Thai have recently introduced a direct flight to Sydney non stop. The return flight TG 476 however goes via Bangkok and connects within an hour to TG952 to Phuket. This is all a new route. Is TG 952 a dedicated international “domestic” route so you do your on arrival PCR test at Phujer Airport? Otherwise you’d have to stop over in Bangkok for a day I presume.
TLDR : Answer Summary
The recent introduction of a direct flight from Thailand to Sydney includes a connecting flight TG 952 to Phuket. It is unclear if TG 952 operates as a dedicated international route, which would affect the PCR testing protocol at Phuket Airport. It's advised to verify with Thai Airways or the embassy for the latest travel guidelines, especially given the newness of this route.
