I think they are gone be treated as foreigners (same as ABC's now are treated) but they gone have a huge advantage as understanding and having knowledge of both cultures in their future lifes with the right education.

When walking over Rodondo beach I always have a hard time for not getting or hiding my boner. 

From the stories I have heard, mixed kids here are a target for jealousy within the school system.  Most of them become the teacher pets because of their looks (and intelligence) and some of the other kids don't care for that.  Think of what high school was like for most of us. Sticking out wasn't really a good thing.  And here, that sticking out is 10 fold.

I have 2 mixed boys (3 years old) and they get tons of attention.  Even in preschool, they were harassed by some of the other kids just because they were different.  Now they are going to an American school here and they fit in much better.

for a lot of diffrent ressons.
In my wifes small city it is not as bad as I thought for them but there are more benifts staying in Aus for them.
