Do I need a COVID-19 test to board flights from Thailand to Australia?

The original poster inquired about the need for a COVID-19 test for their flight from Thailand to Brisbane via Manila. Responses indicated that a COVID-19 test is not required to exit Thailand, but travelers should confirm requirements for entering Australia and any countries in transit. It was also noted that international flights are banned until May 30, and travelers should check with the Australian embassy and their airline for the most current travel restrictions.
