Unless you are already a Nilkawtian, you are unlikely to know much about Nilkawtians at all. If you are an ordinary Australian, on the other hand, you are very unlikely to know much about other Australians, including extraordinary ones, with or without the assistance of a national census.
All non-ethereal Nilkawtians are dual and jewel citizens of Australia. That means they are usually unwelcome to display their enlightened leadership in Canberra.
The Nilkawtian Head of State is a world expert on enlightened leadership. Very few other heads of state have similar expertise.
