual Irish-Australian passport holders, the total number increases further. In the year ending June 30, 2025, over a million Australian residents returned from short-term visits to the UK, suggesting that many of these visitors could be dual nationals.
Determining Your Dual Citizenship Status
If you were born in the UK, you are most likely a citizen. If you were not born there but one or both of your parents were UK citizens, you might also be a citizen. Under the new rules, dual citizens will need a UK passport to enter the country.
For those born outside the UK to a British parent, your citizenship depends on when and to whom you were born. If you were born on or after January 1, 1983, and your mother or father was a British citizen, you are likely automatically a British citizen. If you were born before January 1, 1983, and your father was a British citizen at the time and married to your mother, you may also be a British citizen without needing to apply.
The UK government provides a website where you can check your citizenship status. However, if you were born in Australia to a British parent and never applied for a UK passport or citizenship, border control may not be aware of your status. For some Australians, a UK passport might be seen as an inconvenience rather than an advantage, especially post-Brexit. In such cases, renouncing UK citizenship could be a better option.
Key Points
- From February 25, dual Australian-British and Australian-Irish citizens must use their British or Irish passport to enter the UK.
- The UK will temporarily allow entry for those with expired UK or Irish passports.
- Australians who have acquired British citizenship from their parents may also be affected.
