have you considered finding some facebook groups to try and set up some sort of care.. i know there's a pretty active pay in forward group for people in Victoria that has helped out a number of people, i'm sure there's also local community centers that you can call.. i think some have outreach programs (or even checking out the local Victoria "cool aid society" and see if she qualifies-or can point you in the right direction ) i'm not sure the age of your sister but there are a few senior outreach programs out there that may offer help
