@LoveLivesHere great advice!
having been in this situation myself I can fully appreciate the frustration. Unfortunately, with me, centrelink took the view that I was not at risk of major violence and I was able to stay with family even if the situation was not desirable. They did not care if myself and child(long story but dp and I were yet to become a serious couple even though we had a child together) were only able to stay with someone who refused to smoke outside, swore and screamed, was often irrational and did not keep the tidiest or cleanest of houses and had a violent and aggressive relative in their care. All centrelink cared about was that we had a roof over our heads. That's it. I did the couch surfing thing with a baby/toddler for about 2 years before dp and I got our act together.
People, this is a new member. Please don't scare her off. She has come here, like many of us, to vent.
As for practical advice, there are jobs out there. Maybe not highly desirable, or even slightly desirable. They may not be in the graduated field. But there are jobs. If things are really bad, there are also caravan parks you can often find accommodation at. Government housing is a good start. Put your name on the list. It can be a few years waiting list though. Salvos and other charities can often help out as well.
They have given you a roof over your head and you should be greatful but it doesn't necessarily mean it's the best solution for you.
