You are so far from accurate regarding the Centrelink issue it's not funny.
I'm one of them accused for "ripping off the tax payer" from an Ausstudy payment in 2012 (yep that's right 5 years ago) where I worked part time for 9 months of the year whilst studying then returned to a highly paid previous career for the remaining 3 months once finished studying and without further payment of the study allowance.
These drongos have averaged my income for the year and said I have earned undeclared income whilst receiving the payment and that I now have to pay back all of what I received and the "debt" has been handed over to the collection agency because Centrelink didn't have my current address (why should they? Haven't dealt with them in 5 years) and neglected to call me.
So much for if you have done nothing you have nothing to worry about right?
To add as well this was the only time I've dealt with them.
