Something isn't right Jady with what centrelink have calculated.
I would be getting back there yesterday n seeing if someone didn't stuff up big time and then be asking for backpayment $$ which might add up to thousands of dollars from when ? you originally applied.
I have heard of a couple with two kids getting paid about $900 a week (minus about 65 percent of what your wife earns) then u shld be getting about $400 or $500 a week minimum. Which might pay the mortgage etc....it helps. Just check the centrelink site n they actually have a calculator which tells what you could be getting paid weekly.
The rules recently regarding the payout/retrenched monies also changed on 1st Feb as well. I think whilst you are doing these other positive things to get $$ coming in, get back some of the taxes you have paid n get back to centrelink n see what they can recalculate again.
I reckon you will score a job from the TV show. Hope it all works out n great karma goes to great people so I know it will not be long.
They shld have had u smiling in the photo.lol
Good luck Jady.
