Things have been crazy for a long time, but I am actually optimistic for Melbourne specifically - the construction rate is up and the state government has been decreasing the power local governments have to block or delay development. If this continues, housing affordability should improve. My main concern is that a change of government may put an end to it, but I hope not.
