Mandatory British Passport for Entry

Airlines will now require specific documentation before allowing dual nationals to board.

Under the new UK passport rules change, dual citizens are now “expected to” use their British passport when traveling to the United Kingdom. In the past, many Australians used their Australian passport for the entire journey. However, the introduction of the new electronic ETA system makes this much more difficult.

The Home Office is enforcing these checks to ensure all passengers have the correct digital clearance. Since dual citizens are not eligible to apply for an ETA, their Australian passport will not be recognized by the airline’s pre-departure screening. This means showing a valid British passport is now the most practical way to travel.

The Impact of the New ETA System

Digital screening is becoming mandatory for all travelers from visa-exempt countries.

The UK’s ETA system (Electronic Travel Authorisation) is a digital permit for visitors who do not need a visa. While it costs only £10 (around $20 AUD), it is strictly for non-citizens. Because dual citizens have the right to live and work in the UK, they cannot get this permit.

The Home Office has clarified that airlines are now legally required to check for an ETA before boarding. Key points of the new system include:

• Most travelers from Australia must apply for an ETA at least three days before flying.
• Dual citizens cannot apply for an ETA and must show their British passport instead.
• Transiting through a UK airport also requires an ETA or a UK passport.
• The permit is valid for two years once approved.

Options for Impacted Travelers

There are three ways to handle the new travel requirements before the February deadline.

With the UK passport rules change approaching fast, travelers have limited choices. Applying for a new British passport is usually the cheapest option, costing around $190 AUD for adults. Another option is a “Certificate of Entitlement,” but this is much more expensive at $1,182 AUD.

If you have an urgent trip before February 24, you might be able to fly using an emergency travel document. However, after that date, the transition period ends. Thousands of people living in Australia and the UAE who hold British nationality will be affected by this shift.
