They don't go. Even if they do manage to scrape through and go out of desperation, they don't stay. If they try to stay, they're very often kicked out, which brings us to the other issue. There is no protection for indigenous people in non-indigenous housing such as transition housing.
There are huge numbers of dollars invested into housing, but they can literally eject tenants with no governance and no protection for those tenants. It's really different from private market housing.
