Senator GALLAGHER (Australian Capital Territory) (14:39): My question is to the Minister representing the Treasurer, Senator Cormann, and relates to housing affordability. Is the minister aware that on house price to income ratios Sydney is now the second most unaffordable city in the world and Melbourne the fourth? What is the Turnbull government doing to address housing affordability and ensure that more Australians are not permanently locked out of the housing market?
