mosman is right.. mother, father, brother sister.. state or employer.. thats your lot. best option really is employer sponsored. state sponsorship, still runs on points system, so that may well not work.
no.. simply.. she needs lots of money.. the rules are mother father brother sister for sponsorship .. but i think there is a lot about having money for health care needs etc.. when we looked at it for our parents it was $250000 per person sponsored. So.. what visa did you apply for? sounds like you need to get a job first.. come on a 457.. ( employer sponsored) then look at getting employer sponsored PR 856 after 2 years. My dh would never had become a resident straight off as he didn't get the points. but now we have PR on employer sponsorship. quantity surveyor.. surely the mines need him? rio tinto or similar?
