Where do I put my departure location on the TDAC when transiting through Singapore to Thailand?

The TDAC (Thailand Digital Arrival Card) requires you to specify your departure point when flying to Thailand. If you're flying from Brisbane, Australia, and transiting through Singapore, you should indicate Australia as your departure point. However, ensure you also input the flight number of your final leg into Thailand (from Singapore to your destination in Thailand). Additionally, if you're on a single ticket for the transit, it simplifies the entry process; otherwise, ensure compliance with any customs requirements in Singapore.
