Demographics would suggest that homelessness goes in to the cbd because the services are there (Bourke st drop in centre run by salvos), while homeless in suburbs either hidden (couch surfing) or in shelters and srs.Yes i get it. My homeless people dont count to making a place crap but yours do. Do you read what you write?
There is no good data on cities. But given most people in those states live in those two cities then the data aint going to be much different from the state data. You act like melbourne has multiple times higher. In the end its about the same. Might even be slightly lower then Brisbanes.
Change your opinion when the facts suggest you are wrong. Be mature.
