Got this info from Australian Military Attache in Bangkok, hope it assists etc
' The ANF at an ANZAC Day service in a foreign country should be flown in the preeminent position, i.e from the left as the crowd looks at it. The NZ flag should be to the right of that, and then Thailand (or any other host nation).
If, however, one flagpole is taller than the others, this should be in the centre (preeminent position) with the NZ flag to the left and the host nation to the right (as the crowd looks at it).
The ANF (and NZ and host nation’s flag) should be flown at half mast prior to the service, then raised to the mast head on the playing of Reveille after the Last Post. Should be raised slowly so that it reaches the mast head as Reveille is finishing.
