I know this is Victoria but reading this is remarkably similar to what seems to be happening here in Adelaide and it's suburbs, particularly the 'sitting back and approving' - yes the blocks are larger on the outskirts, the blocks are cheaper too but like the article says this doesn't actually help the economy. Is it sustainable? Should I even be allowed an opinion given that I am a migrant (thus adding to the demand for housing) and choose to live out of the city because we got more house for our money?
