The urban footprint in Melbourne is one of the largest in the world because of the low density housing. Do you see any slums in Melbourne? To compare it to a city Bangladedesh, Tanzania or India is like seeing rain and saying the sky is falling in.
I am Malaysian Chinese and my parents made a lot of sacrifices to send me here to study in the 70's. Australia has strict immigration laws and it took me six years of full-time study to qualify for a visa. If you think it's easy you are very much mistaken. It has taken another five years to arrange for my parents to come out.
Fat from being a burden on society, immigrants have made Melbourne what it is - a great place to live. Yes there is a problem with drought and not enough water but the desalination plant will solve that.
