Are you my kindred spirit!? :P Thats almost exactly what I do too!

My favourite is when someone apologies for not knowing something or having dumb questions. Apart from “there is never a dumb question” because there usually isn’t, I typically respond with “if everyone already knew how to do everything, I’d be out of a job” which always seems to go down well.

That’s generally the rule - if you’re not sure, declare it, then if it’s not allowed, it’s binned. There are even signs all over the place through Aus (& NZ) customs saying exactly this.

If you don’t declare it and it’s found or it looks like you’ve tried to hide it (wrapped in luggage) then that’s when you get in trouble for it.
