Sydney and Melbourne’s populations are projected to explode by 60 to 80 per cent to reach almost 8 million inhabitants each. Perth’s size is set to more than double to 4.6 million within the next 37 years. But politicians, policymakers and the private sector appear unprepared for this radically different future."
