Oh dear, you're in a huff now because I don't value citizenship and
ceremonies and fancy certificates which change nothing.

They change a great deal. If, as you have stated, you are neither
Australian nor want to be, you shouldn't be there. You live in a country
which has educated you, provided you with a job, medical care, and so on
(yes, you pay taxes - the absolute minimum you can get away with,
apparently, since part of your citizenship objection is the cost of
obtaining it). You live in a country that values its people - your comment
above reflects the value you put on it.

I'm saddened you're in a wonderful country, but glad you're not in mine.
