Prompt: When Australia was made a colony, it was also declared Terra Nullius - land belonging to no one. I want to see child!Australia (possibly all the way up to his teens) having mental issues due to the split between his original inhabitants (who also have their own individual personifications, as he represents the country as a whole), the new foreign people who became his while still partially belonging to someone else, and the Terra Nullius doctrine.
