I'm about to travel through Australia, and I'd like to use my American TSA-openable locks on my luggage. I'm not sure if I should, though, or if I'm just inviting Australian authorities to damage my luggage in order to inspect it. (I'm travelling from Papua New Guinea back to the USA via Australia.)
On my journey here, I put these locks on my suitcases, and when I transited through the Philippines, I discovered later that the Philippine airport staff had intentionally cut through part of the zippers on a suitcase in order to get around the lock and inspect the contents. Thankfully, I can still lock it via a part of the zippers that weren't designed to be used that way, but if my suitcase has to be opened by force again, it will become impossible to even twist-tie shut, and thus effectively unusable. I'd like to avoid this happening, especially since my trans-Pacific flight would happen after such an incident.
I suppose there's an additional consideration if the PNG airport security people decide to inspect the bag before it goes anywhere.
Should I, then, lock the suitcase? Or should I just twist-tie it shut, and hope no one in PNG (or elsewhere) decides to pilfer things from it?
