Mathias Cormann is a formidable opponent and a trusted counterpart: a parliamentarian of the old school.

There are few of his calibre left in Australian politics, and we are the poorer for it.

Our politics differ, but we share a love of country, a belief in our institutions and a respect for one another.

It says something about this country that two migrants hold the leadership positions we do.

And it says something about our democracy that they can be personal friends.

I express my best wishes to Mathias, and to Hayley, Isabelle and Charlotte.
