There is some confusion about debt. Government Debt was pretty stable until 2008 when it suddenly from under $100bn to $430bn in 2013 (now stands at $21,000 per head of population).
The link below is a good guide to what is roughly happening.

The real news is that Total Australian Debt is close to $4.8 trillion at present, up from about $1.5 trillion in the early noughties, that equates to $212,0000 per head of population.
Politics aside, all debt needs to be reigned in, we deal with it now in a sensible manner or just weight until the bubble bursts.
