Introduction – reassurance for Australians

If you’re an Australian planning a trip to Thailand and have seen references to the Thailand Digital Arrival Card (TDAC), you’re in the right place.

Thailand now requires international visitors to complete an online arrival card before entering the country. The TDAC replaces the paper arrival cards travellers previously filled out on the plane.

This guide explains what the TDAC is, who needs to complete it, when to submit it, and how Australians can finish the process step-by-step before travelling.


What Is the Thailand Digital Arrival Card (TDAC)?

The Thailand Digital Arrival Card (TDAC) is an online arrival form used by Thai immigration authorities. It replaces the old TM6 paper arrival card that foreign travellers previously completed when arriving in Thailand.

Instead of filling out a form on the plane, travellers now submit their arrival details online before entering the country.

The TDAC collects basic information including:

  • Your personal and passport details
  • Your travel information and arrival date
  • Your accommodation in Thailand
  • A short declaration relating to travel and health information

The system allows immigration officers to process arrivals digitally rather than collecting paper forms.

The TDAC is not a visa and does not change visa-exemption rules for Australians. It is simply a required arrival declaration.


Do Australians Need to Complete the TDAC?

Yes. Australian passport holders entering Thailand must complete the TDAC before arrival.

This applies to travellers entering:

  • By air
  • By land
  • By sea

You must complete a TDAC if you are visiting Thailand for:

  • Tourism
  • Business travel
  • Visiting friends or family
  • Any entry that requires passing through immigration

Children and infants must also have a TDAC. Parents or guardians can complete the form on their behalf.

The only common exception is transit passengers who remain airside and do not pass through Thai immigration.


When Australians Must Submit the TDAC (72-Hour Rule Explained)

The TDAC must be submitted within 72 hours (three days) before arriving in Thailand.

This timing window includes the day of arrival.

Example:

  • If your flight lands in Bangkok on Saturday, you can submit the TDAC starting Wednesday.
  • If your arrival is Wednesday, submission can begin on Sunday.

Submitting too early may result in an invalid submission, so it is best to complete the form one or two days before departure from Australia.

Important timing notes:

  • The TDAC is valid for one entry only.
  • If you leave Thailand and re-enter during the same trip, you must submit a new TDAC for each entry.
  • There are no automatic reminders, so travellers should set their own reminder before flying.

What Information Australians Need Before Completing the TDAC

Before starting the form, gather the following details so the process can be completed quickly.

Most Australians finish the TDAC in three to five minutes once these details are ready.

Open the official TDAC website in your browser and start a new arrival card submission.

Check the website address carefully to ensure you are using the official system.

Step 2 – Select language and start the form

Make sure the arrival date falls within the 72-hour submission window.

Step 5 – Enter accommodation details

If staying in multiple locations during your trip, only the first accommodation is required.

Step 6 – Complete the declaration section

Answer the short declaration questions and confirm that your information is correct.

Step 7 – Review and submit the form

Carefully check your details, especially:

  • Passport number
  • Name spelling
  • Arrival date
  • Flight number

Submit the form once everything is correct.

Step 8 – Save your confirmation

After submitting the TDAC, you will receive a confirmation email with a QR code or reference number.

Save the QR code on your phone or print a copy as backup.


What Happens After You Submit the TDAC

After submitting the TDAC:

  • Your details are stored in Thailand’s immigration system.
  • The information is linked to your passport.
  • Immigration officers can retrieve your record when you arrive.

On arrival in Thailand you may be asked to show your QR code confirmation, either on your phone or printed.

You will then proceed through the standard immigration process, including passport inspection and entry stamp.


Common TDAC Mistakes Australians Should Avoid

Avoid these common issues:

Submitting too early
Submitting more than 72 hours before arrival may invalidate the form.

Using unofficial websites
The TDAC is free. Third-party websites may charge unnecessary fees.

Passport spelling errors
Names and passport numbers must match your passport exactly.

Incorrect arrival date
Ensure the date reflects when you actually land in Thailand.

Not saving the QR code
Keep the confirmation accessible on your phone or printed.

Forgetting to complete a new TDAC for re-entry
Each entry into Thailand requires a new submission.


What Happens If You Arrive in Thailand Without Completing the TDAC?

If you arrive without completing the TDAC, airport staff may ask you to complete the form before you proceed to immigration.

Some airports provide kiosks or Wi-Fi access to allow travellers to submit the form on arrival.

However, completing the TDAC at the airport may cause delays, particularly when arrival halls are busy.

Completing the form before leaving Australia is the simplest approach.
