Sydney and Melbourne have definately been the growth stories of the last 2 years. Whereas Brisbane has been sluggish in comparison. There's probably many factors that have contributed to this but the softening in the mining sector and the public service cuts by the Newman government have put a dampner on confidence. 

While Sydney has been going strong the rate of growth is above the long term trend which suggests at some point there will be a market correction. With a median of $850,000 and average yields of only 3.7% that's a fairly substantial shortfall for investors to fund.
Melbourne is sitting at $613000 with yields of 3.3%.

With Brisbane sitting at $485,000 average yields of 4.6% and interest rates now sitting at 4.5% and lower we feel its only a matter of time before some catch up occurs.

The key factors will be a return of confidence and improvement in the jobs figures. But don't think the market isn't moving up. It still grew 5.1% for the last 12 months. 

So as always it will be the ones that move early while others sit on the fence that will maximise their upside.
