Oh dear....if the financial affairs are already out of the family's hands I don't like your chances of getting any other workable arrangements in place.
Again, my knowledge is confined to NSW but my father gave POA to a family member many years before it was needed and when his mind was very good. By the time it was implemented years later his mental state was variable....sometimes good, sometimes away with the fairies. He kept asking various members of the family to do things that they did not have authority to do....it was a general mix up all round as he forgot to tell other members of the family who was doing things for him.
Eventually we got him on a good day so to speak and suggested a joint guardianship....the POA holder and another family member who he kept insisting he wanted to look after him.
The paperwork went through without a hitch as we were lucky that Dad was having a good week and was able to understand what he was signing.
But it was still virtually unworkable....while both guardians were able to give permission for medical treatment etc the whole arrangement could only work if the holder of the POA gave permission for the bills to be paid....if she said "no" then the other guardian would be responsible for the expenses of what they had authorised.
While your family may get a guardianship order they can still not authorise anything involving money without agreement from the Public Trustee.
All I can do is wish you the best of luck with it all....you will need it.
