I married my wife over there last year and was not asked for this. Had they done so I would have gladly handed them my Australian Federal Security Clearances. If you have nothing to hide then I don't see any issues.
Oh ok well that makes it easy for us then. I can just take a pic on board the aircraft with my phone or just fill in 2 of the bloody things and then do the rest from there. She is in Prachinburi but I have to go straight into Sukomvit first when I get there so it should be easy.
