I did a trip to Melbourne mid December and came back late January. Made sure l had Morprom, vaccine certificate and yellow vaccine passport.
To get into Australia all l really needed was the Thai Vaccine Certificate. Had to upload online to get Australian Travel Declaration prior to flying. Nothing more required.
Later l took same Thai Certificate to a vaccination point in Melbourne, in my case a pharmacist, and they entered my two Thai Astrazenica shots into the Australian Medicare online system together with the Moderna booster that l got in Aust.
All very easy and straight forward.
Wish l could say same about trying to get Aust Moderna booster added to Thai Vaccine certificate and Morprom.
Have tried to two local hospitals that are vaccination points and both say sorry, we don't recognise foreign vaccine certificates. Defies logic because Thailand accepted it to issue my Thai Pass before entering Phuket Sandbox in January.
If anyone can tell me if they have successfully updated Thailand Vaccine records and how, l would be most appreciative
