Like most above have been mentioned but also Australian Bureau of Statistics can be very useful (even though it may be not so user friendly). You could see where the incomes are increasing, what demographics are changing!
Sounds about right. Being new to this forum, do people share their models and approach? I'd keen to learn the right questions to ask in order to choose property. I have started to develop my own, but I'm sure someone who has been doing this for some time has a far better model and approach!
