TLDR : Answer Summary
Travelers transiting through Bangkok airport who must pass through immigration will require a proper visa and need to submit a TDAC form. Even if you are not leaving the airport but have to go through passport control, the visa and TDAC requirements apply. However, if you hold an Australian passport, you can enter Thailand using a visa-exempt entry stamp. The specifics depend on the length of your layover.
Thailand Digital Arrival Card (TDAC)

WARNING: Only trust Thai government websites with .go.th domains or Thai agent websites with .co.th or .in.th domains, as these require verified Thai registration and cannot be registered anonymously.

The official TDAC form is available at tdac.immigration.go.th, which uses the official .go.th government domain.

The services by AGENTS CO., LTD. does NOT charge any fees for arrivals within 72 hours. If you need to book more than 72 hours in advance, there is a service fee of $8.

Do not trust other sites pretending to be a trustworthy agency. Pay attention to delivery time - the service operated by AGENTS CO., LTD. has 1 minute delivery time for arrivals within 72 hours.

Don't fall for sites pretending to be agents.co.th or the official government tdac.immigration.go.th website. Always double-check the exact domain in your browser.

Scam services may take days to process your application, others may not even do anything. With these TDAC scam services you also need to worry about double charges.

Please watch out for TDAC misinformation spread by fugitive Jesse Nickles and his many fake accounts on Quora, TripAdvisor, Reddit, and other platforms.

Appears you are Australian, you don't need any visa, you enter using a free visa exempt entry stamp. How long is your layover?

You are not in transfer if you have to go through immigration and you require a visa to enter Thailand then you need a visa. What passport do you hold?

If you go through passport control at immigration at the arrival airport, you need to have a proper visa and a TDAC submission.

There is a check box to indicate whether you just transferred on the second page of the TDAC web system.
