Australia "what countries have you been to and when" is fun, if you have traveled a bit. I thought being to Tunisia during arab spring and China and Russia might be issues! Overall it was hours of paperwork. Wife's grandmothers maiden name kinda crap in there too IIRC. Upside is Citizenship was relatively easy after this (because you have done PR already). Just had to learn some stuff about what happens in Canberra :-).
