So, Australia. Following the end of World War III, the British Royal Family fled London. They originally intended to head to Ottawa, but Canada was already in the throws of multi-sided civil war (royalists, republicans, communists, fascists and Quebec separatists) so they fled to Australia, long a bastion of monarchists. Most of the Royal Navy (and whatever was left of the Royal Navy's Rocket Force) defected to Australia, as did many British colonies. Australia's population began to boom as refugees from around the Commonwealth began to flow in (and atomic energy had opened up vast swaths of the Outback, though settlement was slow at first). It also (controversially) inherited the United Kingdom's permanent seat on the UN Security Council.
The current Prime Minister is Kirsten Bryce, the leader of the Labour Party and the first openly gay Australian Prime Minister. She's the first Labour Prime Minister of Australia in over twenty years. The primary opposition party is the centre-right National Liberal Party, but the rise of the far-right (in the form of the New Country Party) has many concerned. Australia has one of the world's largest economies, though like many nations in the G8, its economic growth has slowed in recent years (though not to the degree that the American, Chinese and Soviet economics has).
The current monarch is Leopold V, of the House of Windsor. He succeeded his father, Edward VII, in 2079. He's the fourth Commonwealth monarch to reside in Australia (George V, Leopold IV, Edward VII, and himself). He's married to New Zealander journalist Anna Green-Boyle, and they have four children together. His heir is his daughter, Victoria, Princess of Wales (the Republic of Wales has politely asked if the Royal Family would kindly stop using that title, but to date, the Royal Family has declined). The Commonwealth realms adopted equal primogeniture in 2013. There has been talks of marrying Empress Victoria of the United States to Prince Albert Victor in order to cement the American-Australian alliance, though such a marriage is controversial in the United States (constitutionally, a member of the Imperial Family can't marry a member of foreign royalty with a special dispensation from Congress).
