Hello Betraid: I'm sorry you are facing this most distressing experience! Since I'm not in Australia I have no idea what, if any, options there may be for you. And, of course, I also don't know how much over-budget you are.

Here in the part of the U.S. where I live there's emphasis placed on keeping people (especially seniors & people with disabilities) in their homes. (That wouldn't necessarily be the case everywhere in the U.S. But it is where I live.) So I guess the only thing I could suggest would be to see if there are programs or services available that would make it possible for you to manage in your newly purchased home.

Another service that can be available here is help with budgeting. And there are programs & services that provide free or low cost food to people who are low income, elderly or who have disabilities. Help with paying utility bills is sometimes available. I don't have any way of knowing if any of these sorts of things are available where you live or if they could help. But it would certainly be worth delving into... especially if you find you cannot stay in your rent-controlled house.

If all of this is simply too overwhelming for you to undertake, then your first step might be to see if some organization offers assistance that can help you to figure all of it out. There again, where I live at least, these sorts of services are also sometimes available. Of course, many times, people here don't get all of the assistance they need either. But there is at least the possibility under some circumstances. Hopefully services such as these may be available where you live too.

I wish there were more I could offer with regard to your dilemma. If you were here where I live, I'd have at least a small idea of where to begin. However, Australia is completely unknown to me. Perhaps there are other Australian members, here on PC, who will yet see your post & reply with some useful suggestions. My best wishes to you...
