Only based on my observations but I couldn't disagree more, out of my social group my friends in the 20's nearly all are on the conservative side, friends in the 30's-40's much more split. My thoughts behind it being the different stages of life, pepole in their late 20's mostly don't care about hospital funding, schooling (assuming that they have already studied) and other similar stuff, they care about the economy, getting a better job and a better start in life. And conservative ideas were pretty popular when ALP governments got thrown out all across the country only a few years back.
I still believe the issues at the moment is that they are all rubbish. My vote will always be able to be brought for the price of a department/ minister of aviation!
