I do think it makes sense that remote communities are closed, and those people are brought in so as to access the use of schools, clinics and more support. My reason being that I heard a report of caring individuals would go around the houses in the evenings, checking on teens who sniff petrol and also get on the drink.
They also spoke of the clinic doing welfare/ health checks on mums with infants and found some infants barely toddlers had been infected with STD's. It goes without saying this is disgusting for this to happen, but it does happen, and if it were in the remote communities the child may have died because the lack of health cover by the clinic. So, do you let them live in a remote area, or do the right thing and have them in a larger community.
I think TA knows all the facts through his volunteer work and would hear about these happenings, and I think his terminology is spot on.
