Sydney comes in second last on the affordability index.

No surprise there. It is the most overrated expensive rather untidy collection and nothing to be proud of. http://www.demographia.com/dhi.pdf It is really quite sad as I am a Sydney sider born and bred and my ancestors journed as free settlers to Australia in the 1840s and lived in close quarters to the City and finally settled in Paddington. The houses still stand.
