I am a University Student who also work part-time.
As part of the student loan program i was entitled to a $1050 payment at the start of year and half way through the year to help with student costs etc. I pay this back through the student loan help program through the government when I am earning more money..
Because of personal reasons I had decided to take half a year of from studying to focus of my own mental health and life.
Centrlink tried to tell me because I am not currently studying that I owed them money. But its not true, I had to prove to them that I was studying full-time 2017-2018. The people on the phone said that they can see that somthing is wrong and that I should not have this debt. They said it would go under review and that it could take 2weeks or it could take several months. The worst bit is, if I did not prove to them that I didnt owe them money then I would have had to pay it back. Its never easy dealing with centrlink and I honestly beleive they make it hard for people to know whats going on just so they can make our life harder.
