Hi. Centrelink today (23 July 2015) sent me a letter stating that I had been overpaid Family Tax Benefit (FTB) in 2001/2002 and that I now owe them $2092.50. This is the first I've been advised about it and it was from 13 years ago. Is there any way I can request that Centrelink waive the amount payable due to the time taken to advise me of the debt? It's a little hard to dispute their claim after so much time.
