The Australia Institute should lift its game and look at the 2012 data instead of 2012.
Look here http://www.oecd-ilibrary.org/economics/government-debt_gov-debt-table-en
Debt as a percentage of GDP has grown 50% over 2 years. Is that good economics?
Why the reliance on old data? Does it suit the left leaning think tanks funding and other agendas?
Our nett debt is not so super either but reflects the general demise of government who put cash into the failing segments of their economy to maintain the status quo.
