Maybe it's the fault of the loosening up of the passport system, that
allows people to be dual citizens.

Now there are people living here and then over there and nobody knows
what the hells going on or where people are.

This was the fault of governments bowing to the pressure of people
who wanted dual citizenship.
It's a bit like the problems the free borders are now causing in Europe.

No accountability for the movements of people or what the heck they
are doing in your country, or is it back in their old country, fighting a war
with the other country they share dual citizenship with.
Just chaos, and non accountability.

Cherful,

I don't believe that dual citizenship should be allowed under any circumstances. Frankly, I would not trust a dual citizen as far as I could kick him/her. If you don't want to be Australian, don't come here.

CHERFUL - I could be wrong but don't think so, If they were Dual citizens that would have been stated or one would assume they would have used the Australian one to register not the foreign one.
