I think Melbourne are only down to one.
Also, while I agree that the authorities have a duty to follow correct procedures when assessing importation of "new" species, I believe that they need to give zoos more credence as to their security, as PAT said. I can't think of any introduced pest species in Australia today which wasn't a deliberate liberation, be they foxes, rabbits, deer, starlings or anything else. Can anyone think of a major pest which has resulted from zoo escapes?
not a major pest currently, but the palm squirrels living wild in Perth and formerly Sydney were from those cities' respective zoos
Just because it hasn't happened in the past doesn't mean it won't happen in the future.

The whole coati business makes me wonderif the zoos are rethinking their options re South American species.
