I have always been aware that I have to report to centrelink and I have always intended to and the money will come straight from my supplement to pay it back (it is only a very small amount like $300). I am just confused about the tax side as I have only ever been employed rather than working for myself and as it is such a small amount and I still do not earn enough to pay any tax I was unsure. I will call the ATO then lodge an online tax return today.
