The good news is that Trump keeps posting tweets referring to Australia's immigration policies, take a look at Trumps twitter and recent media uploads..

Here in Aus our closest neighbours New Zealanders, those from South Pacific, ( like Mexico and Canada to the USA) have full immigration rights, they can come here and work, get full government benefits, free health care, free education, anytime they want.
The only difference Government rights and benefits wise between an Australian and an New Zealander living in Australia, is the right to vote in Australian elections and vice versa. 23% of NZ's population live in Aus, 1 in 6 Maori, live in Australia ;)
Time to invite your Mexican family ;)
