There's a piece over at the Guardian giving figures of how the property market has been driven upwards by investors in Sydney in the last year or two. It's a data-driven article, so lots of graphs for you to look at. Investors have reignited the fire under Sydney and Melbourne house prices There are also a couple of similar articles on income and wealth distribution. Australia's rich are getting richer. Everyone else is stagnating The rich are getting richer – and their wealth is safe as houses One thing that struck me is that the median before-tax household income is around $81K. The Housing Affordability thread on Bassanesse's article pegged it at $117K after tax. That makes affordability look much worse.
