I reckon they should keep cramming immigrants into the big cities. That's where the immigrants want to be, so let em. In developing nations, to improve your lot in life you move from rural areas to the big smoke. So if they come to Oz, they want to improve their lot in life, that's why they come here, so they want to be in the biggest big smoke. Cities are already congested and crowded, so what's it matter piling a heap more in then eh? Don't know what you'se are whinging about?
Us country folk will just take the doctors, since caucasian doctors won't work in the bush anymore, and you city folk can have everyone else. That sounds about right.
See ya's.
