A friend who came to Australia on a working visa and now has a son born here, split from her partner also on a visa(she is scared of him) & moved out a couple of months before the lease was up. He has since absconded leaving rent owing and damage that wont be covered by the bond. The owners want them blacklisted and she doesn't want that as she is applying for PR in Australia. She spent days with friends cleaning the property and tidying the yard. Is she solely responsible for the outstanding rent and possible insurance excess or can the real estate chase her ex as well. Does this all depend on the signed lease agreement ?
