Another problem I just noticed - it seems your spending figures include more than just benefits paid in cash. Eg http://www.aihw.gov.au/expenditure-faq/ says
"In 2010-11, Australian Government and state and territory government welfare spending was estimated at $119.4 billion - $90 billion (75%) was in cash payments (including unemployment benefits) and $29.4 billion (25%) was for welfare services."
So to make your case you'd need to dig up figures about how much the administrative overhead related to the cash benefits is.
