AI overview
I don't have any context provided to work from. You've indicated this is about "Template:Country data Australasia" from Wikimedia, but no actual template content, documentation, or details were included in your message. Without seeing the template itself or its documentation, I cannot accurately write the overview you've requested. Could you please share the template content or documentation so I can provide an accurate 2-sentence overview?
