On page 50 it describes how by 2005 US home prices were on average almost 2.4 times annual incomes, compared with a seventeen-year average of about 1.7 times. How many times the average Australian income are Australian home prices at the moment? I've read from differnet sources recently that the median-priced property in Australia is approximately 7.8 times the average Australian wage!
