anyway...the Adelaide one is the fake.
The easiest way to determine one or the other as a fake is simply by the template. It's extremely unlikely that both South Australia, Australia and Coastal Province, Kenya, used the same template, including the same coat of arms (or logo) at the top of the page. Of course, it's possible that both the Kenyan and Australian are ultimately fakes for different reasons.
BTW, has anyone noticed that the folds in the Australian and Kenyan documents are in different locations on the template? Just wondering what the significance of that would be.
