Oversupply of Brisbane Apartments Coming?

BIS predicts an oversupply of apartments in Brisbane beyond 2014.  See article.  There was a similar story in the AFR on Monday, 11 February.   In my view, BIS' predictions often don't come true.  In March 2008, BIS predicted that the Brisbane market would perform the best.  Wrong.  In August 2008, BIS said there would not be a big decline in prices of Brisbane real estate.  Wrong.  So why should their most recent prediction be any better?  How can BIS accurately predict demand for apartments in Brisbane in 2015?  See also this prior post.
