If we move to a new community and the intent is not to get spammed by non-Australians, then my advice would be to do something similar to the Rage community.

Keep the word ‘news’ out of the community name so it doesn’t turn up when someone searches for all the news communities to spam to.

I’m not much fussed either way, I’m happy to set up a new community and archive this one if that’s what everyone wants. I’m happy to leave it with the status quo.

Personally, I’d probably go with leaving it and urge everyone to be stricter and report stuff that doesn’t belong. I only check the site a couple of times a day, but I gets reports on my phone and usually respond quickly.
