UK ETA vs Canada eTA vs Australia ETA: Complete 2026 Comparison

As more countries introduce digital travel authorisation systems, travellers often find themselves navigating multiple electronic permit requirements for different destinations. The UK ETA, Canada eTA, and Australia ETA are three of the most commonly required electronic travel permits for international visitors, and understanding the differences between them is essential for planning multi-destination trips.

This comprehensive comparison guide breaks down the key differences and similarities between these three systems, helping you understand what each requires, how much they cost, and what they allow you to do.

Key fact: The UK ETA costs £16 per application, is valid for 2 years or until your passport expires, and allows unlimited visits of up to 6 months each. Citizens from 48 eligible countries must obtain an ETA before travelling (Source: GOV.UK).

Overview: What Are Electronic Travel Authorisations?

Electronic Travel Authorisations (ETAs) are digital permits that allow citizens of visa-exempt countries to travel to specific countries without obtaining a traditional visa. They serve as pre-screening tools that verify a traveller’s identity and assess security risks before departure. While the underlying concept is the same, each country implements its system differently.

The three systems compared in this guide are:

• UK ETA — The United Kingdom’s Electronic Travel Authorisation, fully enforced from February 2026.
• Canada eTA — Canada’s Electronic Travel Authorization, in operation since November 2016.
• Australia ETA — Australia’s Electronic Travel Authority (subclass 601), one of the oldest electronic travel permit systems, operating since 1996.

Side-by-Side Comparison Table

UK ETA: Detailed Analysis

The UK Electronic Travel Authorisation is the newest of the three systems. Introduced in November 2023 for Gulf Cooperation Council nationals and expanded globally by February 2026, the UK ETA is part of the government’s broader digital border initiative.

Key Strengths

• Generous stay period — Up to 6 months per visit, the longest of the three.
• Modern application — Available through a dedicated mobile app with biometric verification.
• Part of digital border — Integrated with the UK’s comprehensive eVisa system.
• Two-year validity — Good balance between cost and validity period.

Key Considerations

• Security questions — The UK ETA includes detailed security screening questions that are more comprehensive than the Canada eTA.
• Transit requirement — Even transit passengers must hold a valid UK ETA.
• Photo requirement — The app requires a biometric photo taken during the application, which can cause issues if not done correctly. See our guide on UK ETA photo requirements.

Canada eTA: Detailed Analysis

Canada’s Electronic Travel Authorization has been operational since November 2016, making it well-established and proven. It applies to visa-exempt foreign nationals flying to or transiting through Canada.

Key Strengths

• Cheapest option — At just CAD $7 (approximately USD $5), it is the most affordable of the three.
• Longest validity — Valid for 5 years, offering excellent value for frequent travellers to Canada.
• Fast processing — The vast majority of applications are approved within minutes.
• Simple application — Straightforward online form with fewer security questions than the UK ETA.

Key Considerations

• Air travel only — The Canada eTA is only required for air travel. It is not needed when entering Canada by land or sea from the United States.
• No mobile app — Application is website-based only, unlike the UK and Australia systems which offer dedicated apps.
• US citizens exempt — US citizens do not need a Canada eTA (they are exempt from both visa and eTA requirements).

Australia ETA: Detailed Analysis

Australia’s Electronic Travel Authority is the pioneer of electronic travel permit systems. First introduced in 1996, it was one of the first countries to implement a fully digital pre-arrival screening system.

Key Strengths

• Proven system — Nearly three decades of operation have made the Australian system highly reliable.
• Quick processing — Most applications are approved instantly or within 24 hours.
• Mobile app available — The Australian ETA app provides a convenient application experience.

Key Considerations

• Shortest stay — Maximum stay of 3 months per visit, compared to 6 months for the UK and Canada.
• Shortest validity — Only valid for 1 year, compared to 2 years (UK) and 5 years (Canada).
• Limited eligibility — The Australian ETA is available to passport holders from only about 40 countries, compared to broader eligibility for the UK and Canada systems.
• Separate transit visa — Unlike the UK ETA, Australia has a separate transit visa requirement.

Which Countries Need Which Authorisation?

The eligibility requirements differ for each system. Here is a general overview of how major nationalities are affected:

EU Citizens

EU citizens need a UK ETA to visit the UK (post-Brexit requirement since 2025). They also need a Canada eTA for flights to Canada. Most EU citizens are eligible for the Australia ETA. For specific guidance on EU citizens and the UK, see our guide on UK ETA for EU citizens.

US Citizens

US citizens need a UK ETA to visit the UK. They do not need a Canada eTA (US citizens are exempt). They do need an Australia ETA for visits to Australia. For more details, see our guide on UK ETA for US citizens.

