Americans generally have a very good opinion of Aussies and see them as different from us and certainly not trying to be like us.
This is correct and pleasant and is as it ought to be in western Judeo/Christian culture with shared geo-political alliances.
Then there are times when us Aussies think that Americans are really on another planet and perhaps nobody can quite phrase the feeling as concisely as the Aussie actor Hugh Jackman did here.
