Is this about multiculturalism?

In a way, yes: becoming a republic is about declaring our unity as one Australian people, and sharing our allegiance to our fully independent Australian nation, whatever our cultural and linguistic background.

An Australian republic will honour and respect our unique Aussie identity drawn from people from all around the world and ensure that Australia's head of state should not be chosen because of national background.

Our system should never favour one nationality over another.  Every Australian should be equal in our society and in our democracy.
