Depends on how you define 'shortage'. If you define shortage as demand exceeding supply, then there's definitely a shortage in areas where you live such as Mosman...not so much in other areas like Penrith etc..
Australian lenders have never ever done stupid NINJA loans so I don't think we'll have the same widespread problems that the US did. Particularly these days if you have no income you can't even borrow money on a 10% LVR.
