Australians travelling to Thailand in 2026 must complete the Thailand Digital Arrival Card (TDAC) before entry.

This digital version of the TM6 Thailand Immigration Form was reintroduced on 1 May 2025, replacing the previously suspended paper form.

The TDAC simplifies immigration procedures and integrates with Thailand’s digital systems.

This guide explains the transition, the online submission process, and what travellers must do before arriving in Thailand.

So, here's everything you need to know about the Thailand Digital Arrival Card.

The TM6 form, also known as the Thailand Immigration Arrival and Departure Card, is a document required for foreign travellers entering Thailand.

It collects essential details, including personal information, passport details, and accommodation details to assist with immigration control and security monitoring.

Before 2022, travellers arriving in Thailand had to complete a physical TM6 form before passing through immigration.

The form contained two sections; an arrival card to be submitted upon entry and a departure card, which was retained by the traveller and handed over when leaving the country.

However, Thailand suspended the TM6 form for air travellers in July 2022, and for land and sea travellers in April 2024 to ease congestion during the COVID-19 pandemic.

Now, the country is reintroducing this requirement through the Thailand Digital Arrival Card (TDAC), aiming for a smoother paperless process.

From 1 May 2025, all foreign travellers including Australians, must submit their arrival details digitally before entering Thailand.

This new system will replace the paper-based TM6 form and is designed to integrate with Thailand’s E-Visa system, disease screening, and tourist fee collection.

Key features of the TDAC system include:

Thailand temporarily suspended the TM6 requirement to ease congestion at major entry points:

While travellers entering Thailand in 2024 could enjoy simplified entry procedures, the digital TM6 (TDAC) will be compulsory for all foreign visitors from 1 May 2025.

Travellers must complete the TDAC before arriving in Thailand.

The form can be accessed via Thailand’s official immigration website or mobile application.

Travellers can also fill out the form upon arrival at self-service kiosks, but advance submission is recommended for a quicker entry process.

The TDAC system allows corrections if mistakes are made, and airport immigration officers will assist travellers who have not completed the form before arrival.

The new digital TM6 form will contain the same essential details as the paper-based version:

The transition from paper-based TM6 forms to the Thailand Digital Arrival Card (TDAC) is expected to bring multiple advantages:

So, with the Thailand Digital Arrival Card (TDAC) becoming mandatory from 1 May 2025, Singaporean travellers should be prepared for this change.

Completing the form online before arrival will ensure a smooth immigration experience.

The shift to a digital system reflects Thailand’s commitment to modernising its entry procedures, improving efficiency, and enhancing security for tourists.

For those who forget to submit the TDAC before arrival, self-service kiosks and immigration officers will be available to assist at entry points.

As Thailand moves towards a digital-first approach, the TDAC system is expected to enhance the overall travel experience for visitors entering the country.
