I can't figure this out myself. I could swear that budget accounting is designed to be as unreadable and incomprehensible as humanly possible. Take a look at http://www.budget.gov.au/2016-17/content/bp4/html/05_art-16.... and scroll right to the bottom. Taken at face value, this seems to suggest total actual appropriations just for the Treasury portfolio were $765bn in 2015-16. Given this equates to about 43% of nominal GDP in 2015, there must be something else going on here that I''m missing.
