Interesting to hear our Treasurer Joe Hockey taking a swipe back at his own department to alleviate concerns about a housing bubble in Sydney and Melbourne. Mr Hockey is happy to leave it to market forces and cites the real issue is supply. The response was to comments made by Treasury Secretary John Fraser to a Senate Committee this week stating that the Sydney and Melbourne markets were in a bubble. Does this mean the Government will be looking at incentives to encourage an increase in supply and address affordability issues?
