Monarchy of Australia
The Balfour Declaration of 1926, changed the situation in the British Empire, so that United Kingdom and the Dominions (like Australia, Canada and New Zealand) were to be seen as equal and independent, but "united by a common allegiance to the Crown". This situation of independent monarchies was confirmed by the Statute of Westminster. The Curtin Labor Government chose Prince Henry, Duke of Gloucester (the brother of  King George VI), as Governor-General during the Second World War.
