Good thinking. The relevance rule is currently up to my interpretation, which isn’t ideal.

Those are useful suggestions for ways to make it clearer what is relevant. I think relevance is too complex to put into any hard rules without there being exceptions (e.g. Australian outlets also report on global news such as SBS on Californian earthquakes at least three times[1][2][3], USA is one of our major trading partners, some people may believe the Pacific or all of Asia is our region) and so I suspect the best approach is to use those factors as soft guidelines (e.g. “If your article is not from an Australian or Oceanian news outlet, and the article doesn’t mention Australia in it, it’s probably not relevant to this community.”)
