How did you go katie? I have voluntarily dobbed myself in for the same thing. Under reported for 18 months. I can pay back 10k as soo as I know the debt I gave centrelink my payslips from my work for the whole time the other day and I’m waiting to hear what the debt is so I can whack $10k on it. I am afraid of being prosecuted and what it will do to my children (if I go to jail) and my career. I didn’t know that I could be prosecuted. True, I am a dickhead. I know.
