Queenslanders have been urged to carefully check unexpected debt letters from Centrelink and other government agencies.
A 9NEWS investigation has uncovered a string of alarming errors as frustrated families are accused of owing thousands of dollars.
“When people are receiving these letters they're automatically assuming that they owe a debt, that's not actually the case,” James Farrell, from Community Legal Centres Queensland, said.
Thousands of automated debt letters are being generated by a new Federal Government computer system that cross-checks all payments with tax office records.
Federal member for Lilley Wayne Swan said errors in some documents were a result of the Federal Government using a “quick calculation of debt”.
“In many cases, it’s inaccurate,” Mr Swan said.
University tutor Andjre Panjkov successfully challenged his $3000 debt.
“It was a total fiction they were saying this invented average fortnightly income was my actual income and my actual income at that time was zero,” Mr Panjkov told 9NEWS.
“I think the way the system is set up is they're hoping that people will give up.”
