"The term 'nation' is used in its original sense to mean a people who share a common identity and culture and are identified with a traditional territory."
It's Administration has certain powers but they fall well short of the law-making powers enjoyed by the states. From Wikipedia: "Under the Australian Constitution, the Commonwealth has full legislative power, if it chooses to exercise it, over the Northern Territory, and has devolved self-government to the Territory. The Northern Territory legislature does not have the legislative independence of the Australian states but has power in all matters not in conflict with the Constitution and applicable Commonwealth laws, but subject to a Commonwealth veto."
I checked it with Wikipedia. Luxembourg = 166km2, Malta=316km2.
You should replace that!
