 Hi, Calpez. I really need you to back up these assertions, because as far as I can tell, none of these teams exist at all. The main problem is that none of these places are ""nations"" of any kind, so they can't possibly have ""national"" teams. Just a few examples:
 Australian Indigenous national football team: 2 hits at Google (both Wikipedia)
 Christmas Island national football team: 15 hits, but only from Wikipedia and Wikipedia mirrors
 Cocos (Keeling) Islands national football team: 5 hits. All Wikipedia and Wikipedia mirrors
 I could go on, but I'd be wasting my time. If you want to save this section, please start looking for reliable sources to back up this information. And please bear in mind that Wikipedia has a policy of no original research. You can't just claim that these teams exist because they have their own Wikipedia pages. That's not how things work here.   桜ん坊 "
