Dont forget apart from kids, there is an awful lot of retired people in there too including self funded retirees, and others who dont "work " as in paid employment but who dont necessarily draw welfare benefits such as stay at home mums, dads etc and these people are not unemployed as such.
I'm sure the figures would be fairly accurate, because lets face it if the actual figures were higher than that then the opposition would be falling over themselves to make a big deal about it with the Gillard government
