michah - i'm down in nsw and know of two hospitals (one private, one public) that offer a similar service. it's called a "day program" or they admit you as a "day patient". ie, you are at the hospital for most of the day, but can go home at night. if you have work or are studying, they will let you go to that, also.

i'm not sure what services are available up in QLD but would be surprised if there wasn't something similar?
