Gigi, if you go to "Women" in the business/govt section of the whitepages, there are a number of services that may be able to help you, either by providing you with additional information, or by actual service provision.

eg
Women's Information Service 8303 0590 or 1800 188 158
The Women's Housing Association 8349 4460
Women's Legal Service Phone Advice 8221 5553.

It is definitely worth ringing around as much as you can, before you make any decisions, and very worth seeking legal advice first. The Women's Info Service provides FREE legal advice over the phone & they would have some more info on services available to you so try ringing them first. And of course if there is any element of Domestic Violence/Safety issues, there is lots of help to get you out and into shelter accommodation, so don't be afraid to ask for assistance if that is the case .
