Unlike other Commonwealth realms, the Governor-General of Papua New Guinea is nominated by the country's Parliament, rather than being proposed by its Prime Minister, as is the convention almost everywhere else.
The appointment is made by the head of state of Papua New Guinea, currently Queen Elizabeth II, following a simple majority vote of the National Parliament.
No person may serve for more than two terms as Governor General, a matter made formal relation in Papua New Guinea.
Thus far all retired Governor-Generals have been knighted.
The Speaker of the National Parliament has been acting as Governor-General until today when Dadae was sworn-in by Chief Justice Sir Salamo Injia in the Parliament chamber.
