A monarchy on the other side of the world is a complete joke to have as our head of state. A republic is 50 years overdue.
The whole concept of a born to rule hereditary monarchy somehow survived even though it has had a few use by dates: e.g. Magna Carta, Cromwell, 1776, the French Revolution, European revolutions in 1848 to name a few.
Also, the queen of Australia 100% supported the poms in sporting events vs Australia her while life. Aussies loved her but we were always second or third rate in her eyes. And in the eyes of all her ancestors.
It would not surprise me to see all the commonwealth countries leave, and even the UK further downgrade the monarchy in terms of its relevance to government, and stupid australia would still be bowing and scraping trying to get the King’s or Queen’s attention.
