I hate the phrase 'centrelink cheat' why because when Hank ( you know the head dude) goes on TV he calls anyone who has been overpaid a cheat. Heck Im a cheat as i wrote on the form I was earning $8k PP ( 10 years ago) they processed but apparently entered $800..I ended up with a debt and it wasn't till a year later someone checked on my behave and said 'you didn't lie the staff member entered numbers wrong your form were correct"...woohoo..still had to pay debt.
My point is 'cheat' it to far ranging. Im with you I have a couple in housing comission in our street who's hubby does loads of cash in hand work from his home business ( probably alot more than we get from hubby's wage) yep it annoys me but at the end of the day..karma..I can sleep at night knowing Im doing nothing wrong..them well.
And yes also know a few single mum's who aren't and claim..annoying yes...but it comes around
