Sorry mate, anecdotes are not evidence, no matter how many of them you have.
Here's data up to fairly recently on a bunch of countries, you will find a range of results under the prices vs average income. Australia is in the top range of all indicators. Japan, South Korea, Singapore have the lowest current ratios but a bunch of EU nations are on fairly average ratios too.
http://www.economist.com/blogs/dailychart/2011/11/global-house-pricesHere's your women in the workforce for Australia. A slow, steady rise, nothing that would explain sudden, dramatic price increases like those seen in the late 90's, early 00's.
Look I'm not saying that people can't buy property. The average (or more precisely, the median) wage is exactly that; half of people will be above the median and relative to their income property will look like not such a bad deal. If your wage is above that line, it's fairly good chance that you are going to have friends, family and associates also above that line - and in your little world it will look like it's not such a big deal. For the 50% of people below the line, poor government policy has failed to
either keep property speculation to a minimum
and/or keep wage growth in line.
You/other people are much too willing to throw your hands in the air and call the death of affordable property (or any other ultimately temporary political/economic situation). The world economic climate is a major contributor but there are still strong actions our government could potentially take. Instead they fail to act in the positive - which in my opinion means they continue to act in the negative through inaction - by failing to change policies that exacerbate the situation (easily within their power) they are continually deciding to worsen the problem. I'm going to get political here and say the reason why is because many of the politicians in power and those that influence them are all high-income property investors and from their perspective, and the perspective of those that they choose to listen to, the problem is not actually a problem.
You will see conservative media constantly try and reinforce this perspective with push-pull housing bubble articles (article today says yes, housing bubble, the one tomorrow will say no), blaming the victim (eg smashed avocado brunches and young people generally being terrible with money - not like responsible boomers in the 80's), cherry-picking data (here, look at this one single person who is under 30 and has 10 properties! tomorrow we will have found one more to show you!).
