How many kids you having at home living with you, boy/girl...and how old? Maybe someone can help you out with actual gifts?
A couple of Christmases ago I was on the verge of being evicted. I'd recently become a single parent to three kids and was left with half the ex's debt, so all my centrelink money was going to that, and I did not and still don't receive any child support. I had no assets to sell, I rented a house, I didn't even have a car or a bed to sleep in at the time. I was invited to someone's house on Christmas day and ate good food for the first time in a couple of months and my stomach couldn't handle it as I wasn't used to that much food, I got really sick lol.
I couldn't afford presents for my kids, the ex didnt' buy them anything...but one thing that did really help was going to centrelink and explaining I wasn't going to have a roof over my head for Christmas and what could I do? They gave me an advance in payment, which was a cash advance of $500 (on my parenting payment), and I payed it back slowly over the next 6 months. If I didn't get that we would have been stuffed...so maybe that's an option for you? If your wife/partner doesn't work and you have a child/ren, she should be getting full parenting payment now that you aren't working, as well as a generous family benefit, also you should be eligable for the dole immediately since you were let go. If you are getting held up with centrelink, just give them a call and go in there, it does work and they do hurry things along. And make sure you ask about the cash advance!
Good luck mate, I've been there and had nothing to start from again and three kids to support, but things pick up eventually, you just gotta believe that they do.
