How big is too big? Australia is taking unprecedented numbers of migrants – permanent and temporary. We will examine whether a bigger Australia is really a better Australia. We talk to migrants, business groups, economist, demographers, politicians and a mayor about Australia’s fast pace growth. Polls show Australians are resistant to fast growing migration. Are they? Is it really because of the sustainability – or is it something more? Is population growth key to economic growth and the prosperity of the country? What do migrants think about the population and migration discussion. We’ll talk about whether there are hints of social problems arising in our fastest growing cities.
