My wife was the main income earner, and I was the stay-at-home parent raising our three children. When my wife left, returning to Japan and kidnapping our three children in the process. I was later contacted by Centrelink (Family Allowance), stating that I personally owed them $10,000 in overpayments. I have asked them in writing (emailed their Centrelink site) for an independent assessment on several occasions which is apparently my legal right, but they have never allowed this to progress. I was only contacted by one of their staff, who stated that if I stopped paying regularly, they would place my debt in the hands of a debt collectors. I have been paying the debt off regularly every week ($50). and have reduced the debt to approximately $7,000. I now have been contacted again by Centrelink, stating that since I do not have a written agreement of repayments, and that they will be looking to take any future tax refunds. I have been paying regularly, yet they threaten me this way? They also threatened, that if I stop regular payments, they will put it into the hands of a debt-collecting agency which will charge me interest? Bully boy tactics at best, I say. Since the family allowance was based on my wife's income, and I was the stay-at-home parent, why is this debt solely mine? Initially, when we first asked for family allowance on our return to Australia, i believe that I used my medicare number as my wife dod not have one yet. I have never had this debt fully explained to me, or any copies of paperwork relating to this debt, so I cannot challenge anything. How do I obtain an independent and fair assessment of my apparent debt, without Centrelink stopping this, as they have done before?
