The plan looks sound and I feel if these individuals are going to use the NDIS budget anyway, they may as well recieve a service that suits their needs.

I reckon they should buy or build small to medium size facilities around metro areas nationally, that provide accommodation for small groups of these individuals. It would act as a safe place for them to recieve services such as recovery, personal development and transtioning into independent living. Each centre could have a small number of rostered and rotating live-in caretakers and all other service providers can visit the facility as needed. Not only could it be more efficient on the NDIS budget, due to the reduced cost of servicing a group rather than dispersed individuals, it could also bring economic value to each area through jobs and investment.
