if this alien becomes pregnant by an American, the baby is automaticaly an American citizen but at any time the mother can be deported back to her country unless she is married to the father of the baby or to a u.s citizen.
Only if the baby has reached the legal age, i believe is 21

If the baby is born in the US it's an automatic US citizen. Regardless of where it's born, the father is responsible to provide child support if the mother should request it. The father may also request custody and visiting rights, but sorting out that kind of thing internationally, long-distance can be a huge headache.
In American law, yes. I think it's also true of Australian law. The Australian must register the baby as Australian born overseas to Australian parent - it doesnt say if the parent must be the man or the woman. I don't remember if the law mentions marriage. If born in Australia and one parent is Australian, then it should be automatic citizen.
only if the baby was born in the us
Keep it in your pants next time... But don't worry. Tell her not to come and she'll sue you for child support eventually.
