I'm an Australian citizen currently in Bangkok deciding where to travel (preferably overland) next.
I just read that for Cambodia I would need to get a full-page visa, but I only have three such pages left and I'm conserving them for when I really have to use them, like China and Mongolia.
I've read that for Laos I can get a visa on arrival when crossing the border and I need to provide a passport photo for it. The photo requirement makes it seem like it would be a full page visa but unlike the info I found for Cambodia, that is not specifically stated.
(Australian passports do not have the possibility of adding extra pages.)
