I think Australians would recognise slurbs - heaven knows most of the populated areas of the nation are such - but we don't have a word for them. Unrecognisable in their ubiquitousness. Can't see the wood for the trees. Too used to mediocrity in suburban design, given up pointing it out. Too depressingly familiar to contemplate. etc.
furthermore: both the projects and the slurbs could be described as ghetto (adj.); however, while projects are commonly considered to be part of "the ghetto," only a very sordid slurb would be so classed.