Japanese Citizens

Japanese citizens need all three: a UK ETA, Canada eTA, and Australia ETA for their respective destinations.

Cost Comparison Over Time

When comparing value for money, consider the validity period and how often you plan to visit:

All three systems offer excellent value compared to traditional visa applications, which can cost hundreds of dollars and take weeks to process.

EU ETIAS: The Fourth Player

It is worth noting that the European Union is also developing its own system called ETIAS (European Travel Information and Authorisation System). Once launched, it will require visa-exempt travellers (including UK, US, Canadian, and Australian citizens) to obtain electronic authorisation before visiting the Schengen Area.

What Happens If You Are Refused?

Each system handles refusals differently, and understanding your options is important before you travel:

UK ETA Refusal

If your UK ETA is refused, you can apply for a standard UK visitor visa through the full visa application process. This allows you to submit additional documentation and provide a more detailed explanation of your circumstances. There is no formal appeal process for ETA refusals, but administrative review may be available. For more details, see our guide on what happens if your UK ETA is refused.

Canada eTA Refusal

A refused Canada eTA means you will need to apply for a temporary resident visa (TRV) to visit Canada. The TRV application is more detailed and requires supporting documentation, but it provides an alternative pathway. You can also request reconsideration of the eTA decision.

Australia ETA Refusal

If your Australian ETA is refused, you can apply for a visitor visa (subclass 600) instead. This is a more comprehensive application process that allows you to provide additional evidence of your eligibility to visit Australia.

Travel Tips for Multi-Country Trips

If your travel itinerary includes visits to the UK, Canada, and Australia, here are practical tips to manage your electronic travel authorisations:

• Apply early — Submit all applications at least two weeks before your first departure date to allow time for processing and any potential delays.
• Use the same passport — Ensure you apply for all authorisations using the passport you will travel with. If you hold dual nationality, choose one passport and use it consistently.
• Keep confirmation records — Save approval emails and screenshots. While all three systems are linked electronically to your passport, having confirmation provides peace of mind.
• Check validity dates — Before each trip, verify that your authorisations are still valid. The Australia ETA (1 year) may expire before the UK ETA (2 years) or Canada eTA (5 years).
• Budget for all fees — The combined cost of all three authorisations is approximately USD $31, which is significantly less than a single traditional visa for any of these countries.
• Know the rules — Each country has different rules about what you can and cannot do. None of these authorisations permit work, but the maximum stay periods differ (6 months UK, 6 months Canada, 3 months Australia).

The Future of Electronic Travel Authorisations

Electronic travel authorisation systems are becoming the global standard. In addition to the UK, Canada, and Australia, several other countries and regions are developing similar systems:

• EU ETIAS — The European Travel Information and Authorisation System will cover 30 European countries in the Schengen Area.
• New Zealand NZeTA — Already operational, covering visitors to New Zealand.
• India e-Tourist Visa — India has implemented its own electronic visa system for tourist visits.
• South Korea K-ETA — South Korea’s electronic travel authorisation for visa-exempt visitors.

As these systems become more widespread, international travellers will increasingly need to plan ahead and budget for multiple electronic authorisations as part of their trip preparation. The good news is that all these systems are designed to be quick, affordable, and user-friendly compared to traditional visa processes.

Frequently Asked Questions

Can I use a UK ETA to visit Canada or Australia?

No. Each electronic travel authorisation is specific to its issuing country. A UK ETA only allows travel to the United Kingdom. You need separate authorisations for Canada (eTA) and Australia (ETA).

Do I need all three if I am visiting all three countries?

Yes. If your itinerary includes the UK, Canada, and Australia, you will need to apply for each country’s electronic travel authorisation separately. Plan ahead and apply for all three before your trip.

Which system is easiest to apply for?

The Canada eTA is generally considered the simplest, with a straightforward online form and minimal documentation. The UK ETA requires a biometric photo and more detailed security questions. The Australia ETA application is relatively simple but has stricter eligibility criteria.

What happens if I am refused one but approved for others?

Each system operates independently. Being refused a UK ETA does not affect your Canada eTA or Australia ETA applications, and vice versa. However, the refusal will be on your record and may need to be declared on future applications to other countries.

Are children required to have their own authorisation?

Yes, for all three systems. Every traveller, regardless of age, must have their own electronic travel authorisation linked to their own passport.

Conclusion

The UK ETA, Canada eTA, and Australia ETA all serve the same fundamental purpose — pre-screening visa-exempt travellers before they arrive. While the systems share many similarities, the differences in cost, validity, maximum stay, and application requirements can affect your travel planning.
