Look a website to show where city people are surprised to see foxes, it must be that, or Australia only has a few thousand foxes, with most of them in the city.

There's also a footer bar with different pests on it, the data sucks but it might show where there's something you want to hunt. Although I suspect camel sightings in Victoria may have been bottle shops.
