Tim Wilson - migration skeptic?

Judith Sloan has been whinging about migration for a while now (a couple of years?)   She thinks there's too many and that they don't really bring economic benefits that others claim.   She has a column in The Australian today making her arguments, in which she seems to concede they may have a small net economic benefit.  

Seems her gripes are exaggerated to me.  Where does she live, Melbourne?   Migrant neighbours bothering her, I wonder?

And then, to my surprise, Tim Wilson comes out in support of her views today:

What is it with these small government, IPA types getting into quasi One Nation migration whinging?

It's very peculiar.
