Do Australians Need an ESTA for the USA? Your 2026 Guide

That’s the case with the US ESTA. This travel authorisation was introduced in 2008 and became mandatory in January 2009, making it one of the earliest electronic travel authorisations of the current era.

The ESTA is not a visa. In fact, it’s intended for travellers who don’t need visas to enter the US. If you’re an Australian citizen, that’s probably you. So if you’re planning a trip to the United States, chances are good that you need an approved ESTA.

Let’s take a look at the latest requirements for the US ESTA in 2026. We’ll look at exactly who needs it, how to get it, and what it allows (and doesn’t).

What Is ESTA?

ESTA, short for Electronic System for Travel Authorization, is an automated system the US government uses to decide whether travellers are eligible to visit the United States under the Visa Waiver Program.

It’s not a visa, so you don’t need to make an appointment at the embassy or sit an interview explaining your employment history and family status.

Instead, it’s an electronic authorisation that’s linked to your passport. Airlines can see your ESTA status when they scan your passport before you get on a flight. Generally, you won’t be allowed to board a flight to the US unless you have one.

Luckily, getting one isn’t that difficult, and it’s certainly a lot easier than getting a visa. First, you’ll want to work out if you need one (you probably do), and then we’ll look at how to get it.

Do Australian Citizens Need an ESTA to Visit the USA?

Yes. The ESTA applies to citizens of every country in the US Visa Waiver Program, a group of around 40 countries whose citizens can visit the US without a visa. That includes Australia.

Under the Visa Waiver Program, Australians can stay in the United States for up to 90 days without a visa. You can visit for tourism, to see family and friends, or for some business activities like attending meetings or conferences, but not to work. The 90 days can’t be extended, and quick side trips to Canada, Mexico or the Caribbean generally count towards your total, so don’t treat a weekend in Cancún as a reset button.

Because the ESTA is not a visa, it’s important to remember that it does not guarantee you entry. US Customs and Border Protection (CBP) officers make that decision when you arrive. The ESTA is just the authorisation you need to travel to the country in the first place, not a right to enter once you get there.

How to Apply for an ESTA from Australia

You probably won’t be allowed on the plane without an ESTA, so it’s a good idea to apply for one as soon as you know you’re going to travel. You don’t need to show proof of travel to get one, so it makes sense for this to be one of the first pieces of paperwork you sort out for your trip.

There are two official ways to get an ESTA: the US government website or the ESTA Mobile app. However you choose to do it, the steps are virtually the same.

Step 1: Gather Your Documents

You’ll need:

• A valid Australian passport with an electronic chip (all standard Australian passports issued since 2005 have one)
• An email address
• Your home address and contact details
• An emergency contact
• A credit or debit card
• A photo of your face

You may also be asked to provide details about your employment, your parents, previous travel, and where you’ll be staying in the US.

It’s worth knowing that CBP has proposed some bigger changes to ESTA, including making five years of social media history mandatory, requiring a selfie with every application, and moving applications to the app only. These were still proposals at the time of writing, so check the official ESTA website for the current requirements before you apply.

Step 2: Visit the Website or Use the App

Go to esta.cbp.dhs.gov and select the option to create a new application. Alternatively, download the ESTA Mobile app from the Google Play Store or the Apple App Store.

Be careful with search results here. There are plenty of unofficial websites that look very official and charge a hefty "service fee" on top of the real cost. If the web address doesn’t end in .gov, close the tab.

Step 3: Complete Your Application

Follow the prompts to enter your personal information, passport details, and travel information. You will also be asked about previous immigration violations, criminal history, and whether you have travelled to certain countries in the past.

These countries are Cuba, North Korea, Iran, Iraq, Libya, Somalia, Sudan, Syria, and Yemen. If you’ve visited one of them since March 2011 (or Cuba since January 2021), you’ll generally be ineligible for ESTA and need to apply for a visa instead. The same applies if you’re also a citizen of Cuba, Iran, Iraq, North Korea, Sudan or Syria. These are Visa Waiver Program rules rather than ESTA-specific ones, so they’re not new.

Step 4: Pay the Fee

If you pass the screening questions, you’ll be asked to pay the application fee. The ESTA fee roughly doubled in September 2025, and it’s now around US$40, which works out to roughly A$60 depending on the exchange rate. If your application is denied, you’re only charged a small processing portion of the fee.

Step 5: Wait for Approval

In some cases, your application will be approved within minutes. In others, you’ll have to wait longer. US authorities recommend applying at least 72 hours before you’re due to depart. But because the ESTA has a long validity, it’s usually best to apply as soon as you decide to travel. There’s really no advantage to waiting until the last few days.

Once your ESTA is approved, it will be linked electronically to your passport. You don’t need a special stamp or a printout to use it, although saving a screenshot of the approval page never hurts.

While you’re sorting your travel authorisation, it’s also worth thinking about how you’ll stay connected in the US. You can avoid expensive roaming charges by grabbing a travel eSIM before you fly. Install it at home, and it connects to a local network once you land.

How Long Is an ESTA Valid?

Your ESTA is valid for up to two years. However, because it’s linked to your passport, it expires when your passport does. So if your passport expires within those two years, you’ll need to reapply for an ESTA with your new passport. The same goes if you change your name or gender, or if your answers to any of the eligibility questions change.

Within that two-year validity period, you can take multiple trips to America on the same ESTA. That’s why it’s a good idea to apply as soon as you plan to travel, since it covers you for a long time.

Do Australians Need an ESTA for Transit Through the USA?

Yes. If you don’t have a visa, you’ll need an ESTA to enter the US for any reason, even if you’re just changing flights there.

This is worth remembering, because lots of countries with similar electronic travel authorisations, like the UK, let you skip them as long as you stay in the secure transit area of the airport. You change planes without passing through passport control, so you don’t need the authorisation.

That’s not the case in the US. Even if you never leave the airport, you will need an ESTA. US airports don’t have airside transit, so every international passenger goes through immigration, even on a tight connection. Your airline should flag this if you book a ticket to Canada, Mexico or South America with a layover in the US, but it’s always worth checking yourself.

Entering the US with an ESTA as an Australian

Australian citizens generally don’t need a visa for short tourist visits to the United States. But they do need authorisation to travel through ESTA, even if they’re simply making a connection. And since it’s valid for up to two years, it’s worth getting as soon as you start planning your trip.

Getting the ESTA is a straightforward process for most people. And while you’re getting your paperwork in order, it’s also worth thinking about your phone. Grab a USA travel eSIM from ZenSim and you’ll be online with a local network from the moment you land, potentially saving a fortune in roaming fees.
