I managed to get a little yellow highlighter on the biodata page of my passport, which rubbed off from airline staff highlighting my boarding gate number on the boarding pass. I assume i'll have to go down to the Aus embassy to apply for a new one, as I might have some trouble down the line due to the damage. Once I receive my new passport, do I need to go to immigration to transfer my visa (tourist visa), or do i just show both passports when flying out?
I'm also flying to Chiang Mai next week, i'm assuming there wouldn't be any issues with using my other passport (British) to travel since I won't have my Aus one? Similarly, anyone have experience on the processing times, it says 15 working days, and I fly out in 18 working days, so not sure if that is cutting it fine in case it sometimes takes longer.
