I would believe that Italy, France and Australia or Scandanavia would have a 'covert' or destroyed sleeper ship, since they are Democracies and most likely allied to the Alliance.
If I remember the start of Starlancer right, the Italian and French fleets were annihilated by a Coalition surprise attack.:(
If Australia had one, it more than likely had settlers from all the 'Kiwi Islands', a mixed and vibrant culture.
I wouldn't shun the Canadians from having one, since in itself is a very large and resourceful country.
